That BS951 clamp on the supply cable is worth mentioning to the DNO. Watch out though because the last time I rang Western Power to notify them of a similar arrangement, they stated that the earthing arrangement was now a TT (for a suburban house in Birmingham!), so they no longer had to maintain it. The customer had to pay to get the supply 'converted' to TN-S i.e. to remove the clamp and do a proper connection onto the lead sheath. Next time I'll start by asking for a formal declaration of Ze or earthing arrangement for the address, and then hopefully they'll have to stand by that when I mention their dodgy BS951 clamp.
I've started subscribing to this channel. You look like a good experienced tester. 2391 was a Written no book exam when I took it and I feel looking/hearing your explanation you took yours when it meant a bit more as you had to work harder to obtain it. These will help people learn the ropes as even getting the qualification still means learning daily at times.
Really good video, you showed us a EICR with quality explanation and you got good footage even with the customer present. Good follow up at the end and the length of the video was great. A lot of sparky videos “no names mentioned” are rambling on a bit and tool reviewing tools that have been reviewed and reviewed and reviewed! Great content, great sparky 👍🏻
The property definitely needs dragging into the 21st century. As well as the remedial works, I think the landlord should give the ok for extra sockets to be installed. You could mention the lack of socket-outlets in the 'comments on the existing installation' box 👍
Great video, Poor installations I work out the cost of a rewire & a cost to put the installation right & give both to the client. I always tell them to get other quotes, so they know I’m not out for work. If the installation requires lots of remedials, fault finding, I always inform the client that it’s also a gamble of going the repair route as parts may require rewiring & therefore could end up being an uneconomical repair. Also once you delve into the install further you never know what your going to find. Extension leads on that scale warrant a C2 without a doubt, tripping & fire hazard. I never check R1+R2 on a ring during a domestic periodic, for the following reasons. It is an existing circuit & not required. Resistance from old sockets gives you false readings I always check for ring continuity at every socket sampled, this checks for Spurs off spurs. During my initial inspection, I use my R2 wander lead to every socket screw, confirming the cpc is in the correct position. The Zs test will confirm the polarity of line & neutral conductors. Just my way of doing it. For the apprentice, You can also measure ring continuity at a socket outlet, rather than an overcrowded consumer unit. I like to think sparks help each other.
Good run-through and explanation Patrick. As usual when dragging an old installation into the 21st century and indeed up to today's standards something's are self-explanatory. Some landlords take and respect any advice I give them and some run their whole property portfolio at an absolute minimum! After chatting with the tenant on the day I believe the low resistance reading is in the kitchen. I won't go into it too much on here but I will plan and prepare for a couple of different scenarios to put the place right. Sadly as with some cases I might not hear from them again? Thanks for your comment.
R1 + R2 is a good test as checks polarity and which sockets are spurs (the installation may have never been tested since fitted to confirm polarity) . Very quick test once L + E connected. Some sockets may need the test plug inserted 3 times to clean the contacts.Taking a wander lead around all sockets will take longer. You are testing the installation and anything plugged in to the sockets cannot be classed as a C2 as not part of the test. You can advise the person ordering the EICR they need more sockets. I can't find anything in Codebreakers either.
I agree, the amount of equipment and appliances we use today compared to 40 years ago has been lost on this installation. The poor guy had so many extension leads everywhere.
What a state that 3 way spot light was in, makes you wonder what they were doing, to have all those smashed lamp bases in that! Seeing the 1980s style MK logic double sockets, they were some of the best ones that MK made, (better build quality than the modern ones!) providing they are not damaged, last almost forever, I've still got them in my place never had any problems with them. Regarding extension leads, providing they are in good condition, not really a problem with just low power consumption items plugged in, you could have a 6 or 8 way extension with a load of phone chargers, or AV equipment & it would only be less than about 100 watts. It when the clueless people plug in a couple of heaters & hairdryer that the problems start!
Those screwin bulbs are always breaking off in old light fittings-have you ever seen a bayonet bulb break like that? Probly never. So it makes me wonder why almost all light fittings take E27 bulbs(except integrated led obv.)
Recently found you good videos my man, you should do a van tour or a tool tour! The tool tour is just so I can see what purchases I could make lol! And the van tour is just to get ideas on how to keep a neat van! Keep up the work dude!
