Hi all, hope you enjoyed our latest video. If you want to get your hands on some of the equipment we used during the video, then there is a few links in the description for you to go look at. 😎
@artisanelectrics I like your content. Just have a question on this video and some feedback. With how you have finished your safe isolation. Suggesting that you turn that circuit back on to prove your test equipment just after you have test for dead defeats the objective of proving dead. If using a know source to prove your test equipment you should be using a different source/ circuit. Hope that makes sense.
Here in the United States all metal boxes need to be grounded you would say earthed and all ground leads need to be twisted together and crimped so they do not come apart.
You may want to edit your video, to mention, that not earthing the metal type backing boxes can result in the fixing screws for the front plate becoming live, this is even more dangerous, if the front plate used is of the metal type, as the whole plate becomes live, and mere contact will result in potentially a lethal shock even with the protective RCB in circuit.!!!’ Stay safe out there, from a old long retired sparks, thanks for the video, people do stupid things and learn unfortunately their last lesson!!!’ It’s what the Darwin Award was created for!!’ ຈل͜ຈ .
This is one of those rare videos that properly explains why, not just "because regs" or "that's how I was taught". Much more convincing imo to the casual DIYer who might otherwise be tempted to bodge it. Well done!
I already like this video even only 10 seconds in! The attitude of "I know you'll do it anyway so here's the RIGHT way to do it." This is perfect! You'll never stop the DIYer from doing simple things like sockets so at least having good educational sources out there to try and keep them safe is a life saving thing!
I really agree with that. At least where I live (in Sweden) way too many electricians have the attitude of "don't mess with your electrical installation your self or you will die or burn your house down" - and even some sellers in hardware stores refuse to answare questions about electrical work (even though you can buy all the stuff you need). That's because of our stupid laws. But many of us don't give shit about those and I also read that like 50% of house owners have in fact done electrical work that's not allowed anyway (because even simple things like connect a washing machine to screw terminals on the wall, requires an electrician to do legally here) and very few people get caught (and most of the cases where someone have been, it's almost always illegal paid work or if they have done a bad installation on someone elses property, that have caused a fire or a similar thing - which is a whole other thing). The other 50% is probably mostly people who really know nothing about electricity and would have an electrician do any work anyway. So this shows how dumb that attitude (and laws) is, as they will just contribute to making installations less safe than if information is spread how to do the work correctly.
@@Speeder84XLHaving written negatively about most electricians I've used and positively about diligent by the book DiYers, I have to support the shop that won't give advice. There are books, regulations that can be downloaded, and good UA-cam channels like this and effix. Shop is right to protect themselves from accusations of saying the wrong thing or someone doing wrong despite the correct thing they heard
@@cuebj That's true. I was refering to what I have seen in for example some chats and forums - things like "when I worked at a hardware store, I refused to answere any questions about electrical work as people shouldn't do that them self". Which sounds to me like those electricians. But, now when you say it - it's pretty obvious that the stores (and the companies running them) don't want to deal with someone doing bad work and blame it on them. Especially since out "electrical safety authority" (which is most likely heavily influenced by lobbyists from electric installation companies) have been on everyone selling electrical equipment already and forcing them to for example put up signs, "all electrical installations have to be done by an authorized electrician". So, if there is for example a fire and someone blames it on the advice they got in the store, they would in fact likely get sued for causing it, by helping unauthorized people do electrical installations.
@@artisanelectrics I've been doing most of my own electrics since I was about 10. I'm now 68 and still alive with no more than a handful of belts to my name, so I must be doing something right. My father was an engineer and my next door neighbour when I was growing up was a sparky, so I picked up a lot. As my username suggests, I've always been fascinated by test equipment, and have amassed a fair bit over the years, including no less than three MFTs (Fluke 1664FC, Megger 1552 and 1741..!) I've also taught myself how to use them, so although I'm not qualified, I do feel I have some idea what I'm doing.
Thank you. That was a lot less harsh and a lot more informative that I expected. I've replaced many sockets, switches and light fittings in my house, and put in additional sockets as required (who thought that one single socket per room was enough in the 1980s?). I always try to keep up to date with proper practices and safety and will call in an electrician for anything that I feel unsure about. I agree about making sure the wires on the sockets are long enough. Unfortunately with my house cost came first and all wires had been installed as short as possible! I also like deep back boxes to give plenty of wiggle room for the wiring.
Some nice tips. Interestingly as an industrial spark, I’ve often shuddered at the work of domestic sparks. I’ve lost count of how many socket faceplates I’ve removed to find either excessively short cables, loose terminals or both. The worst case I’ve come across was my parents shower installation. The shower had stopped working, when I investigated it for them the shower isolator was burnt out from a slack termination. It required a new switch and luckily in this case there was enough length to re strip some fresh copper. It’s a pity not all electricians are of the same good calibre.
shower pullcords etc are a nightmare, as is 10mm T&E. Never enough room in a single backbox really. Although T&E is a terrible cable choice too. SY cable far more suitable.
I’m an electrical engineer. I have degrees and everything, I then followed on to do an apprenticeship in an electricity company. I would love to say all electricians are good, but in the three houses I have owned, I’ve found over 30 issues with the work “professional electricians” have done. From wiring extra sockets off a lighting circuit, to not bothering with earth connections onto metal light switches. It’s a shame no one can be trusted to do a safe job.
One thing I found in mine not really anything wrong I'm guess it's fine to bring wires through a joist but some of my light circuits come through the joist so if you want to fit a low profile light and need to pop a junction box up into the ceiling you can't. Pain in the arse as the one I was doing is right under the board for the old water tank somcant pull it up to then drop newmfeed down and can't really cut the ceiling as has asbestos artex.
Such a stupid thing to say from an apprentice 'its a shame no one can be trusted to do a proper job'. Despite clearly having watched this video where t job is done properly u claim this - most bizarre. 🤦
@david-iandawson Well what do you expect when someone begins with "I'm an electrical engineer."? It doesn't matter which side of the Atlantic you're on, those idiots seem to think that carries weight to electricians in the field.
@@danieljadorie829 I totally agree. It's the arrogance that baffles me. To claim they know what they're 'talking about' shouts out to me their crappy character. Whilst moronic folk like this claim to be competent, u just know they'de sink at t first hurdle attempting to claim they can do t job of a qualified sparky who has experience. We must be on t same frequency - no pun intended 😁😂😂😂😂
Some good points there, in regards to depth of the back box, as an alternative you can get spacers to go around the socket, effectively making them sit proud, some might not be happy with the look but it's a definitive alternative to having to excavate another 10mm of depth into your brickwork.
Yes Dave I am glad you mentioned the double socket spacer ,easily bought on Amzn. I am a retired electrician and I have some serious reservations about home owners working on wiring. I am sure a thousand sparks would agree that like me on removing sockets they have found often an amateur dangerous bodge-up mess. From incorrect under size cables and no grommets to multiple spurs taken off , broken ring circuits ( which an amateur would not look for) although Jordan has presented a clear informative vid the though of homeowners changing sockets makes my blood run cold.
@@garypautard1069 I couldn't agree more and it's not just the DIYers unfortunately. In a previous property that i lived in (for about 12 years), I was surprised at the number of junction boxes and also choc-block connection block "spurs" and joints. As it was a council house, i was fairly limited, but whenever contractors came in to do other work (such as adding central heating, new smoke/fire alarms, electric shower etc) I always managed to find and fix previous "bad practice" situations overnight while boards were raised and cables exposed. If/when contractors had boards up for access that exposed existing wiring, I'd ask them to just leave them up overnight seeing as they'd just need to lift them again the following day. Then I'd identify whole masses of spaghetti and various types of junction (often with no earth sleeving), as well as multiple spurs from a single box. Then I'd either reroute cables or replace whole sections to recreate a single ring without any junction boxes. Securing cables, adding sleeving and removing as much of the tangled spaghetti situation as possible. When the contractors completed their work, the test results were always better than the readings from before they started. There was only one thing that i missed, which was the pull switch for the shower. When they installed it, they siliconed the switch and i didn't want to break the seal. 18 months later, the shower stopped turning on, so i opened the switch and discovered badly charred wires, the live just slid straight out - obvious that the terminal hadn't been tightened, causing sparking every time the switch was used. There was so much damage inside the switch, molten plastic, black charred wires and contacts, it's a wonder that it hadn't caught fire. Even though there was plenty of space available in the attic directly over the switch, whichever electrician did the install, cut the wires extremely short. When i replaced the switch, i ended up moving it 6" closer to the bathroom door so that i could trim the burnt cable and have enough good/virgin wire to make good connections. (6 years later, when i moved out it was still in perfect condition).
@@garypautard1069 Just been working on the electrics of my present house which dates back to the mid 80's and some of the original work done by so called professional electricians is shocking, excuse the pun. It's been the same in two other houses I have owned. Hopefully, standards are higher today, but sadley there are cowboys in all trades...There some jobs I am happy to do on electrics around the house, while there are others I prefer to call in a qualified spark...I have had quotes from one of two over the years that I have rejected because of the way they intended to do the job. I remember one who wanted to spur an outside light and an outside socket direct off the house lighting cct rather than put a separate cable back to the consumer unit which is what I actually wanted. The consumer unit had space in it and was located in a convenient place meaning there would have been little difference in the cable runs. The only added difficulty was that the guy would have had to work in the consumer unit which he seemed reluctant to do.
@@garypautard1069 Don't paint us all with the same brush though please. Those of us who watch videos like this are educated, all for the better. I have had all of the work I've done in my home over a period of 40 years checked and certified by a qualified and reputable sparkie who was very complimentary. His only negative criticisms were of some of the original builders' work which I had not touched.
Great video. Another tip would be to check if there are rubber grommets installed in the back box. I have seen so many without them. Worth adding if they are missing.
I actually use a sharp needle on the end of one test lead to check continuity between the terminal screw and the wires by pushing the needle through the wire insulation as close to the terminal as possible. And yes it will leave a tiny hole in the insulation but so small as to be irrelevant. It absolutely confirms the wire is connected to the terminal correctly, very important for a ring circuit which might otherwise be broken if one wire isn't actually connected properly.
A very clear and concise article apart from one thing. Trying to get a sparkie who is willing to do a home visit just to fit or test a single socket. It aint going to happen. If you can get one they will charge a fortune. I'm lucky I have a working knowledge of this sort of thing and the appropriate tools but luckily my neighbour and friend is a tutor at an electrical college and so he's fully up with the regs and gives me good advice in advance of any projects I have and has got me out of shtuck more than once. My mate needed a 30 year old bathroom light replaced after it stopped working due to the bulb contact points breaking down. His local spark wanted £200 for what was to him 10 minutes and he lives in the same street! He didn't even need his van! I did it for the cost of a box of wago connectors. A lot of these vids all state that if you can't do the job or don't feel confident about it call a professional. Sound advice but getting one? Good luck. 👍
When I moved in to my last house, the garage was powered by a bit of trailing 4mm that the previous owner had installed. I'm very comfortable around electrical systems - I'm an electronics repair specialist - so I rewired the entire garage, including fitting a small consumer unit to separate out the boiler, lights and sockets. Getting an electrician in to check the work was an absolute nightmare; I wasn't comfortable using the new accessories until they had been checked by a professional, and in the end (after over a year) I managed to swap 'work for work' and fixed an 1662 (electrical testing unit) in exchange for the work. I'd have had no issue paying for the work to be checked - even above what would be a fair amount of money for the work - but unless you're offering them a job where they can charge ridiculous amounts of money, my local electricians just don't give a damn. I can't imagine how frustrating being in a similar situation would be for someone who's taken the time to learn how to, and then carried out their own work, only to hit a roadblock because of lazy/avaricious sparkies.
