Went to have a brief look at a job on Saturday.
Gentlemen had a new consumer unit fitted about 5 years ago.
The installer that did this found a fault on a circuit consisting of 2 sockets. I've checked this and there is a fault between Line and earth somewhere.
Not a bad job to do as the CU is under the stairs (center of house) and the sockets (1 in Lounge 1 in Dining room) are feed through the walls of the under stairs cupboard, with the sockets on the other side of the walls - absolute breeze of a job really.
The odd thing is that, it's a 32A MCB protecting the circuit out of this comes about a foot of 4mm this is terminated into a JB and then a 2.5mm 'ring' supply the 2 sockets has been wired from this JB.
Maybe I've lived a sheltered working life but I've never come across this before. The owner says the sockets aren't original and there are several other things int he whole set-up that suggest this too.
What I can't understand is why someone would wire it like this, if they have come from the board in 4mm why not just carry on with it and have 4mm radial on 32a MCB thw whole run is only around 5 meters - was this a way of doing it way back when?
