Just bring up the wiring diagram if you are unsure del. Bring up the service manual for that product and it will help you no ends. It’s basic electrical component diagnostics - don’t over complicate things, believe in your own ability 👍
Looks to me like someone started a board change before doing any testing, did the testing when the board was out and told the customer they needed a rewire. Customer said ooooowwww much and got Ken in to finish the board change with no rewire 😂 Old Kenny boy thought oh crap what have I got myself into and accidentally on purpose bumped into his old mate Del Boy. The end. All the best del 👍🏻😅
It looks like there is an issue with whole circuit possibly. I don’t understand why you didn’t do further tests to ascertain if and what other issues there may be.
I think rewire is the best. However if the wires were traced to a point where they could be cut and they tested satisfactory then they could be enclosed in an appropriate junction box and wagos could be used. don't think it's worth it though. Thanks for watching.
TBH I hate to criticise on YT - since it's mainly entertainment for me - but there is no such thing as a 'time served electrician' who can't grasp the basics - testing and the regs have been around for too long for people to plead ignorance - Also - you basically need to be able to spell 'kitchen' (not 'kitch') when you label up. Not being a snob but if you can't, it's highly questionable whether you u/s BS 7671. Glad you're there to pick up the pieces otherwise somebody might still die.
It would be necessary to raise the floorboards, make few JBs under the floor and extend the cables. Existing back boxes must be dismantled and the walls plastered. Is this an outside wall? If so some insulation for back boxes should be applied.
Why not cut the baseboard and move the receptacles down or at least get to the slack of the cables or pigtail it where you get the access to the wire behind the baseboard? That said theres obviously moisture getting into that area pretty bad and would think that would need addressed before replacing the electrical that was compromised by that moisture..
The lady told Del that the other socket wasn't working properly also. Del couldn't have heard that fully, as that other socket should have been investigated. There should in practicality, always be spare cable behind the wall to aid pulling fresh wire for a replacement socket. However, too many sparkies and especially home handymen do not realise the advisability of spare cable.
I'd have multi tooled the skirting off just past the sockets and chased down to the floor,easy fix to put it back on and use some filler to hide the cut, to see how much slack I could find
Also, before you realised there was an issue you thought a sand and cement mix would solve the problem? They clearly have a damp issue that needs to be fixed. No ones asking you to fix it, but at least advise them to get it resolved before you set another metal back box into damp conditions
“There’s no damp in that corner” Del finds basically a swamp! 😂 And what’s that annoying bit of cable coming out of the wall alongside the BT box?? Aerial co-ax? Anyway, as soon as you pulled the first cover it was obvious this was going to be a bigger job! Another nice video - keep up the good work Del! 👍
As a French electrician I'm always amazed why British electricians don't use conduits and air-tight plastic back-boxes like we do over here. It prevents so many problems and makes repairs soooooo much easier. It's even way quicker to install.
Same in Sweden. PVC boxes connected to plastic pipes/and or flexi. Rewire a whole house can be done in a day without any destruction. Off course some house has damaged pipes, screws in it etc witch will need som fixing after but most times you can just pull out neutral, live and earth and pull new trough.
Ive never seen any residential building have any kind of emt or conduit for the electrical.. from the panels out is always just open cables that are fastened to studs every 4-6 feet with staples or some kind of strap.. per code.. conduit is only required in commercial or public buildings or outdoors or where the cabling will be exposed like in a garage maybe but still isnt required in residential.. ive ran houses with liquitite conduit but those were one off builds that the homeowner drew up the plans and had it all approved n all.. otherwise nobody would pay to have that done mostly because people are dumb and wont ever know the difference or care either way.. hell you can use a type of insulation that will fireproof inbetween rooms for just a few dollars extra a foot but theyd rather go cheap and get it done..
That green color is most likely coper oxide. That means that the wire has been attacked by corrosion and that the water is washing away some of the coper oxide. She says that she's never had any damp issues in that corner, but I don't beleive that for a second. The evidence that you've dug up is quite damning.
You get yourself into some situations delroy. It’s nice see you been helpful and respectful too your customers hopefully damp has stopped as that my concern how sockets have gotten so much corrosion is main problem. Hopefully this lady gets everything sorted lucky there was no serious damage with burning.
I find with metal back boxes, if you're using bonding plaster, just knocking the round grommet holes in around 2-3mm gives more than enough fixing when plastered in - certainly stronger than rawl plugs and screws although no harm in using both. Sets like rock! Agree whole heartedly on using conduit or similar container to run cables under plaster. Some say plaster eventually eats into the insulation. Not sure about that but pros always use conduit as it makes the circuit fully serviceable/replaceable in the future. Yep, takes more time but its a proper job then.
Bonding plaster does hold the boxes really well I try to use screws as well. Agree with using conduit however, it shown in text books twin and earth cable in the with no conduit or capping. Thanks for watching.
I had the same issuie on one Job as replacing it with another metal boxes will corrode again if the property has damp issuies...So I fitted plastic conduit twin back boxes instead of replacing it with a metal box..Same wavelength we are on..As Yoda would Say ..Lol
Would the breaker have to be downrated so it can be run as 2 radials especially as its lost earth ? Or will the 2 radials be ok with a path bk to cu via an earth ?
The green goo is caused by the plasticiser reacting with the copper. The real danger is the gerrn goo can effectively cause a electrical fire. The area should be recommended to be rewired asap. Personally i would have told her that the skirting board needed to come off its only a couple of foot long.