You are both absolutely right. I can do simple stuff but cannot do PAT testing or EICR reports obviously but getting anyone to even ring back is a nightmare. They all complain on these U tbe vids about "amateurs" but not returning calls because they cannot be bothered is just rude and pathetic.
@Do you find so called mates or neighbours, then say 'oh that didn't take long' and hand a token fiver or nothing at all, yet often they're willing to pay a professional a couple of hundred for same job. I gave up being kind but rather late in life. I find it hard to say no to help others.
@@DavidMartin-ym2te I got myself qualified to do PAT (not PAT Testing please, that says Portable Appliance Testing Testing, which is silly..!) and have done all the equipment in the house. It's amazing how many things there are, you don't realise until you go through them..!
This is one of those rare videos that really explains _why_ to do this or that, not just "because regs". Regulations are important, but they themselves exist for a reason, and these reasons are imo more convincing to a DIYer who might otherwise be tempted to bodge it. Well done!
Before taking sockets or light switches off, loosen the screws 1 turn and tap the socket with your screwdriver handle. It will crack the paint seal, preventing chunks of paint breaking off.
When fitting the socket back into the box, it's important to check that as you bend the wires, none of them are directly behind the face plate screws. It is possible to tighten a face plate screw through a conductor that is immediately behind it, thus creating a short. Thx for the detailed video. Most helpful
I have done many of these in my house just using Google search to remind on colours and common sense - and did everything on your list (except earthing the backbox - I was happy with the risks relying on the screws to cover that)! So yay for I guess my Dad who must have taught me this stuff when I was growing up - I think he must have instilled the right principles/practices when messing around with electrics. Cheers anyway for the video! Another simple way to test for live is to grab a phone charger: have it charge your phone before turning off the socket ring main, then turn it off. If it stops charging - it's probably the right ring main/circuit. Do this process twice and it's almost certainly the right ring main. I recently bought a Klein tester to triple check the cables too, so slightly disappointed to hear they're not always accurate. But I figure it's better than not doing a wire test as a triple check. A DIYer isnt going to spend the presumably £800 or so for those posher testers....
Are you having a laugh? If you're being serious, let me give you some advice....don't go near electrics. And if you persist, invest in an audible socket tester.....forget all that phone charger stuff.
A screwdriver with a light is more than enough. 🙂 First, check that the light is on, then turn off the main or line fuse and check again. It's not rocket science. 🙂
I was a bit surprised at the back box not being earthed. I was told by a electrician the it was a requirement. I went around the house each time that i decorated a room and added an earth to the back box. Then I am confused why plastic dry lining boxes have an earth terminal.
Over the years I’ve had tons or cross threaded back boxes. I got a rethreading tool (taper tap) and never had to use it since…… bugger 😂. Nice video Jordan.
Great video, I think its worth mentioning that when isolating at the fuse box, not all isolation points are double pole, so you still have a potentially live cable, the neutral. And as you know because its potentially live, current will flow between the neutral and earth, if there is an rcd this will trip if not, you get a tingle! I would always recommend a DIY'er to switch the main switch, or call an electrician. Its nice to see that in some installations now in the UK people are using double pole isolation (rcbo).
An RCBO is a device that combines MCB and RCD functionality. It has nothing to do with whether it is dual pole or not. Both are available, but not from all manufacturers. Dual pole breakers are convenient for some type of testing, but they do not add much to safety in countries where circuits are routinely polarised. If there is a requirement to isolate both line an neutral, then there is always the main switch. That cuts off all the power, but as I mentioned, it is primarily convenience, not a safety issue.
@@zaxmaxlax Whilst it is true that RCDs (and therefore RCBOs) have to have both line and neutral feeds, poles refer to the breaker part, not the detector (and switches in general). In my case, the RCBOs in my CU only break the phase line, not the neutral line (which is what the overload function does too). There are diagrams on every RCBO showing whether it breaks both lines or not. Mine most definitely only breaks the phase line. So, no. You have misunderstood the terminology. Poles refer to anything that breaks or switches circuits, not to detection devices. Stand-alone RCBOs are most often single pole, as are most MCBs, at least in the UK. RCDs will almost invariable switch both poles.
I can add a tip I learned the hard way. Make sure you don't trap any of the wires when putting the face plate back. I accidentally pinched a neutral wire between the end of the face plate screw and the back box. The insulation wasn't split so there was no direct metal to metal contact, but it was enough that every time a load was switched on, on the same circuit, the trip would shut it down.
The more important reason not to twist the cpc's is that they will still show when testing that they are connected even though they may have fallen out of the socket itself. The earthing of the back box can be essential if you do not have a fixed lug that the screw goes into.
Ive yet to find a socket screw connection block that will safely hold three conductors without tightning to the point of crushing the conductor (the screw usually only impacts and holds 2 of the 3 securely) so in the case of a ring socket which is feeding a spur I twist the last 15 mm of so of the earths.
Surely testing the earth through the socket is a required test after changing one in the UK. Even a basic plug in tester will pick up that there’s no power across the phase earth if the conductor have come out the back of the socket.
I'm confident to undertake tasks like this and my working practice is that I have passed all your advice 100%, I'm super cautious with electricity. As an very experienced senior Architectural Technician, the one bug bear I have is front plates not being level. I happens far too often, mainly by apprentices, their gaffer should take much better care in teaching the apprentice the correct working practice. I saw a front plate and back box 15mm out of level 4 months ago. The guy who owned the company was on site, I pulled him about it and he thought is was funny!!
15mm!! That has to be a record over such a small distance!! And there's me making sure the spirit level bubble is in the middle of the black lines as there is always space each side.
The consumer unit in the video would benefit from being out of level by a few mil, for when that washer drain pees water all over it! At least some of it would drain away...
When I checked replaced some sockets recently in my '2004 new build' home, with the entire house wired by the George Wimpey spark, I found every socket had the CPC's twisted and sleeved by the professional!
before the current fashion for EICR's, many installations in the 60s and 70's had twisted earth wires on the rings. And digitial testers were yet to be invented. Our family's electrician had an AVO 7 and a neon screwdriver, a wind-up megger for tricky tests and a Vauxhall Viva with a ladder on top.
Worst thing I ever found? A domestic socket in an extension, on a ring, each end of the ring fed from a different circuit breaker. The householder was pretty proud of his wiring 'skills' too! I very nearly walked away from that job but I persevered and persuaded the guy to pay me to do a full installation check. That the threw a few more faults like poorly connected equipotential bonds to the service pipes but nothing too major. I put another half turn on pretty much every screw terminal though (with my calibrated torque screw driver)
Love watching those videos. As I watch videos from people around the world about electrical stuff, it's funny to see the differences. I'm from Germany. You wouldn's see something to screw in a socket over here. So nothing to get loose over time and cause sparks. But I do like the buttons you have on each socket. Also a main switch is not mandatory over here in the distribution boxes. It is mandatory in the main distribution though nowadays. But don't expect that in older installations. Usually an RCD will do that job if present (again, depends on how old that stuff is). When we took over our house, they only way to power down the complete installation was to pull the NH fuses. Worst videos about electrical installation usually are videos from the US. Their stuff looks dangerous compared to European standards. In regards to cable colors. We use the same as you do. If you find something old from the 60s, red might be earth, neutral gray and black and blue would be live. So if you see red cables over here, be vary careful what you conned to what.
What about Italy? Twisted conductors under a thimble connector, no form of EICR so the installation is never tested and relies on faultless original execution. Live is grey, black, brown, or red even in a single-phase domestic installation and there seems to be no consistency as to which colour live is used for what.
Very interesting. I know how to wire north american outlets and so many differences. One old tip that still works well, plug a radio in the outlet when you are at the breaker panel. You know you've got the correct breaker when the radio goes silent. When you are dealing with old houses with poor labeling of circuits it can be a lifesaver to not have to run back and forth to the breaker panel. Test properly after but it's a good first step.
Got some (decent brand) faceplates from an ebay seller and delighted to find they threw in 2ft of earth sleeving. made me think that for DIYers this should be normal rather than an exception.
After isolating, the first thing to do is carefully run a sharp blade around the circumference of the socket. Saves it sticking and pulling paint etc. with it. Hopefully stops the other half recommending redecorating!
Worth it if you weren't the last one to decorate, but I'd go further saying first step is to make sure the sockets etc are loose from the wall and paint allowed to dry properly in the first instance. I do hate it when lazy decorators paint or paper up to sockets and switches instead of doing the job right first time.
Im am 53 years old. i qualified at 23. I have not done much domestic work for years (tended to spend more time moving furniture than working, and then theres the customers🙄) but i can honestly say i have never, ever used a spirit level when changing a socket, thats a level of dedication i never managed to reach!
@@artisanelectrics In fact, if the socket is close to a ' not quite horizontal' skirting board, it should be installed parallel - otherwise it will look very odd!
Wow what a video you shared there. It was really eye opening to see how many little mistakes can happen when you're swapping out sockets at home!. Your pointers are super useful and will definitely come in for preventing any mishaps, down the line while dealing with electricity work in the future so thank you for sharing such valuable advice with us all!
If you're wiring up an all metal light fixture on the ceiling, make sure that the switched live doesn't get smushed between both halves of the fixture. I've done that in the past and I was glad I had grounded the light fixture, as the result was blindingly spectacular. And loud.
Many years ago a neighbour asked me for help fitting a metal ceiling light fitting. He knew it should be earthed but there was no earth cable. I assume for some reason who ever re-wired the 1930s house just cut the earth wire off. There was no slack to pull any cable through.
I watched this again before replacing a double socket with built in usb in fhe FiL's flat. The wiring is from the early nineties. The wire tails are imo way too short. It made securing a bit awkward. The earths were twisted together so I separated them and used some extra sleeving. Thankfully all went back and tested well. The dodgy socket was a gb fitted by a local oddjobber during covid. I replaced it with an MK one. Thanks for the tutorial.
I am so pleased to hear you stress about proving the circuit you are about to work on is beyond doubt … dead, verifying you see it switch off as you knock the breaker off - remembering someone could have reversed the L and N connections too! Breakers can and do fail (older mcb and mccbs may not be positive indicating) and sometimes circuits aren’t wired as you might expect or the Reg’s dictate. You missed stating ensuring that everyone who may be in the vicinity knows the circuit must remain dead and must not interfere with anything until you give the all clear (lock off and tag - would be the ideal), verbal, visual/ signage. Use the right tools too - cutters for cutting only, wire strippers for stripping insulation. Check copper not kicked at the strip point when removing insulation. Not a fan of looping the end of the stripped wire as you stress the copper on such tight 180 degree bends, if it’s clamped on the return bent end and not the straight copper then you are passing current through a reduced cross section and thus derated cable on the bend! In my opinion always better to keep straight and ensure conductors are seated correctly in the clamp. I always have a separate earth back box to the socket (ring earth paired on the other earth connection - standardised on double sockets so can do) that covers you where the box screw threads strip or are loose and could become live. In machinery and associated cubicle/ panel building wiring (to EN 60294-1) you are not allowed to use any securing/ mounting/ fixing screws to be used as an earth - the earth has to be a separate stress free connection. So still surprised wiring Reg’s have not caught up and don’t dictate domestic sockets are structured to ensure this best practise. Above all do not rush, check what you are doing - professionals make mistakes when they rush or get distracted too! Good to see your wire pull tests on individual connections. The devil is in the detail, well done.
