What the most shocking thing that you've found on an EICR...
'so that they're all at the same potential difference.' ? Surely you mean 'so that they're all at the same potential.'?
60A main DNO fuse blown, replaced with wire between the blades and MANY other bodges over the years!
I love how i watch this but half the video i sit here thinking "what the fuck is this dude on about?"
First question refer to public comments
Can you do a video of how many electricians abuse the now regulatory 5 yearly EICR for landlords. In my experience you request an electrician does the inspection he doesn't sign off and gives a bill of thousands of pounds for minor issues. E. G. I had a hairline crack in the consumer unit and got a bill for 800 to come back and replace it.
Really like John, talks a lot of sense and knows his stuff. More John please 🙏
Lots more coming up!
Loved the tips from his DNO perspective 👍
agreed more of John please
Maybe he can, once and for all, provide the DNO answer to the question, whether the DNO would notice a pulled cut-out fuse, if a smart-meter is fitted 😄
(That question came up in one of the earlier videos)
@@artisanelectrics he is very knowledge and knows his stuff 👌🏻
John seems to really know his stuff, a great asset to the team and Jordan still learning is the reason I love this industry. Always be ready to learn more.
I'm completely new to electrics,16 and I've fallen in love with electrics!
Literally changed my entire career path as I find electrics more enjoyable than any construction skill.
You're a great help for me as I'm learning quite a lot.
Thanks so much for your work!!!
The look of confusion as he heard "Is it half a day"
Johns info about the MCB date, Love that kind of knowledge. !
Really good video. Getting a more in depth look at some of the more regular things you do day to day. Really good to show that regardless of how experienced or knowledgeable you may be, there's always something new new to learn.
Every company needs a John, conscientious and knows his stuff. Great video from you both and looking forward to the next instalment.
A great film, it answered a lot of questions for me.
Jordan and John have some fantastic electrical knowledge.
Well done, I would love to see the board change in part two. 👍👍👍
I really liked your explanation of C1/C2/C3 codes in this video Jordan. Those skeleton boards are also quite common in London apparently.
Brilliant video again, thank you. love the technical explanation yet you always bring it back to simple terms and great explanations. Love your work.
More please - Looking forward to seeing Part 2 - Consumer Unit install. John has taken being on camera like duck to water. You can tell he's got a vast about of knowledge. What a great asset to you business Jordan.
Couldn't agree more! John is brilliant!
Really enjoyed that fella’s,John looks like a great addition to the ARTISAN TEAM.
👌🏼
You really take pride in your work. Very informative video. By the way, the PSU at 08:55 is supposed to be used within an enclosure or device chassis. It is not rated to be left exposed like that.
Scary what you can find when you scratch the surface. Definitely would like to see the board change and solar battery install. Another good vid artisan team!
Just a quick tip remove the consumer unit cabinet surround makes it so much easier to see the incoming cables and gives you a lot more room to manoeuvre.
Guys - great video. Love all the details and explanations of the terms. As an American it helped me to better understand your processes and regulations. Would love to hear more from John.
Absolutely class act and generous with explanation, especially with the technical terms.
Watching this from Singapore, and we do match British electrical standards fairly closely.
Please keep up the quality content!
Good to see Jordan on the tools again, John’s obvious experience shows. Well done
Interesting video and would definitely want to see the board change, and the solar install.
👍🏻
“The names Arthur, Arthur Day!”
But seriously I love that Jordan helped John out rather than him working on his own! What a boss 🤜🏽🤛🏼
26:20 Standard square shower pull cord switch issue.
I use the round Crabtree ones, you fix it down and then terminate the cables with nice bend radius.
Neon is connected to the cover so ideal for I.R. testing, just fit it after.
Crabtree are far easier to terminate, especially if they are 10mm
One of the best video on the channel... So much Informative and well prepared
Many thanks, glad you enjoyed!
What a helpful video this is, studying for my 2365 at the moment and this has so many intriguing insights, thank you
Regarding the 1mm feeding the spur, I was taught not to use different size conductors in the same terminal, if you're going to install a spur for a small load use 2.5mm then reduce on the load side of the spur.