If I had to turn up to that property I may suggest a full rewire. Two circuits within the c/u and old wiring with no RCD protection as you say. That would rectify the isues faced, but does it then become an ethical issue? As the Electrician who has tested it, it may look as though you are out to get work from testing letted properties. It's a difficult situation, you can educate people about safely using extension leads but when it causes a fire it then presents a whole load of other issues. Great Videos, really interesting to here your thoughts, knowledge and what you get upto!
Nice video, only bugbear was that the insulation resistance test should have been carried out with the cpc's connected to the MET, other than that great video 👍
@@harrypotter101000 It states in BS 7671 that this is how IR testing between live conducors and earth should be carried out. There may not be a short circuit between live conductors and cpc but there may be one between live conductors and an exposed conductive part.
Never understood why people think extension leads plugged into extension leads are a problem. So long as the correct size fuses are fitted how can it possibly cause a problem?
Theoretically multiple extension cables can't be overloaded because they are protected by 13A fuses, but BS7671 says that there should be enough sockets to avoid the tripping hazard of long and numerous extension leads. As far as the 13A fuses go, it seems to me that the typical 13A plug is not capable of handling that current for a long period unless all contacts are clean, fuse holders tight and conductors screwed tightly into the brass pins. John Ward has done a video recently showing how 13A fuses will not even disconnect until the current gets past the region of 25A. I reckon we should reduce fuse ratings to 10A maximum to take the limitations of the BS1363 plug into account.
westinthewest I think you’re stretching the term numerous to apply it to two, you’d possibly have an argument at say 5. The other point is a case of bad housekeeping leading to a tripping hazard, that’s not a failing of cable reels/multi bars. I recently made the mistake of plugging a heat gun into a multi gang and it blew the fuse, it was supplied with a 5a fuse. I’ve checked quite a few since and it seems to be the norm.
I think the problem is the majority of the general public don't understand how "daisy-chaining" multiple extension leads lowers the resistance considerably (resistors in parallel), hence why the cabling soon gets hotter etc. More should be made of this in school physics lessons.
@@richardwilliamson3624 It's a very expensive way of getting power to your sockets... When I worked on industrial sites, we wired rings in 4 mm but only because of the size of the area to be covered and volt drop issues.
@@richardwilliamson3624 I disagree... the cost of a drum of 4 mm t&e compared to a drum of 2.5 mm t&e can be as much as double. To remain competitive in this business, you've got to keep your material cost as low as possible without compromising on quality or suitability.
I picked it up from Screwfix about 18 months ago. It's great 3 hours on and about 4 hours to fully charge. Here's a link.. www.screwfix.com/p/luceco-led-usb-rechargeable-site-light-10w-5v/5276k
What could be causing the 0.11ohms insulation resistance reading? Is there a way to isolate the boiler? Looks like the double adaptor plug is unfused with uninsulated pins.
I isolated the boiler in the kitchen, that flex coming from it plugs in in the kitchen. As in most cases a low reading like that on an EICR requires further investigation.
It may look untidy and unprofessional and look a bloody mess but provided the extension cords are properly fused at 10/5/3 amps and nothing high powered it plugged in (fan heater, kettle etc) I fail to see how this is a fire hazard. Problem is 99% of people have the wrong fusing in appliances and extension cords and absolutely no idea of how electricity works, far less an understanding of current. I suppose that if you factor in the times when extension cords have wiring exposed or the wrong grade of cable then it could be a problem. As someone who worked with test gear and has done all my electrical house wiring forever I would postulate that extension cords are not intrinsically unsafe. It's just the people that use them that are the problem.
although its not ideal, but you could have 10 or more sockets on an extension lead, and as long as the cable is capable of carrying 13amps and theres a 13 amp fuse protecting the lead wheres the danger, it will just blow the 13 amp fuse in the plug top, if over loaded with no damage to the cable. Also the kitchen light is just as dangerous as your average pendant, without a lamp in anyone has access to live parts, cant believe we are still fitting those things and passing them as safe, in this day and age. As well as electric showers, like having a bloody kettle on the wall, theres no way i would recommend an electric shower or have one in my house.