But he said doubling it over not to have double thickness, but to take into account that only a single wire is being put into the terminal, So either you have a single CPC going into the terminal, or you have a single and another wire (doubled over), which basically means two wires and I presume most likely better grip, and even if the bend breaks, it's still one/two wires which was the intended purpose.
Watching this as I have 2 switches that wont push in anymore rendering the sockets useless. You've scared me into getting an electrician now and ill be watching their methods. nice video, thank you.
May I humbly suggest that as an electrician, you may not want to be wearing your wedding ring while working. There are too many places/times to have that metal interfere with your work protocols : Bumping into something live, getting caught on any kind of protruding wires/metal/construction etc. Any kind of jewelry was banned from anyone working construction of any kind in my company. Rings, necklaces, earrings, etc. were all required to be left at hime.
There is indeed a very serious risk resulting from wedding rings, metal bracelets, metal watch wristbands and similar when working around circuits with large batteries: if a short circuit is created by the ring/bracelet, the ring/bracelet may get welded and become incandescent, cutting your finger/wrist or at least causing very serious injuries. This is the reason why I never wear my wedding ring or watches with non-plastic wristbands.
It is a very good point, I remember years ago my grandfather got his wrist watch across the positive of a car battery and the clamp holding it down. Obviously there was no risk of electrocution but a very large current quickly heated up the wrist strap causing a bad burn. Even extra low voltage systems capable of delivering high currents can be dangerous
I agree, I'm not married but my boss (who was) always left his wedding ring at home. A band of gold, one of the best conductors, will make much better contact with the skin than just brushing past a live wire with the back of a knuckle. You tend to sweat under a ring as well, just to make the contact better.
Great video - well explained thankyou. I'm a keen DIY-er and have changed many socket fronts. I recently added a double socket spur of an existing double on the downstairs ring. I found the existing socket didn't have a cpc to the back box - so added it in and did the same to the new socket. So to my mind I've made a better job and improved the installation as a DIY guy - who's not under time pressure, than the professional who might (and did) cut corners to save time. Btw - I would only ever mod existing circuits and never run new before someone reaches for the wooden spoon ;).
Excellent point about DIY not under time pressure, except from spouse! Trouble is, you can offer a professional a bit extra to take a bit longer but their instincts, honed by quoting low to match low expectations of most domestic customers, override your offer so they still do quick sloppy work!
Make sure there are grommets in the cable entry holes in metal backboxes. If you start a job like this and realise you don't have any grommets you're definitely going to 'conveniently forget' about them.
It's easy to fit a grommet after the event, and that's just to run a sharp knife through it and the you can fit it over the cable and put it home. There's not danger of touching the cable touching the metal back box as the ends will be pushed together. It's also a useful retro-fit as many back boxes did not have grommets installed in past years. Saves having to disturb the connections.
Its also worth having a 'Socket Outlet Tester Receptacle Tester with Voltage Display Automatic Electric Circuit Polarity Voltage Detector' to double check the wiring is connected correctly in the socket.
Great idea having that "'Consumer Unit"', as you call them over there in the UK, next to a washing machine drain. Asd a Sparkie, that would have sparked my interest straight away. I personally would make them move it or I'd put in defect notice on the property.
Rubber grommets around the wires where they come through the metal back box. I'd have put that on the list. Tight wires against sharp metal might cause the wires to wear through if stretched. Also, you might need to buy longer screws if replacing the back box. And, very importantly, make sure nobody in the house could accidentally turn theConsumer Unit back on. And tell people what you're doing so they know why the power has been cut. In a family house where you're the only adult going near that's ok, but on a job with other people working there it's an obvious issue and it might need locking closed.
Grommets are nice to see & good working practice but not a requirement. So you cant really put it down as a customer mistake. & no doubt same as myself you've seen plenty of so called proffesionals that can't be arsed to use them.
I used to suggest to sparkies I worked with to take the fuses from industrial switchboards with them whilst working on jobs. I know of two occasions where people have seen fuses left on the top of a board and “helpfully” put them back in. It’s the most silly mistakes that can kill the sparkie, always protect yourself first. Times have changed re safety over the last forty years for the better, but an idiot today can still kill you just as effectively as they did years ago.
Shows I am getting old. I was doing job or other and had the consumer unit switched off. Finished the job but for some reason didn't switch it back on. Probably got interrupted. Later on for the life of me I couldn't work out why the kettle was taking so long to boil. It did eventually sink in.
Not a good idea. The pipe can build up silt over time and back up during a drain cycle. Been there, done that, but not a couple of inches from the mains!
I had an electrician come round to change sockets, and he did it with it still live. I told him to switch off the power but he seemed confident. I don't know if he was wearing some special clothing like they wear when working on pylons, but as far as I know, he's still alive.
One important thing missed. After proving dead ensure the cb is prevented from being re-closed so someone doesn’t come and switch back on while you’re working on it. Or at the very minimum tell everyone what your doing and not to switch it on
Just modernised and added some new sockets on our home- an ex council house from 60s. Our main issues: -Shallow 16mm back boxes needed to be replaced by 25mm -Earth connector in 1gang metal back box was directly behind the screw lug -No grommets on back box meant the mains wires had been worn to bare copper -some VERY tough bricks to chisel into to allow for deeper boxes I also once repaired a faulty light pendant- I turned the lights breaker off but the other lights stayed on, they had been wired into the fire alarm breaker!
Also if you reverse the live and neutral the fuse will be on the neutral. It can cause various risks like it can blow and leave voltage on the device or in case of ground fault it will be bypassed.
Tips for gettting the machine screws back in would be good. Some faceplates come with really short screws, so if the lugs are deep and you don't have spare longer screws, getting them in the holes can be tricky. I've been known to use cocktail sticks to get them aligned!
I worked at an Electric blanket factory many years ago; one colleague suggested we all go to his gran's house for lunch. On entering the living room, we found his gran lying asleep on the sofa wrapped in an electric blanket; I stepped on the carpet, and there was a huge bang followed by a large hole in the carpet. His gran awoke as the blanket smouldered; she was okay. I checked the power had gone off and lifted the carpet. To my shock, she had extended two different gauged wires with sellotape. She did not have a plug, so she used the classic match sticks to hold the wires in the holes. It's not a good advert for the Electric blanket.
My tip would be don't assume the wiring is as you imagine and test frequently for isolation. I gutted our house before a rewire but had the juice on for lighting etc. Entire house was on 3 old wire fuses (no MCB,RCD etc). Heating was via economy 7 night storage heaters isolated via a crusty old switch. Flipped the switch, did a DVM check to ensure no juice, removed the first storage heater and isolated the ends. Removed the second one, isolated the ends- on a roll! Unscrewed the power from the third, for some reason the dangling wires sparked my spidey senses- stuck a nice long metal screwdriver across the L+N- massive bang (though even that didn't trip the fuse). Turns out some genius had wired the last storage heater as an unfused spur off the ring circuit for the sockets. To this day not sure why I thought of "testing" it. Scary buisness. In my mind, an isolation switch labelled "night storage heaters" should isolate anything in the house purporting to be a night storage heater. Lesson learned. Other than the 3 wire fuses there would have been nothing other than the DNO 100A between me and the national grid.
When my sister-in-law rewired her parents' old house, the electrician found lead pipes with squashed ends of just poking out of the walls where the gas sconces had been; they were still attached to the gas main! I guess they had become redundant in the 1930s. It had been a council house until the 1980s.
Good informative video , a tip is to make sure the the wire in the socket are not behind the face plate screws as sometimes there can be upto 6-8 wires in the back box if it's a ring main with a spur coming off it.
Reversed polarity isn't "just" for the isolator ( switch). The fuse is always in the Live so the plug top properly wired will only "blow" the fuse in the neutral which then can leave the appliance still Live. Perhaps use a "Martindale" socket tester first and after you've finished.
GREAT TIP. The Martindale tester has now evolved, and is also manufactured by other companies. One design can now pick up 30 different faults! These testers are super cheap- a MUST HAVE! TKY
Enjoying your videos. We are having lots of work done at ours during a renovation. I don’t seek to learn electrical skills to do my own work. I seek to learn what should be done so I can question dodgy tradesman with some sort of background knowledge. Thankyou so much for posting.
By "getting the screws threaded" I think you mean CROSS threaded, which then strips the screw and often the lug. Much worse in plasterboard back boxes that seem more prone to cross threading.
This is great knowledge to show, it might make some DIY'ers to think nah it isn't worth it and just get a electrian in. But the ones who are braver know how to do it correctly and more importantly safely.
Great video. Only critique, you should not switch the mains switch off under load. Shut off all MCB’s, RCBO’s and RCD’s before shutting the Main Switch off. Also, do not switch the Main Switch back on unless all of the above is still off.
Explain the difference in meaning between off and OFF on and ON Your CORPORATE GOVERNMENT dog school failed to teach you and you failed to read and teach yourself and now you don't have clue Explain in which context the above words are used. Provide examples. My youngest school students know the answer.
Like the tip on getting a screw tap. I saw some electricians use a relatively cheap socket tester (about £12) so bought one. Also I've found having some slightly longer M3.5 screws than the ones supplied, handy for some backplates.
Nice video. Education is power. Some Pros will not like this stuff being shown, but I’m of the opinion that better to show how it’s done right than have some poor sod endanger themselves for no good reason. The DIYer is going to have a go regardless, so why not educate them properly.
Also... makes it safer and easier to work with for some subsequent professional in following years. Contrary to so many tradespeople who deliberately leave a mess for people who to work with later
I'd only add that when pulling the wires to make sure they are clamped, it is best to pull each wire individually (which he did). If the space in the box is limited I fit a deeper box rather than crush the wires, it saves fiddling around.
Having just finished refurbing a bungalow, I have a question for you Jordan. Have you tried engaging the services of an electrician? Never mind good or bad, just finding one that can do a small job? Electricians, plasterers and plumbers. Absolute nightmare to get any of them to do as they say they will and actually turn up on site. What’s more frustrating is I’m qualified up to 16th edition of the regs but can no longer do this stuff because I’m not going to spend thousands on kit for all of the testing and certification that needs doing now. The electrician I finally managed to engage (at proper money I might add) finished 5 weeks behind schedule which really ruined the timetables of all the other tradies on site. All VERY stressful, especially as I’m only a handful of miles outside your radius.
Tell me about getting plasterers in. I have a front room and half a hall way to do. I have given up for now. The worst thing was when two cowboys who I only knew by mobile phone number thought I would be stupid enough to pay a £1000 deposit for materials. How much God damned plaster were they going to buy assuming taking the deposit wasn't a scam of course.
I had, I will call him a so called electrician, employed by a builder to do a kitchen extension. Shortly after the work was completed I decorated the new and existing kitchen and loosened off the light switch to paint behind it and found the cowboy had screwed the face plate on with wood screws.
I have lived in a few countries....i am never surprised how people wire up their houses.... Sadly in Germany often in the same property the positive is sometimes on the left and sometimes on the right... Which can affect electrical goods purchased in the UK/Ireland. Good video as ever.
Checking the incoming socket to ensure you get the L and N connections correct to avoid reverse polarity is vital. So very important not to go by the photograph that you have just been told to take !
You can buy a cheap plug tester that makes an audible sound which is great when you're turning the power off at the consumer unit because in most situations you can hear it go silent indicating you've flipped the right switch. Obviously you'd check it with a proper tester but it can save some leg work.