A mate of mine was carrying out PAT tests and found an extension lead made out of coaxial aerial cable. It was coiled under a rug so that the renter could keep his feet warm.
😳
Reminds me of an old elderly cple that saved on heating by placing coins behind the old Edison fuses scary lol
Great Jordan enjoyed your videos learn a lots while at work have spare time keep watching and learn thanks and appreciate for time take care bro
I would love too see more on this installation and upgrade. thanks Artisan Electrics.
12:09 - a tricky one: not sure if it applies, but IEC 60364-4-43 433.2.2 says something like "the protective device can be along the run if there's no sockets, no branch circuits, and it's protected against fire and danger to persons"
Also, at 13:13 - sure 2.5mm² isn't great here, naughty at least, but if the upstream protection was like 16A, what class fault would that be? Nuisance trips if you ever actually plug something needing 32A in, sure...
Do you have a video explaining ring and radial circuits for us Americans watching? Im glad you explained all about the EICR's, sounds like the UK's regs are far more stringent that here in the US.
John is great, his knowledge is incredible. He brings a more informative, and educational style to the videos. Over the more humorous, and less serious vibe that Corey brings. Also, the way Jordan says "marijuana" at 15:44, just brilliant.
Glad to see everyone is enjoying the content from John!
Marry-wana 😂
I'm on a looped supply from a 1950s ex council house. The DNO put an 80amp fuse in my side, and said next door wouldn't be able to go above 60 now without unlooping the supply
those class 2 metal light fittings with the plastic box are designed for singles peing run through conduit. Where I've fitted them, I have used a bit if PVC sleaving from the exit of the conduit to the plastic box for the line and neutral and have crimped a ring fitting to the earth wire and attached it wall/ceiling mounting
The 1 mil off the socket is protected against overload by the fuse in the FCU, no matter what. The one potential issue is short-circuit protection if the cable between the socket and FCU gets damaged. If the socket is on a 20 amp or smaller radial the MCB is probably sufficient to protect the cable, if it's 30 or 32 most likely not. RIngs and 4 mm2 radials are precisely the reason why BS1363 plugs have fuses in them (and of course overload protection of power strips).
4 MΩ is theoretically a pass but anything less than high double digits would leave me a bit concerned there might be something on its way out. With plenty of loads connected it's probably just a bunch of Y capacitors affecting the numbers though.
Great video of all the defects thY wr come across on a day to day basis.
Hey hey, it’s not “obsessive” to want to monitor your power consumption. I have the same Emporia Vue on my breaker panel (what you call a consumer unit). It works great.
Hi, great video. Just a comment, not all DIY electrical work is dodgy! I agree that people shouldn't do any electrical work if they don't know what they are doing. I have just completed a full rewire of my 3 bed bungalow, it was extended from 2 to 3 bedrooms. I needed to get an EICR so I could apply for my completion certificate. I got a pass (satisfactory) with no faults found. I went for all radial circuits with an RCBO board. Many thanks to you guys, David Savery and John Ward for your fonts of knowledge!
Exactly. I've had to fix work by every professional I've ever used
Love watching your guys videos! Really makes me realise how rubbish my electrics are in my house! 😕 plus working on building sites you guys give me that bit more Knowledge of what the electricians are doing 😀
Well done gentlemen. I will definitely watch the board change and the battery install videos.
The face on Jordan - looks like he was caught with his pants down 😁
Another great episode guys and very informative 👍
I was told by an electrical tutor that it was OK to use 1.5mm twin and earth on a 13 amp socket ,double or single provided that it was supplied by a connection unit with a 13 amp fuse. 1mm maybe OK in some circumstances but if any correction factors had to be applied it may end up with the cable only being able to take say 11amps and the fuse rating at 13 amps so I don't think it would be a good choice of cable with that fuse ,although with the short run of cable you have there I can't see there being an issue,although strictly speaking I don't think it does comply with regulations.
Interesting video,thanks for uploading .Happy new year.
Thank you for sharing. Very interesting!!!!. Could i ask about the battery storage, is the loft the best place for placing them. Just thinking of weight and temperature fluctuations. Also fire risk. Keep up the good work.