I saw that to . Had to sit down and have a cup of tea ! Doubt I will sleep tonight with the worry . Oh yes I will because I’m not a total wanker like you .
Put a bit of tap and a note across the MCB to prevent switching back on easily, especially if the circuit worked on is for the kitchen. "She who must be obeyed" may switch it on again without warning, to get kitchen equipment working.
It's down to space we have some of the smallest houses in the developed world. New builds tends to be a bit better like above a door. Mine is under the stairs in my house which is an open area so isnr to bad to access.
@@wizard3z868yeh stupid next to a washing machine makes no sense but being the UK we tend to struggle with space. My mum old house had tumble dryer in the bathroom just struggled to find a better place.
I would recommend NOT installing USB sockets because the USB standards have changed numerous times and I have never found a faceplate socket with a high enough current rating to quick charge
They're crap. I hate USB sockets and I won't fit them until someone comes out with one that has a switch for the USB part. They're using power all the time the circuit is energised and they make testing a pain.
@@NigelMarston That's not a valid argument. Firstly because the socket can be changed easily to support later standards. Secondly, if you have USB charger in a socket that can deliver 2 amps at 5 volts it will charge any phone. Fast charging shortens the life of the battery. Thirdly, the standards don't change that frequently actually. The main reason for not using power sockets with USB charging sockets is the expected short life of the charger with it being in a confined space.
Got some lovely short wiring on my FCUs I'm putting in. But only because I've chased plastic conduit into my lovely 1950s solid concrete walls. Plenty of cable, but the excess pushes up/down neatly into the ceiling void above/ below them. I believe some companies (Schneider Electric for one?) make spacers if you want USB sockets into standard 25mm back boxes without all the extra hassle of ripping out the back boxes too. Just adds 10mm protrusion from the wall though.
Good advice, I honestly hate sockets. Trying to stuff rigid cables into a tiny box seems daft. Often the faceplate is virtually bulging trying to get it back on, especially when three cables are in it. Plus the fact the stress of the bundle puts on the screw terminals. I always put on the deepest back box I can. I always pull the cables hard after I tighten the screw terminal.
I like the tip about cutting a new thread. I had this issue the other day but thankfully the screw managed to cut the thread for me after a few tricky turns. If it had broken I’d have been in trouble as I’d just finished plastering and decorating the room! I did actually use an older megger tester to check the rcd despite not being qualified
Turn left first until you feel the exact begining of the thread ... nearly never damaged a thread (when it happened it was mainly because someone damaged it before me). This is especially handy when removing and putting back self tappers in soft materials avoiding to cut another thread instead of using the one that is already there.
another diy trick that we do in the states is called pigtailing instead of placing multi wires under one terminal(most devices in the states this is against manufacturer use) use a wago and have only one lead to the terminal less chance of a loose connection
@artisanelectrics also works great to extend short cables as well(the real reason I started to use wagos than after having to untwist earth's for testing another use ) now I'm comfortable with them to use all the time. A bit pricey though hard to be competitive but I do try to tell my clients I spend more for a more reliable job sometimes it helps most times they just want to save pennies (yes we still have and make them for some ungodly wasteful reasons lol)
Great Video with some very useful tips for DIY'er to do a safe and proper job. However the majority of the tools you described (and I have all of them except the MFT) are really not needed if the individual isolates the house at the consumer unit then does a like for like replacement. In this case the minimum required is a flat head screwdriver. One further tip to avoid the need to redecorate, take a stanley blade along the outside of the faceplate to break any paint attached to it and avoid it tearing when you take off the faceplate. Also rather than buy a 50 or 100m roll of cpc sleaving ask your sparky for some the next time he/she does some work for you as a couple of meters will last you a lifetime.
The sleeving is available in shorter lengths at all usual outlets in UK: Screwfix, Toolstation, TLC, CEF, B&Q. Local electrical suppliers usually happy to supply any length, especially if you buy other stuff from them. I have several diameters of earth sleeving to cater for lighting and power up to 4mm². Plus blue and brown over sleeve for lighting 2-way switch. DiY should be done by the book, even if a professional says "Don't bother"
Many years ago an electrician told me that another reason for the bare copper earth was to make it easier to split/open the outer sleeve. Expose ½" of bare copper, grip it with pliers and pull perpendicular to the cable. The copper core will literally slice open the outer sleeve.
@@AbbieMarchant "The copper core will literally slice open the outer sleeve." That's not why the CPC isn't insulated though. Its mainly cost. Its not really good practice to spit the outer insulation that way, not good for the CPC. I grip both live and neutral.
Personally I use a plug in socket tester with power still on with an audible tone, you can then isolate the socket from the consumer unit by listening for the audible tone to stop, save keep going back or ask someone to listen for you, then once the facia is loosened from the back box check again with the 2 probe tester. New install measure from corner to corner as a guide to cut the length of the cable. I agree never twist the earths together, main reason if ever there's a fault on the circuits easier to default find with a multi function tester.
The difference is that you aren't emerging from the washing machine, naked and soaking wet. Well, at least not tin the UK; we aren't that adventurous. Maybe it's different where you come from. In any event, standard sockets have been allowed in UK bathrooms for a few years, but a minimum of 3 metres away from any wet areas (basically showers and baths). That has recently been reduced to 2.5 metres. The principle is that you don't have people who are soaking wet handling something like a hair dryer. Less of a problem with RCDs of course, but the regulations were originally produced before they existed. Also, the placement of the CU next to the washing machine is a trifle off, but then the CU is in an earthed metal box so it's extremely unlikely that anybody using that washing machine is going to be exposed to live electrics. Washing machines also don't tend to throw water into the surroundings. If they leak, it usually ends up flooding the floor, not the walls. In any event, that's an unusual set-up, although I doubt it's dangerous.
@@TheEulerIDwhile you may be technically allowed a socket in a bathroom now you would have to have a huge bathroom to actually be able to able to fit one!
british house: washing machine is in the kitchen so you take your dirty clothes to the room you prepare food in and if you drop the clean clothes when you take them out of the washer they pick up any crumbs or bits of food you didn't sweep up earlier. As a bonus you can listen to the washing machine hum away while you make your dinner. European house: washing machine is in the bathroom. A much more sensible place to put a machine that cleans dirty clothes.
Always enjoy your videos. Any chance of doing a video where you demonstrate using a two pole voltage tester on the wiring inside a live socket? This would be to show what results the tester would come up with if the socket was correctly or incorrectly wired or if there was a problem within the circuit somewhere. The manuals never go into any detail about this.
My personal tip is to put the face plate screw into the the movable threaded lug first, then when fitting the second screw, the lug is easier to find as it does not move about. Do it this way as often it is visually harder to see the lug for the second screw as the socket is held close to the wall.
Either I am an absolute child and spent too much time with other adult children on site or you are also animals….the amount of ‘adult’ innuendos that I heard was incredible, made my day. 😂😂
“But I know you’re going to do it anyway” better to educate people in how to do it safely rather than pretend that nobody is going to try doing it. Same reason they have “safe spaces” for people to take drugs in.
Why? There are many basic jobs a reasonably educated person can do with the right tools and a little common sense. Just a little research can give you enough knowledge to replace a ceiling light or plug socket. Electricians are expensive and they usually can't be bothered with jobs like this unless it's part of a bigger, more expensive job. Mucking around with C.U.'s, rewiring, and running cables around is obviously (and legally) a job for a qualified professional but changing a socket or rose shouldn't be beyond the homeowner.
Legally you just need the work checked Completely wired my loft extension - got a sparky in to sign off (one ring continuity fault that needed my troubleshooting skills). Had to do some work on the 100A side at another house - again, sparky came and signed it off with one correction (I was one edition behind the spec at the time in terms of glands for the tails).
It’s now the norm for a fleet of commenters to fall over each other in the effort to be the first to point out some nugget of wisdom that they think the OP has missed. Funny how many people love to be “expert” critics in the comments but would never dream of creating expert content themselves.
Hi all, hope you enjoyed our latest video. If you want to get your hands on some of the equipment we used during the video, then there is a few links in the description for you to go look at. 😎
@artisanelectrics I like your content. Just have a question on this video and some feedback.
With how you have finished your safe isolation. Suggesting that you turn that circuit back on to prove your test equipment just after you have test for dead defeats the objective of proving dead. If using a know source to prove your test equipment you should be using a different source/ circuit. Hope that makes sense.
Is there a maximum required permitted distance where a washing machine can be fitted next to a consumer unit ? Just asking as I want to do the same.
Here in the United States all metal boxes need to be grounded you would say earthed and all ground leads need to be twisted together and crimped so they do not come apart.
You may want to edit your video, to mention, that not earthing the metal type backing boxes can result in the fixing screws for the front plate becoming live, this is even more dangerous, if the front plate used is of the metal type, as the whole plate becomes live, and mere contact will result in potentially a lethal shock even with the protective RCB in circuit.!!!’
Stay safe out there, from a old long retired sparks, thanks for the video, people do stupid things and learn unfortunately their last lesson!!!’
It’s what the Darwin Award was created for!!’ ຈل͜ຈ
.
This is one of those rare videos that properly explains why, not just "because regs" or "that's how I was taught". Much more convincing imo to the casual DIYer who might otherwise be tempted to bodge it. Well done!
I already like this video even only 10 seconds in! The attitude of "I know you'll do it anyway so here's the RIGHT way to do it." This is perfect! You'll never stop the DIYer from doing simple things like sockets so at least having good educational sources out there to try and keep them safe is a life saving thing!
We know people will do it anyway so we thought we would show people the safe way of doing it.
I really agree with that.
At least where I live (in Sweden) way too many electricians have the attitude of "don't mess with your electrical installation your self or you will die or burn your house down" - and even some sellers in hardware stores refuse to answare questions about electrical work (even though you can buy all the stuff you need).
That's because of our stupid laws.
But many of us don't give shit about those and I also read that like 50% of house owners have in fact done electrical work that's not allowed anyway (because even simple things like connect a washing machine to screw terminals on the wall, requires an electrician to do legally here) and very few people get caught (and most of the cases where someone have been, it's almost always illegal paid work or if they have done a bad installation on someone elses property, that have caused a fire or a similar thing - which is a whole other thing).
The other 50% is probably mostly people who really know nothing about electricity and would have an electrician do any work anyway. So this shows how dumb that attitude (and laws) is, as they will just contribute to making installations less safe than if information is spread how to do the work correctly.
@@Speeder84XLHaving written negatively about most electricians I've used and positively about diligent by the book DiYers, I have to support the shop that won't give advice. There are books, regulations that can be downloaded, and good UA-cam channels like this and effix. Shop is right to protect themselves from accusations of saying the wrong thing or someone doing wrong despite the correct thing they heard
@@cuebj That's true. I was refering to what I have seen in for example some chats and forums - things like "when I worked at a hardware store, I refused to answere any questions about electrical work as people shouldn't do that them self". Which sounds to me like those electricians.
But, now when you say it - it's pretty obvious that the stores (and the companies running them) don't want to deal with someone doing bad work and blame it on them.
Especially since out "electrical safety authority" (which is most likely heavily influenced by lobbyists from electric installation companies) have been on everyone selling electrical equipment already and forcing them to for example put up signs, "all electrical installations have to be done by an authorized electrician".
So, if there is for example a fire and someone blames it on the advice they got in the store, they would in fact likely get sued for causing it, by helping unauthorized people do electrical installations.
@@artisanelectrics I've been doing most of my own electrics since I was about 10. I'm now 68 and still alive with no more than a handful of belts to my name, so I must be doing something right. My father was an engineer and my next door neighbour when I was growing up was a sparky, so I picked up a lot.
As my username suggests, I've always been fascinated by test equipment, and have amassed a fair bit over the years, including no less than three MFTs (Fluke 1664FC, Megger 1552 and 1741..!) I've also taught myself how to use them, so although I'm not qualified, I do feel I have some idea what I'm doing.
Gotta love new builds .. the consumer unit next to the washing machine at the start of this video.. amazing!
I did wonder about that too😂
Worse. CU next to the drain outlet. So if there's a blockage the CU is going to get very wet.
Yep, and does that pass regs?
Those pipes often crack and piss out
That’s the first thing I thought 😂
Bet the house cost £250,000 too.
Thank you. That was a lot less harsh and a lot more informative that I expected. I've replaced many sockets, switches and light fittings in my house, and put in additional sockets as required (who thought that one single socket per room was enough in the 1980s?).
I always try to keep up to date with proper practices and safety and will call in an electrician for anything that I feel unsure about.
I agree about making sure the wires on the sockets are long enough. Unfortunately with my house cost came first and all wires had been installed as short as possible! I also like deep back boxes to give plenty of wiggle room for the wiring.
Some nice tips.
Interestingly as an industrial spark, I’ve often shuddered at the work of domestic sparks.
I’ve lost count of how many socket faceplates I’ve removed to find either excessively short cables, loose terminals or both.
The worst case I’ve come across was my parents shower installation. The shower had stopped working, when I investigated it for them the shower isolator was burnt out from a slack termination. It required a new switch and luckily in this case there was enough length to re strip some fresh copper.
It’s a pity not all electricians are of the same good calibre.
shower pullcords etc are a nightmare, as is 10mm T&E. Never enough room in a single backbox really. Although T&E is a terrible cable choice too. SY cable far more suitable.
Great job sir professional
The fella who previously owned our house had secured the earth in the socket terminal with filler.
Great video and great tip on re-threading the lugs but please use the correct term for the problem which is "cross threaded" not "threaded"
Noted!
I’m an electrical engineer. I have degrees and everything, I then followed on to do an apprenticeship in an electricity company. I would love to say all electricians are good, but in the three houses I have owned, I’ve found over 30 issues with the work “professional electricians” have done. From wiring extra sockets off a lighting circuit, to not bothering with earth connections onto metal light switches. It’s a shame no one can be trusted to do a safe job.
One thing I found in mine not really anything wrong I'm guess it's fine to bring wires through a joist but some of my light circuits come through the joist so if you want to fit a low profile light and need to pop a junction box up into the ceiling you can't. Pain in the arse as the one I was doing is right under the board for the old water tank somcant pull it up to then drop newmfeed down and can't really cut the ceiling as has asbestos artex.
@@HA05GER That asbestos artex is a right pain isn't it?
Such a stupid thing to say from an apprentice 'its a shame no one can be trusted to do a proper job'. Despite clearly having watched this video where t job is done properly u claim this - most bizarre. 🤦
@david-iandawson Well what do you expect when someone begins with "I'm an electrical engineer."? It doesn't matter which side of the Atlantic you're on, those idiots seem to think that carries weight to electricians in the field.
@@danieljadorie829 I totally agree. It's the arrogance that baffles me. To claim they know what they're 'talking about' shouts out to me their crappy character. Whilst moronic folk like this claim to be competent, u just know they'de sink at t first hurdle attempting to claim they can do t job of a qualified sparky who has experience.
We must be on t same frequency - no pun intended 😁😂😂😂😂
Some good points there, in regards to depth of the back box, as an alternative you can get spacers to go around the socket, effectively making them sit proud, some might not be happy with the look but it's a definitive alternative to having to excavate another 10mm of depth into your brickwork.
Yes Dave I am glad you mentioned the double socket spacer ,easily bought on Amzn. I am a retired electrician and I have some serious reservations about home owners working on wiring. I am sure a thousand sparks would agree that like me on removing sockets they have found often an amateur dangerous bodge-up mess. From incorrect under size cables and no grommets to multiple spurs taken off , broken ring circuits ( which an amateur would not look for) although Jordan has presented a clear informative vid the though of homeowners changing sockets makes my blood run cold.
@@garypautard1069 I couldn't agree more and it's not just the DIYers unfortunately.
In a previous property that i lived in (for about 12 years), I was surprised at the number of junction boxes and also choc-block connection block "spurs" and joints.
As it was a council house, i was fairly limited, but whenever contractors came in to do other work (such as adding central heating, new smoke/fire alarms, electric shower etc) I always managed to find and fix previous "bad practice" situations overnight while boards were raised and cables exposed.
If/when contractors had boards up for access that exposed existing wiring, I'd ask them to just leave them up overnight seeing as they'd just need to lift them again the following day. Then I'd identify whole masses of spaghetti and various types of junction (often with no earth sleeving), as well as multiple spurs from a single box. Then I'd either reroute cables or replace whole sections to recreate a single ring without any junction boxes. Securing cables, adding sleeving and removing as much of the tangled spaghetti situation as possible.
When the contractors completed their work, the test results were always better than the readings from before they started.
There was only one thing that i missed, which was the pull switch for the shower. When they installed it, they siliconed the switch and i didn't want to break the seal. 18 months later, the shower stopped turning on, so i opened the switch and discovered badly charred wires, the live just slid straight out - obvious that the terminal hadn't been tightened, causing sparking every time the switch was used. There was so much damage inside the switch, molten plastic, black charred wires and contacts, it's a wonder that it hadn't caught fire.
Even though there was plenty of space available in the attic directly over the switch, whichever electrician did the install, cut the wires extremely short. When i replaced the switch, i ended up moving it 6" closer to the bathroom door so that i could trim the burnt cable and have enough good/virgin wire to make good connections. (6 years later, when i moved out it was still in perfect condition).
@@garypautard1069 Just been working on the electrics of my present house which dates back to the mid 80's and some of the original work done by so called professional electricians is shocking, excuse the pun. It's been the same in two other houses I have owned. Hopefully, standards are higher today, but sadley there are cowboys in all trades...There some jobs I am happy to do on electrics around the house, while there are others I prefer to call in a qualified spark...I have had quotes from one of two over the years that I have rejected because of the way they intended to do the job. I remember one who wanted to spur an outside light and an outside socket direct off the house lighting cct rather than put a separate cable back to the consumer unit which is what I actually wanted. The consumer unit had space in it and was located in a convenient place meaning there would have been little difference in the cable runs. The only added difficulty was that the guy would have had to work in the consumer unit which he seemed reluctant to do.
@@garypautard1069 Don't paint us all with the same brush though please. Those of us who watch videos like this are educated, all for the better. I have had all of the work I've done in my home over a period of 40 years checked and certified by a qualified and reputable sparkie who was very complimentary. His only negative criticisms were of some of the original builders' work which I had not touched.
Great video. Another tip would be to check if there are rubber grommets installed in the back box. I have seen so many without them. Worth adding if they are missing.
Very important to make sure the terminal screw is touching the copper, not the outer insulation 👍
I actually use a sharp needle on the end of one test lead to check continuity between the terminal screw and the wires by pushing the needle through the wire insulation as close to the terminal as possible. And yes it will leave a tiny hole in the insulation but so small as to be irrelevant. It absolutely confirms the wire is connected to the terminal correctly, very important for a ring circuit which might otherwise be broken if one wire isn't actually connected properly.
Particularly important not to screw down on the earth sleeving
If the cables are too SHORT
What are the options
A very clear and concise article apart from one thing. Trying to get a sparkie who is willing to do a home visit just to fit or test a single socket. It aint going to happen. If you can get one they will charge a fortune. I'm lucky I have a working knowledge of this sort of thing and the appropriate tools but luckily my neighbour and friend is a tutor at an electrical college and so he's fully up with the regs and gives me good advice in advance of any projects I have and has got me out of shtuck more than once.
My mate needed a 30 year old bathroom light replaced after it stopped working due to the bulb contact points breaking down. His local spark wanted £200 for what was to him 10 minutes and he lives in the same street! He didn't even need his van! I did it for the cost of a box of wago connectors.
A lot of these vids all state that if you can't do the job or don't feel confident about it call a professional. Sound advice but getting one? Good luck. 👍
When I moved in to my last house, the garage was powered by a bit of trailing 4mm that the previous owner had installed. I'm very comfortable around electrical systems - I'm an electronics repair specialist - so I rewired the entire garage, including fitting a small consumer unit to separate out the boiler, lights and sockets.
Getting an electrician in to check the work was an absolute nightmare; I wasn't comfortable using the new accessories until they had been checked by a professional, and in the end (after over a year) I managed to swap 'work for work' and fixed an 1662 (electrical testing unit) in exchange for the work.
I'd have had no issue paying for the work to be checked - even above what would be a fair amount of money for the work - but unless you're offering them a job where they can charge ridiculous amounts of money, my local electricians just don't give a damn.
I can't imagine how frustrating being in a similar situation would be for someone who's taken the time to learn how to, and then carried out their own work, only to hit a roadblock because of lazy/avaricious sparkies.
You are both absolutely right. I can do simple stuff but cannot do PAT testing or EICR reports obviously but getting anyone to even ring back is a nightmare. They all complain on these U tbe vids about "amateurs" but not returning calls because they cannot be bothered is just rude and pathetic.
@Do you find so called mates or neighbours, then say 'oh that didn't take long' and hand a token fiver or nothing at all, yet often they're willing to pay a professional a couple of hundred for same job. I gave up being kind but rather late in life. I find it hard to say no to help others.
@@DavidMartin-ym2te I got myself qualified to do PAT (not PAT Testing please, that says Portable Appliance Testing Testing, which is silly..!) and have done all the equipment in the house. It's amazing how many things there are, you don't realise until you go through them..!
Just seen your note - sorry about the tautology!
@@TestGearJunkie.
Out of all the socket clips I have watched the re threading tool is a new one for me, Thanks for this vital info.
This is one of those rare videos that really explains _why_ to do this or that, not just "because regs". Regulations are important, but they themselves exist for a reason, and these reasons are imo more convincing to a DIYer who might otherwise be tempted to bodge it. Well done!
Washing machine waste pipe right next to the consumer unit 😮 lovelly
Had the same thought !
Me too 😊 Bet it was placed on purpose so viewers can comment. That will spike the insights
There is nothing wrong with the washing machine where it is. If it has been installed correctly.
I clocked that too 😂😂😂
Amateur comment But the hose goes directly into pipe so no water will come out though?
Before taking sockets or light switches off, loosen the screws 1 turn and tap the socket with your screwdriver handle. It will crack the paint seal, preventing chunks of paint breaking off.
Thanks for the information, can be helpful for people to learn
nice tip thanks
I usually run a Stanley knife around the outside to avoid peeling the paint or wallpaper off. Sometimes a tap is enough but sometimes not.
@@craigchamberlain I use a knife. especially in new builds where the faceplates are often siliconed around.
Never tap the socket, water and electrics don't mix.
Fantastic positioning of the washing machine drain next to the consumer unit…
That's not really an issue. Look at where any water will be. Not anywhere near the box.
Thanks for this video Jordan , this has given me the confidence to install my own 3 phase 😂
You got this haha
I did not like how close that washing machine waste pipe was to the fuse board
When fitting the socket back into the box, it's important to check that as you bend the wires, none of them are directly behind the face plate screws.