I was thinking the same... however its actually what is stopping me from doing my batt install in the loft.. everything is wooden so not chancing it. I'm now leaning towards doing it in the garage but it means I got to run a really long cable.. kitchen is the next best and easiest area for me
Nice to see your keeping your quality in tradesmen , with John being a excellent addition ….
10.5kw shower.... Hold on while I go back to that fuse board in the video. Doubt it's on 16mm either. Doubt it's on 10mm. 6mm? Maybe. 4mm? Possibly....
Edit; kept watching, that blackened wiring is not surprising!
Worst I’ve seen was steel conduit covered in years of paint feeding an outdoor front porch light that had been connected to line rather than cpc, tenant reported occasional ‘static shocks’ when switching the switch. EICR for landlord on domestic premises.
The 0.05 ohms is like a max reading for 10mm earth cable as it’s it’s good for about 27-28 metres. Hence if it was not in range, you may have to up the size of cable but in domestic you wouldn’t as it’s never gonna be that more than a 28 metre run, so we would probably just replace it for another 10mm earth cable. GHS Electrical done a video a few years back on it saying something similar. Keep up the good work.
Great save from Jordan, jumping off the gas bonding was on the tip of his tongue there 😜
19:52 what a plesent suprise i have the same technics su-v500m2 amp
re the outdated MCB and RCD, use an old copy of the regs to check they still pass the tests. Then decide whether it's immediately dangerous, needs replacing, advisory or nothing. If they trip at the right current/fault, old or not, they aren't unsafe. That's not to comment on whether there are other reasons for an upgrade.
Please have a video with John telling us everything he knows! What a great addition to your team!
Another fascinating video! And yes, board change in that property would be an interesting video too.
Noted 📝
Being from the US, seeing 40A and 60A services is crazy to me. The average house here has a 150 or 200A service, 120/240 split phase. 400A is common on all new construction. Some areas have residential 3 phase, usually 120/240 delta or open delta, but sometimes 120/208Y on a main road. My own house has 100A 120/240 open delta. 100A is almost never installed in new construction, and really was only common 1980s and earlier. Power company where I live is phasing out open delta services, so to upgrade to 200A, we need to wait for the power company to connect us to a 120/208Y transformer set that's on the next pole over. Waiting to hear back on what the max amps we can upgrade to is. Usually 200 but they may let us go 250-300. A 60 amp single phase service here would have been installed in the 1950s or earlier. Unfortunately most power companies in the US will not allow 3 phase for a residential customer so people are stuck with these ridiculous 400 amp single phase services. Lucky to live in one of the few places here where it is possible.
Good video as always. We have just had a hypervolt fitted can’t seem to get WiFi to it where it is placed, what booster would u recommend with it being 20 metres from the house.
Spurs off rings:
1.5mm2 for PVC insulated copper cables or
1.0mm2 for MICC copper conductor cable
The water pipes in my Swindon home is a rubber reinforced pipe in a tube and are not therefore bonded to the pipes at that point. But the pipes etc are all buried into a concrete floor. The Electrics are unusual in that all the sockets are on one ring coming from the first floor.
That's a sweet tomato grow setup there. Love all your videos, keep them coming!
Great informative video as always. BUT...Was John working on a live light installation at the end there?
BS 3871 was assimilated into IEC 898 because the responses were close enough to each other to make 3871 satisfy the same standard, which is why it was part of tables right up to now. BS 4293 was not assimilated into 61008 because they didn't satisfy other parts of the standard, hence why the 4293 standard is not recognized by 7671 (does not appear in the reference tables) and hasn't been since at least 16th if not before. The trouble is, 4283's respond faster than 61008 (200ms vs 300ms) and are pretty rock solid until they fail, but they are prone to failure.
I haven't bought Amd 2 yet so I don't know that 3871 has been removed, but it is surprising to hear since nothing about them has changed...
Really don't like those shower isolators with one screw, you can't be confident it's not gonna burn up again esp on 10+ kw
You know someone really bodged up an outlet install when an electrician just takes one look at it and re-terminates it, just to know it's safe.