It is possible to tighten a face plate screw through a conductor that is immediately behind it, thus creating a short.
Thx for the detailed video. Most helpful
I have done many of these in my house just using Google search to remind on colours and common sense - and did everything on your list (except earthing the backbox - I was happy with the risks relying on the screws to cover that)! So yay for I guess my Dad who must have taught me this stuff when I was growing up - I think he must have instilled the right principles/practices when messing around with electrics. Cheers anyway for the video! Another simple way to test for live is to grab a phone charger: have it charge your phone before turning off the socket ring main, then turn it off. If it stops charging - it's probably the right ring main/circuit. Do this process twice and it's almost certainly the right ring main. I recently bought a Klein tester to triple check the cables too, so slightly disappointed to hear they're not always accurate. But I figure it's better than not doing a wire test as a triple check. A DIYer isnt going to spend the presumably £800 or so for those posher testers....
Are you having a laugh? If you're being serious, let me give you some advice....don't go near electrics. And if you persist, invest in an audible socket tester.....forget all that phone charger stuff.
A screwdriver with a light is more than enough. 🙂
First, check that the light is on, then turn off the main or line fuse and check again. It's not rocket science. 🙂
I was a bit surprised at the back box not being earthed. I was told by a electrician the it was a requirement. I went around the house each time that i decorated a room and added an earth to the back box. Then I am confused why plastic dry lining boxes have an earth terminal.
Over the years I’ve had tons or cross threaded back boxes. I got a rethreading tool (taper tap) and never had to use it since…… bugger 😂. Nice video Jordan.
Better to have it and not need it than need it and not have it.
@@neilturner6654 I still haven’t used it. I’m going to leave it at home one day and I bet you that’ll be the day I need it 😂
Great video, I think its worth mentioning that when isolating at the fuse box, not all isolation points are double pole, so you still have a potentially live cable, the neutral. And as you know because its potentially live, current will flow between the neutral and earth, if there is an rcd this will trip if not, you get a tingle! I would always recommend a DIY'er to switch the main switch, or call an electrician. Its nice to see that in some installations now in the UK people are using double pole isolation (rcbo).
An RCBO is a device that combines MCB and RCD functionality. It has nothing to do with whether it is dual pole or not. Both are available, but not from all manufacturers. Dual pole breakers are convenient for some type of testing, but they do not add much to safety in countries where circuits are routinely polarised. If there is a requirement to isolate both line an neutral, then there is always the main switch. That cuts off all the power, but as I mentioned, it is primarily convenience, not a safety issue.
@@TheEulerIDany residual current device is at least double pole(L+N), otherwise it wouldnt even work in the first place.
@@zaxmaxlax Whilst it is true that RCDs (and therefore RCBOs) have to have both line and neutral feeds, poles refer to the breaker part, not the detector (and switches in general). In my case, the RCBOs in my CU only break the phase line, not the neutral line (which is what the overload function does too). There are diagrams on every RCBO showing whether it breaks both lines or not. Mine most definitely only breaks the phase line.
So, no. You have misunderstood the terminology. Poles refer to anything that breaks or switches circuits, not to detection devices. Stand-alone RCBOs are most often single pole, as are most MCBs, at least in the UK. RCDs will almost invariable switch both poles.
A lot (most really) of rcbo's are still single pole
@@zaxmaxlax they are double pole in that sense but alot still are still only single pole switches and don't isolate neutral
Love the tip to re thread the back box holes. Sometimes I've spent as long refitting the cover as I have replacing a socket.
I can add a tip I learned the hard way. Make sure you don't trap any of the wires when putting the face plate back. I accidentally pinched a neutral wire between the end of the face plate screw and the back box. The insulation wasn't split so there was no direct metal to metal contact, but it was enough that every time a load was switched on, on the same circuit, the trip would shut it down.
Thanks for the tip!
VERY EASY TO DO!!
I've just added a separate comment about this problem
HATE 25mm deep back boxes!!
The more important reason not to twist the cpc's is that they will still show when testing that they are connected even though they may have fallen out of the socket itself. The earthing of the back box can be essential if you do not have a fixed lug that the screw goes into.
Ive yet to find a socket screw connection block that will safely hold three conductors without tightning to the point of crushing the conductor (the screw usually only impacts and holds 2 of the 3 securely) so in the case of a ring socket which is feeding a spur I twist the last 15 mm of so of the earths.
Surely testing the earth through the socket is a required test after changing one in the UK. Even a basic plug in tester will pick up that there’s no power across the phase earth if the conductor have come out the back of the socket.
@@pncampbell The MK sockets with 'Wago' style connectors are good for this, there are three connectors for each of the L, N and E terminals.
I'm confident to undertake tasks like this and my working practice is that I have passed all your advice 100%, I'm super cautious with electricity. As an very experienced senior Architectural Technician, the one bug bear I have is front plates not being level. I happens far too often, mainly by apprentices, their gaffer should take much better care in teaching the apprentice the correct working practice. I saw a front plate and back box 15mm out of level 4 months ago. The guy who owned the company was on site, I pulled him about it and he thought is was funny!!
15mm!! That has to be a record over such a small distance!! And there's me making sure the spirit level bubble is in the middle of the black lines as there is always space each side.
The consumer unit in the video would benefit from being out of level by a few mil, for when that washer drain pees water all over it! At least some of it would drain away...
Good thing you‘re emphasizing the importance of using a proper voltage tester and not just one of those lying pens 👍
Thank God, I started watching the vid, saw the volt stick and thought, oh dear, oh dear. Fortunately things improved 😊
When I checked replaced some sockets recently in my '2004 new build' home, with the entire house wired by the George Wimpey spark, I found every socket had the CPC's twisted and sleeved by the professional!
before the current fashion for EICR's, many installations in the 60s and 70's had twisted earth wires on the rings. And digitial testers were yet to be invented. Our family's electrician had an AVO 7 and a neon screwdriver, a wind-up megger for tricky tests and a Vauxhall Viva with a ladder on top.
Worst thing I ever found? A domestic socket in an extension, on a ring, each end of the ring fed from a different circuit breaker. The householder was pretty proud of his wiring 'skills' too! I very nearly walked away from that job but I persevered and persuaded the guy to pay me to do a full installation check. That the threw a few more faults like poorly connected equipotential bonds to the service pipes but nothing too major. I put another half turn on pretty much every screw terminal though (with my calibrated torque screw driver)
Love watching those videos. As I watch videos from people around the world about electrical stuff, it's funny to see the differences. I'm from Germany. You wouldn's see something to screw in a socket over here. So nothing to get loose over time and cause sparks. But I do like the buttons you have on each socket. Also a main switch is not mandatory over here in the distribution boxes. It is mandatory in the main distribution though nowadays. But don't expect that in older installations. Usually an RCD will do that job if present (again, depends on how old that stuff is). When we took over our house, they only way to power down the complete installation was to pull the NH fuses. Worst videos about electrical installation usually are videos from the US. Their stuff looks dangerous compared to European standards. In regards to cable colors. We use the same as you do. If you find something old from the 60s, red might be earth, neutral gray and black and blue would be live. So if you see red cables over here, be vary careful what you conned to what.
What about Italy? Twisted conductors under a thimble connector, no form of EICR so the installation is never tested and relies on faultless original execution. Live is grey, black, brown, or red even in a single-phase domestic installation and there seems to be no consistency as to which colour live is used for what.
Very interesting.
I know how to wire north american outlets and so many differences.
One old tip that still works well, plug a radio in the outlet when you are at the breaker panel. You know you've got the correct breaker when the radio goes silent. When you are dealing with old houses with poor labeling of circuits it can be a lifesaver to not have to run back and forth to the breaker panel.
Test properly after but it's a good first step.
i've used a lamp before but something that makes a noise from another room makes a lot of sense. cheers
Got some (decent brand) faceplates from an ebay seller and delighted to find they threw in 2ft of earth sleeving. made me think that for DIYers this should be normal rather than an exception.
After isolating, the first thing to do is carefully run a sharp blade around the circumference of the socket. Saves it sticking and pulling paint etc. with it. Hopefully stops the other half recommending redecorating!
Worth it if you weren't the last one to decorate, but I'd go further saying first step is to make sure the sockets etc are loose from the wall and paint allowed to dry properly in the first instance. I do hate it when lazy decorators paint or paper up to sockets and switches instead of doing the job right first time.
Im am 53 years old. i qualified at 23. I have not done much domestic work for years (tended to spend more time moving furniture than working, and then theres the customers🙄) but i can honestly say i have never, ever used a spirit level when changing a socket, thats a level of dedication i never managed to reach!
I am sure you are a very dedicated individual
To be honest, after 10 years I trust my eyes more than an apprentice with a level
@@artisanelectrics In fact, if the socket is close to a ' not quite horizontal' skirting board, it should be installed parallel - otherwise it will look very odd!
Good to see the waste water outlet of a washing machine right next to the consumer unit.😀
Wow what a video you shared there. It was really eye opening to see how many little mistakes can happen when you're swapping out sockets at home!. Your pointers are super useful and will definitely come in for preventing any mishaps, down the line while dealing with electricity work in the future so thank you for sharing such valuable advice with us all!
If you're wiring up an all metal light fixture on the ceiling, make sure that the switched live doesn't get smushed between both halves of the fixture.
I've done that in the past and I was glad I had grounded the light fixture, as the result was blindingly spectacular. And loud.
Many years ago a neighbour asked me for help fitting a metal ceiling light fitting. He knew it should be earthed but there was no earth cable. I assume for some reason who ever re-wired the 1930s house just cut the earth wire off. There was no slack to pull any cable through.
I watched this again before replacing a double socket with built in usb in fhe FiL's flat. The wiring is from the early nineties.
The wire tails are imo way too short. It made securing a bit awkward. The earths were twisted together so I separated them and used some extra sleeving.
Thankfully all went back and tested well.
The dodgy socket was a gb fitted by a local oddjobber during covid. I replaced it with an MK one.
Thanks for the tutorial.
I am so pleased to hear you stress about proving the circuit you are about to work on is beyond doubt … dead, verifying you see it switch off as you knock the breaker off - remembering someone could have reversed the L and N connections too! Breakers can and do fail (older mcb and mccbs may not be positive indicating) and sometimes circuits aren’t wired as you might expect or the Reg’s dictate. You missed stating ensuring that everyone who may be in the vicinity knows the circuit must remain dead and must not interfere with anything until you give the all clear (lock off and tag - would be the ideal), verbal, visual/ signage. Use the right tools too - cutters for cutting only, wire strippers for stripping insulation. Check copper not kicked at the strip point when removing insulation.
Not a fan of looping the end of the stripped wire as you stress the copper on such tight 180 degree bends, if it’s clamped on the return bent end and not the straight copper then you are passing current through a reduced cross section and thus derated cable on the bend! In my opinion always better to keep straight and ensure conductors are seated correctly in the clamp. I always have a separate earth back box to the socket (ring earth paired on the other earth connection - standardised on double sockets so can do) that covers you where the box screw threads strip or are loose and could become live. In machinery and associated cubicle/ panel building wiring (to EN 60294-1) you are not allowed to use any securing/ mounting/ fixing screws to be used as an earth - the earth has to be a separate stress free connection. So still surprised wiring Reg’s have not caught up and don’t dictate domestic sockets are structured to ensure this best practise. Above all do not rush, check what you are doing - professionals make mistakes when they rush or get distracted too! Good to see your wire pull tests on individual connections. The devil is in the detail, well done.
But he said doubling it over not to have double thickness, but to take into account that only a single wire is being put into the terminal,
So either you have a single CPC going into the terminal, or you have a single and another wire (doubled over), which basically means two wires and I presume most likely better grip, and even if the bend breaks, it's still one/two wires which was the intended purpose.
Watching this as I have 2 switches that wont push in anymore rendering the sockets useless. You've scared me into getting an electrician now and ill be watching their methods. nice video, thank you.
May I humbly suggest that as an electrician, you may not want to be wearing your wedding ring while working. There are too many places/times to have that metal interfere with your work protocols : Bumping into something live, getting caught on any kind of protruding wires/metal/construction etc. Any kind of jewelry was banned from anyone working construction of any kind in my company. Rings, necklaces, earrings, etc. were all required to be left at hime.
Does a ring add any more risk? If you were to bump into a live wire with a ring vs the skin on your finger you’ll get a shock regardless right?
There is indeed a very serious risk resulting from wedding rings, metal bracelets, metal watch wristbands and similar when working around circuits with large batteries: if a short circuit is created by the ring/bracelet, the ring/bracelet may get welded and become incandescent, cutting your finger/wrist or at least causing very serious injuries. This is the reason why I never wear my wedding ring or watches with non-plastic wristbands.
Yeah ok… that ring will make all the difference 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
It is a very good point, I remember years ago my grandfather got his wrist watch across the positive of a car battery and the clamp holding it down. Obviously there was no risk of electrocution but a very large current quickly heated up the wrist strap causing a bad burn. Even extra low voltage systems capable of delivering high currents can be dangerous
I agree, I'm not married but my boss (who was) always left his wedding ring at home. A band of gold, one of the best conductors, will make much better contact with the skin than just brushing past a live wire with the back of a knuckle. You tend to sweat under a ring as well, just to make the contact better.
Great video - well explained thankyou. I'm a keen DIY-er and have changed many socket fronts. I recently added a double socket spur of an existing double on the downstairs ring. I found the existing socket didn't have a cpc to the back box - so added it in and did the same to the new socket.
So to my mind I've made a better job and improved the installation as a DIY guy - who's not under time pressure, than the professional who might (and did) cut corners to save time. Btw - I would only ever mod existing circuits and never run new before someone reaches for the wooden spoon ;).
Excellent point about DIY not under time pressure, except from spouse! Trouble is, you can offer a professional a bit extra to take a bit longer but their instincts, honed by quoting low to match low expectations of most domestic customers, override your offer so they still do quick sloppy work!
Just to add there were no grommets on the existing steel box - or sleeving on the original cabling either ! I added them.
Make sure there are grommets in the cable entry holes in metal backboxes. If you start a job like this and realise you don't have any grommets you're definitely going to 'conveniently forget' about them.
It's easy to fit a grommet after the event, and that's just to run a sharp knife through it and the you can fit it over the cable and put it home. There's not danger of touching the cable touching the metal back box as the ends will be pushed together. It's also a useful retro-fit as many back boxes did not have grommets installed in past years. Saves having to disturb the connections.
Nice sensible video, I too hate twisted wires especially into the live/neutral terminals, they always come loose.
Its also worth having a 'Socket Outlet Tester Receptacle Tester with Voltage Display Automatic Electric Circuit Polarity Voltage Detector' to double check the wiring is connected correctly in the socket.
Now we know who buys their tools on aliexpress 🤣
Great idea having that "'Consumer Unit"', as you call them over there in the UK, next to a washing machine drain. Asd a Sparkie, that would have sparked my interest straight away. I personally would make them move it or I'd put in defect notice on the property.
Rubber grommets around the wires where they come through the metal back box. I'd have put that on the list. Tight wires against sharp metal might cause the wires to wear through if stretched. Also, you might need to buy longer screws if replacing the back box. And, very importantly, make sure nobody in the house could accidentally turn theConsumer Unit back on. And tell people what you're doing so they know why the power has been cut. In a family house where you're the only adult going near that's ok, but on a job with other people working there it's an obvious issue and it might need locking closed.
Grommets are nice to see & good working practice but not a requirement. So you cant really put it down as a customer mistake. & no doubt same as myself you've seen plenty of so called proffesionals that can't be arsed to use them.
I like to have a light switched on and plugged into another socket on the same circuit.
Light goes on - > stop work.
I used to suggest to sparkies I worked with to take the fuses from industrial switchboards with them whilst working on jobs. I know of two occasions where people have seen fuses left on the top of a board and “helpfully” put them back in. It’s the most silly mistakes that can kill the sparkie, always protect yourself first.
Times have changed re safety over the last forty years for the better, but an idiot today can still kill you just as effectively as they did years ago.
@@ashleybignell2366I always pull up lack of grommets when I'm installing thermostats. Imo it's a faulty install... Doesn't take much to fix
Shows I am getting old. I was doing job or other and had the consumer unit switched off. Finished the job but for some reason didn't switch it back on. Probably got interrupted. Later on for the life of me I couldn't work out why the kettle was taking so long to boil. It did eventually sink in.
I love the fact that your number one emphasis is SAFETY.
Is that drain pipe next to the consumer unit legal or even a good idea?
Not a good idea. The pipe can build up silt over time and back up during a drain cycle. Been there, done that, but not a couple of inches from the mains!
I had an electrician come round to change sockets, and he did it with it still live. I told him to switch off the power but he seemed confident. I don't know if he was wearing some special clothing like they wear when working on pylons, but as far as I know, he's still alive.
If he came here and tried to work live he'd be out the door before he'd got the tools out.
One important thing missed. After proving dead ensure the cb is prevented from being re-closed so someone doesn’t come and switch back on while you’re working on it. Or at the very minimum tell everyone what your doing and not to switch it on
Also you should have a proving unit for your tester,
Sticking the fuse in your pocket is just a distant memory now…
@@NowInAus Not for me, although I’d need much bigger pockets 😏
Just modernised and added some new sockets on our home- an ex council house from 60s. Our main issues:
-Shallow 16mm back boxes needed to be replaced by 25mm
-Earth connector in 1gang metal back box was directly behind the screw lug
-No grommets on back box meant the mains wires had been worn to bare copper
-some VERY tough bricks to chisel into to allow for deeper boxes
I also once repaired a faulty light pendant- I turned the lights breaker off but the other lights stayed on, they had been wired into the fire alarm breaker!
Also if you reverse the live and neutral the fuse will be on the neutral. It can cause various risks like it can blow and leave voltage on the device or in case of ground fault it will be bypassed.
Good point. I was thinking of posting the same comment.
Tips for gettting the machine screws back in would be good. Some faceplates come with really short screws, so if the lugs are deep and you don't have spare longer screws, getting them in the holes can be tricky. I've been known to use cocktail sticks to get them aligned!
I added a pack of long screws to my tool box a long time ago.
I worked at an Electric blanket factory many years ago; one colleague suggested we all go to his gran's house for lunch. On entering the living room, we found his gran lying asleep on the sofa wrapped in an electric blanket; I stepped on the carpet, and there was a huge bang followed by a large hole in the carpet. His gran awoke as the blanket smouldered; she was okay. I checked the power had gone off and lifted the carpet. To my shock, she had extended two different gauged wires with sellotape. She did not have a plug, so she used the classic match sticks to hold the wires in the holes. It's not a good advert for the Electric blanket.
Good grief! On the other hand, you nearly saved on cremation costs...
Brilliant little video. Thanks. Confirms how this DiYer has done such little jobs for 50 years
My tip would be don't assume the wiring is as you imagine and test frequently for isolation. I gutted our house before a rewire but had the juice on for lighting etc. Entire house was on 3 old wire fuses (no MCB,RCD etc). Heating was via economy 7 night storage heaters isolated via a crusty old switch. Flipped the switch, did a DVM check to ensure no juice, removed the first storage heater and isolated the ends. Removed the second one, isolated the ends- on a roll! Unscrewed the power from the third, for some reason the dangling wires sparked my spidey senses- stuck a nice long metal screwdriver across the L+N- massive bang (though even that didn't trip the fuse). Turns out some genius had wired the last storage heater as an unfused spur off the ring circuit for the sockets. To this day not sure why I thought of "testing" it. Scary buisness. In my mind, an isolation switch labelled "night storage heaters" should isolate anything in the house purporting to be a night storage heater. Lesson learned. Other than the 3 wire fuses there would have been nothing other than the DNO 100A between me and the national grid.
When my sister-in-law rewired her parents' old house, the electrician found lead pipes with squashed ends of just poking out of the walls where the gas sconces had been; they were still attached to the gas main! I guess they had become redundant in the 1930s. It had been a council house until the 1980s.
Rewirable bs3036 are notorious for their large instant breaking capacity, even a 100a 1361 cutout fuse won't blow instantly at 100amp ,
Good informative video , a tip is to make sure the the wire in the socket are not behind the face plate screws as sometimes there can be upto 6-8 wires in the back box if it's a ring main with a spur coming off it.
Reversed polarity isn't "just" for the isolator ( switch). The fuse is always in the Live so the plug top properly wired will only "blow" the fuse in the neutral which then can leave the appliance still Live.
Perhaps use a "Martindale" socket tester first and after you've finished.
GREAT TIP.
The Martindale tester has now evolved, and is also manufactured by other companies.
One design can now pick up 30 different faults!
These testers are super cheap- a MUST HAVE!
TKY
Enjoying your videos. We are having lots of work done at ours during a renovation. I don’t seek to learn electrical skills to do my own work. I seek to learn what should be done so I can question dodgy tradesman with some sort of background knowledge.
Thankyou so much for posting.
By "getting the screws threaded" I think you mean CROSS threaded, which then strips the screw and often the lug. Much worse in plasterboard back boxes that seem more prone to cross threading.
This is great knowledge to show, it might make some DIY'ers to think nah it isn't worth it and just get a electrian in. But the ones who are braver know how to do it correctly and more importantly safely.
Great video. Only critique, you should not switch the mains switch off under load. Shut off all MCB’s, RCBO’s and RCD’s before shutting the Main Switch off. Also, do not switch the Main Switch back on unless all of the above is still off.
Explain the difference in meaning between off and OFF
on and ON

Like the tip on getting a screw tap. I saw some electricians use a relatively cheap socket tester (about £12) so bought one. Also I've found having some slightly longer M3.5 screws than the ones supplied, handy for some backplates.
Nice video. Education is power. Some Pros will not like this stuff being shown, but I’m of the opinion that better to show how it’s done right than have some poor sod endanger themselves for no good reason. The DIYer is going to have a go regardless, so why not educate them properly.
That is what we thought, better teach people then pretend it won't happen
Also... makes it safer and easier to work with for some subsequent professional in following years. Contrary to so many tradespeople who deliberately leave a mess for people who to work with later
this is one of those videos that properly explains why it is so expensive to do a socket refit.
Rethreading the metal box lugs is a useful tip - I didn't know you could do that! Thanks.
You can’t it’s against the law .
Why??
@@tonywright8294bullshite.
@@tonywright8294 As asked below, if it is illegal to rethread the metal box lugs why would Mr Artisan Electrics recommend it??

I'd only add that when pulling the wires to make sure they are clamped, it is best to pull each wire individually (which he did). If the space in the box is limited I fit a deeper box rather than crush the wires, it saves fiddling around.
You can also buy spacer frames which allow the socket to sit proud. That can give you wiggle room.
But they make your house look like a 70s caravan!