Yes to the video of you changing the CU - great videos! Thanks
My personal opinion on the cooker hood is that if the wire is thin enough then your going to have a higher resistance and if it shorts you won’t necessarily get enough current to go through and trip the protective device in the time period you want. You could calculate that. Couple this to the lack of rcd and it’s starting to smell risky. You are not going to pull more than the in line fuse will pop at so wouldn’t be concerned about the motor failing and pulling more current as the fuse will blow.
Just the possibility of a fault between the fuse and the socket which has the fuse for that supply ie 32amp or less. You could code it as a c2 but it’s unlikely to fail so c3 and let home owner know.
Hi Jordan great content as always. yes I would love to see a part 2
I’m no electrician but enjoy watching how it’s done professionally 👍🏻 I used to watch Tom on UA-cam but he seems to have disappeared 🤔
John is a great addition to the team, great hire guys
Glad you think so!
The overall resistance doing the global IR, is always lowest than the lowest one. So recording that value is fine as you know all the circuits are within the required limit of 1 M ohm
1MΩ complies but only after further investigation to ensure no latent fault exists.
GN3: "...where an i.r. of less than 2MΩ is recorded... each cct should be tested separately."
Basically, if there's VIR or MICC (Pyro) in the house you really need to know if it is degrading by taking proper readings and comparing them with (snigger🤭) the previous test results.
Definitely 100% need to see the follow up!
Brilliant Vid Gents, most informative. Keep up the Good work, there's a lot of people watching you who Don't Understand the work load going into a Simple situation. That's why they need Professional Help! My Local Solicitor chargers £600 PH in 10 Minute interval's.... And We're Considered to be Expensive by people whom cant Understand the Bigger Picture in Electrics... Yet they understand a Solicitor Word for Word... and freely Pay them a Fortune. Planning is Key People!
as an American the whole concept of required inspections on electrical work is interesting. just today I pulled an 8 AWG which is a 6.0mm cable right out of its screw clamp on a brand new RV. the amount of wrong and intentionally bad wiring I found is just amazing. how a manufacturer can put a 55A output power converter on an 8 AWG (6.0mm) cable and then put an auto-resetting 40A breaker inline to "comply" with the wire current limits. but that breaker will be thermal cycling for the rest of its short life and fail prematurely.
And then the RV company will charge him over the odds to replace it for what shouldn't have been installed in the first place, because lets face it, a lot of people go back to where they get the vehicle from instead of finding someone who knows what they are doing.
That moment in Jordans life, when he opened a board and he and his one single ct clamp for the zappi were soo lost in that ocean of ct clamps 😂
During the IR test it appeared John tested individual circuits at 500V without worrying about any devices still connected. This is about 22 minutes in after the global tests, he states he is testing line to earth without the neutral. I can see the meter is on 500V. I'm new to this but I am always ultra careful before testing at 500V. I didn't understand his comment along the lines of the Megger will always bring the voltage down. Did I miss something or can anyone explain why he was not concerned about the risks of 500V between line and earth and his comment about Meggers?
As a former ADT Sparky Its uncommon to install a switched spur. Its usually Un Switched for a Intruder panel.
I did a separate line for each room and category. That is overkill but it is safe. So it is like 3 lines just for a my working room - 1 for lights, 1 for outlets, 1 for a AC. My switchboard looks like a nuclear power plant control center. It is expensive.
Like the wander lead reel. I bought some of these myself for work which makes life so much easier.
Presumably you would contact the DNO about the looped supply before installing the EV charger?
I know Western Power will upgrade the supply free if its looped and you're installing EV, however I'm not sure if all DNOs must or if its discretionary.
Currently, DNO's have to replace the feeds FOC due to the green agenda from the govt. However, how long this will last is anyones guess, but currently, FOC
I see the short wires in switches and sockets all the time in houses wired pre 2000. Really can’t believe that you didn’t know about the phase colour dots. 😂😂
I’m sure you get this a lot, but as an apprentice who would like to gain more knowledge with testing and eicrs these videos are great 👍
There is a chance that a rewire is in this house future it may be easier than just a simple breaker box replacement.
Jeez -- that place is a fire hazard waiting to happen 😱 An insult to Chimpanzees ... they're highly intelligent and physically _very_ strong, and they could be trained to do far better than this.
I would love to see a follow-up to this 👍
Guess he had to be really careful with the customer being around (customer has past electrical experience :)
John is a standout (head and shoulders) sparky. You are building a great AE team.
The MCB's would be a C3. It's just doesn't comply with the regs. It's not immediately dangerous.
The kitchen extractor I would code a C2. The only reason I would is if something happens in the cable going to the spur. It would exceed its current rating before the breaker trips. Otherwise, it's not an immediate danger.
Out of curiosity, what are your opinions on class 2 double insulated metal (brass) light fittings?
Don’t Schneider Electric do something for monitoring circuits in their boards from what I remember? Possibly maybe just their commercial / industrial range launched in the last year or so but from memory the monitoring modules connect via WiFi.
i once saw my boss working to fix machinery on a 3 phase supply he opened up the panel to adjust the plc he slipped with his screw driver and i went blind for a second as the rail pretty much exploded. he soon replaced the entire panel
What a brilliant video! Would love to see a follow up.
Sure thing 👍🏻
John is a great addition to the team Jordan. Artisan obviously attracts the best. Chris.
Un-looping isn't expensive as it's the DNO's responsibility. I installed a meter box and armoured 3 phase cable to the new consumer unit and they did the rest. Now have 3 nice 100A phases of goodness!
RCD's. Very important piece of safety kit.
I moved into a newbuild some years ago. After a couple of weeks, an RCD would pop after switching on the kitchen light. Got a local sparky in to have a look and, after about 15-min's, he told me he had cured it. I asked him what he had done. He showed me how he had swapped the RCD for a switch. No more problems! 😱😱😱
I gave him a verbal boot up the arse and got another sparky. Turned out that when the kitchen light had been installed they had drilled through the cable and there was an intermittent short between live and earth.
If it keeps popping, there's a problem!
Should it knot be C2 due to OCPD being greater than the current carrying capacity of the cable I know its a fixed appliance that can't pull probably more than 5amp and it's a bit of a grey area but cable reduced prior to spur not good
Marry-juana grow 🍃😂 Excellent video guys, super informative 💡🙌🏼
Good work guys, John is a rod bloke, could you ask him where he gets his glasses, as I could really do with some that double as safety glasses.
You always choose the fuse for the load then you have and choose the cable after that so the cable and the things attached to it is always properly connected but I don't know how you do it there(Germany)
I would surely feel very comfortable using your services for electrical installations and inspections.
hey bud l am not a sparky but l do have a basic understanding of electrics (l basically play around with 3 volts up to 12 volts ) and some of the thing you show in vids is very interesting
More John plz.. Seems a good likeable chap... Knows his onions too
I can just imagine the builders I've worked for, " how much? " " how long?" " hurry up then!"
The quality of the painting job in that place reflects the electric work! 😆
All RCD breakers are supposed to be failed if they are put in the fuse panel before 2018. This is due to the amount of DC circuits in the circuit. You need a DC rated RCD for circuit with DC circuits connected to it. (DC circuit I mean devices like LED lights, electric car chargers, washing machines and other stuff that might have DC PSU in them)
The responisble thing is to change the MCB's also to the same brand as the RCD.
This is how we are suppose to do it in Iceland, you guys in the UK usually have harsher rules.
Older devices...just because they're not in the regs now doesn't make them a fail.
You've got to remember that you're testing an older installation and may need to refer to older material to do so correctly.
The harmonised colours are a good indicator of vintage of alterations, makes it easier to determine if someone hasn't applied the protection updates (typically RCDs) that they should have at the time.
I've had unaltered 1970s installations with Wylex socket outlets and 3036s.
You can advise the absence of RCDs but if nobody has altered anything and it tests correctly, it passes.
If you found it had an extra socket added in new colours, someone didn't do their job properly to the standards of the time and it becomes a fail, even though the level of protection is no different.
That RCB is an issue. Don't know what the regulations says about it, but those older ones really don't like (as in failing quietly) DC feedback from things like inverters, chargers, LED-drivers and whatnot you now find in every typical household.
Wonderful stuff. Batteries in the roof ? How do you deal with fire risk? No emergency service is going to risk it.
16:48 Given how concerned these guys are about safety, I find it funny that they're ok with electric showers... and this one didn't even have RCD protection 🤣