Having just finished refurbing a bungalow, I have a question for you Jordan. Have you tried engaging the services of an electrician? Never mind good or bad, just finding one that can do a small job? Electricians, plasterers and plumbers. Absolute nightmare to get any of them to do as they say they will and actually turn up on site. What’s more frustrating is I’m qualified up to 16th edition of the regs but can no longer do this stuff because I’m not going to spend thousands on kit for all of the testing and certification that needs doing now. The electrician I finally managed to engage (at proper money I might add) finished 5 weeks behind schedule which really ruined the timetables of all the other tradies on site. All VERY stressful, especially as I’m only a handful of miles outside your radius.
Tell me about getting plasterers in. I have a front room and half a hall way to do. I have given up for now. The worst thing was when two cowboys who I only knew by mobile phone number thought I would be stupid enough to pay a £1000 deposit for materials. How much God damned plaster were they going to buy assuming taking the deposit wasn't a scam of course.
All screws are threaded. The term to use if the threads are not engaged/meshed properly is cross threaded.
or 'stripped' 'non existent'
I had, I will call him a so called electrician, employed by a builder to do a kitchen extension. Shortly after the work was completed I decorated the new and existing kitchen and loosened off the light switch to paint behind it and found the cowboy had screwed the face plate on with wood screws.
I have lived in a few countries....i am never surprised how people wire up their houses.... Sadly in Germany often in the same property the positive is sometimes on the left and sometimes on the right... Which can affect electrical goods purchased in the UK/Ireland.
Good video as ever.
Checking the incoming socket to ensure you get the L and N connections correct to avoid reverse polarity is vital. So very important not to go by the photograph that you have just been told to take !
Well it should surely have L and N marked on it by law I should think .
Well the photo will show you which colour connects to which letter, so it has a use.
@@Thurgosh_OG That as well .
You can buy a cheap plug tester that makes an audible sound which is great when you're turning the power off at the consumer unit because in most situations you can hear it go silent indicating you've flipped the right switch. Obviously you'd check it with a proper tester but it can save some leg work.
one thing that worried me was the proximity of the washing machine outfloww to the main board , just seems a bad idea.
I saw that to . Had to sit down and have a cup of tea ! Doubt I will sleep tonight with the worry . Oh yes I will because I’m not a total wanker like you .

Put a bit of tap and a note across the MCB to prevent switching back on easily, especially if the circuit worked on is for the kitchen. "She who must be obeyed" may switch it on again without warning, to get kitchen equipment working.
i love how you brits place your c/u in the most in accessible places than say how great and superior your methods are over the west lol
Yes
Some places are strange, but I have never lived in a house where it isn't inside a cupboard that is easy to access.
It's down to space we have some of the smallest houses in the developed world. New builds tends to be a bit better like above a door. Mine is under the stairs in my house which is an open area so isnr to bad to access.
@HA05GER lol same here in my area of the states but really cram a washer of all things next to it 😅
@@wizard3z868yeh stupid next to a washing machine makes no sense but being the UK we tend to struggle with space. My mum old house had tumble dryer in the bathroom just struggled to find a better place.
I and many others clearly watch too many of your very helpful videos. 0 mistakes here.
I would recommend NOT installing USB sockets because the USB standards have changed numerous times and I have never found a faceplate socket with a high enough current rating to quick charge
They're crap. I hate USB sockets and I won't fit them until someone comes out with one that has a switch for the USB part. They're using power all the time the circuit is energised and they make testing a pain.
@@NigelMarston That's not a valid argument.
Firstly because the socket can be changed easily to support later standards.
Secondly, if you have USB charger in a socket that can deliver 2 amps at 5 volts it will charge any phone. Fast charging shortens the life of the battery.
Thirdly, the standards don't change that frequently actually.
The main reason for not using power sockets with USB charging sockets is the expected short life of the charger with it being in a confined space.
Got some lovely short wiring on my FCUs I'm putting in. But only because I've chased plastic conduit into my lovely 1950s solid concrete walls. Plenty of cable, but the excess pushes up/down neatly into the ceiling void above/ below them. I believe some companies (Schneider Electric for one?) make spacers if you want USB sockets into standard 25mm back boxes without all the extra hassle of ripping out the back boxes too. Just adds 10mm protrusion from the wall though.
Can I ask what the electrician's view is on using the rcd test button on a socket tester to identify and turn off the ring main?
Good advice, I honestly hate sockets. Trying to stuff rigid cables into a tiny box seems daft. Often the faceplate is virtually bulging trying to get it back on, especially when three cables are in it. Plus the fact the stress of the bundle puts on the screw terminals. I always put on the deepest back box I can. I always pull the cables hard after I tighten the screw terminal.
I like the tip about cutting a new thread. I had this issue the other day but thankfully the screw managed to cut the thread for me after a few tricky turns. If it had broken I’d have been in trouble as I’d just finished plastering and decorating the room! I did actually use an older megger tester to check the rcd despite not being qualified
Had a similar issue and tiles over the box luckily my work carried 3.5mm nuts so just attached one behind the original thread.
Well that’s a worry of my mind ! Phew
Turn left first until you feel the exact begining of the thread ... nearly never damaged a thread (when it happened it was mainly because someone damaged it before me).
This is especially handy when removing and putting back self tappers in soft materials avoiding to cut another thread instead of using the one that is already there.
If it's the thread on the adjustable side that's broken you can rob one from another backbox
another diy trick that we do in the states is called pigtailing instead of placing multi wires under one terminal(most devices in the states this is against manufacturer use) use a wago and have only one lead to the terminal less chance of a loose connection
Thanks for the tip!
@artisanelectrics also works great to extend short cables as well(the real reason I started to use wagos than after having to untwist earth's for testing another use ) now I'm comfortable with them to use all the time. A bit pricey though hard to be competitive but I do try to tell my clients I spend more for a more reliable job sometimes it helps most times they just want to save pennies (yes we still have and make them for some ungodly wasteful reasons lol)
Great Video with some very useful tips for DIY'er to do a safe and proper job. However the majority of the tools you described (and I have all of them except the MFT) are really not needed if the individual isolates the house at the consumer unit then does a like for like replacement. In this case the minimum required is a flat head screwdriver. One further tip to avoid the need to redecorate, take a stanley blade along the outside of the faceplate to break any paint attached to it and avoid it tearing when you take off the faceplate. Also rather than buy a 50 or 100m roll of cpc sleaving ask your sparky for some the next time he/she does some work for you as a couple of meters will last you a lifetime.
The sleeving is available in shorter lengths at all usual outlets in UK: Screwfix, Toolstation, TLC, CEF, B&Q. Local electrical suppliers usually happy to supply any length, especially if you buy other stuff from them. I have several diameters of earth sleeving to cater for lighting and power up to 4mm². Plus blue and brown over sleeve for lighting 2-way switch. DiY should be done by the book, even if a professional says "Don't bother"
Why do cables not have cpc/earth sleeving in place, instead of bare copper? 💁🏽♂
Nobody knows 😱
@@tonywright8294 Yes they do. It's cheaper and makes the cable slightly less bulky.
Many years ago an electrician told me that another reason for the bare copper earth was to make it easier to split/open the outer sleeve. Expose ½" of bare copper, grip it with pliers and pull perpendicular to the cable. The copper core will literally slice open the outer sleeve.
Also means you’re more likely to make contact with the cpc if you put a screw/nail through the cable…
@@AbbieMarchant
"The copper core will literally slice open the outer sleeve."
That's not why the CPC isn't insulated though. Its mainly cost.
Its not really good practice to spit the outer insulation that way, not good for the CPC. I grip both live and neutral.
Personally I use a plug in socket tester with power still on with an audible tone, you can then isolate the socket from the consumer unit by listening for the audible tone to stop, save keep going back or ask someone to listen for you, then once the facia is loosened from the back box check again with the 2 probe tester. New install measure from corner to corner as a guide to cut the length of the cable. I agree never twist the earths together, main reason if ever there's a fault on the circuits easier to default find with a multi function tester.
Brits: NO! You can't have outlets in the bathroom, it's not safe! Also brits: Smacks up the fuse box/consumer unit next to the washing mashine
The difference is that you aren't emerging from the washing machine, naked and soaking wet. Well, at least not tin the UK; we aren't that adventurous. Maybe it's different where you come from.
In any event, standard sockets have been allowed in UK bathrooms for a few years, but a minimum of 3 metres away from any wet areas (basically showers and baths). That has recently been reduced to 2.5 metres. The principle is that you don't have people who are soaking wet handling something like a hair dryer. Less of a problem with RCDs of course, but the regulations were originally produced before they existed.
Also, the placement of the CU next to the washing machine is a trifle off, but then the CU is in an earthed metal box so it's extremely unlikely that anybody using that washing machine is going to be exposed to live electrics. Washing machines also don't tend to throw water into the surroundings. If they leak, it usually ends up flooding the floor, not the walls.
In any event, that's an unusual set-up, although I doubt it's dangerous.
@@TheEulerIDwhile you may be technically allowed a socket in a bathroom now you would have to have a huge bathroom to actually be able to able to fit one!
@@dasy2k1 That bit is true. Us peasants will have to go into the bedroom to dry our hair. Not that I have much of it left these days.
british house: washing machine is in the kitchen so you take your dirty clothes to the room you prepare food in and if you drop the clean clothes when you take them out of the washer they pick up any crumbs or bits of food you didn't sweep up earlier. As a bonus you can listen to the washing machine hum away while you make your dinner. European house: washing machine is in the bathroom. A much more sensible place to put a machine that cleans dirty clothes.
@@richard-riku have you never heard of laundry baskets? In any event, my washing machine is in the utility room.
Always enjoy your videos. Any chance of doing a video where you demonstrate using a two pole voltage tester on the wiring inside a live socket? This would be to show what results the tester would come up with if the socket was correctly or incorrectly wired or if there was a problem within the circuit somewhere. The manuals never go into any detail about this.
And the consumer unit is right next to a… washing machine?!?
It's so they can wash the electrons, dirty electricity is known to cause damage to appliances.
I thought that the washing machine was always in the kitchen in the UK!
My personal tip is to put the face plate screw into the the movable threaded lug first, then when fitting the second screw, the lug is easier to find as it does not move about. Do it this way as often it is visually harder to see the lug for the second screw as the socket is held close to the wall.

“But I know you’re going to do it anyway” better to educate people in how to do it safely rather than pretend that nobody is going to try doing it.
Same reason they have “safe spaces” for people to take drugs in.

Stop these videos right now! You should not be encouraging people to do their own electrics!
Do you share the same feelings about people repairing their own cars? You make a mistake with the brakes and you can kill people.
90% of sparks won't even entertain the idea of a small job these days. Straight swaps should be safe for all but the most total of imbeciles.
Why? There are many basic jobs a reasonably educated person can do with the right tools and a little common sense. Just a little research can give you enough knowledge to replace a ceiling light or plug socket. Electricians are expensive and they usually can't be bothered with jobs like this unless it's part of a bigger, more expensive job. Mucking around with C.U.'s, rewiring, and running cables around is obviously (and legally) a job for a qualified professional but changing a socket or rose shouldn't be beyond the homeowner.
Legally you just need the work checked
Completely wired my loft extension - got a sparky in to sign off (one ring continuity fault that needed my troubleshooting skills).
Had to do some work on the 100A side at another house - again, sparky came and signed it off with one correction (I was one edition behind the spec at the time in terms of glands for the tails).
They're going to do it anyway. Better they know how to do it properly.
