Hi ALL
Just thought id put this one up for all those faults we find.

There you go now for yours !

New twin RCD board install, replacing wylex rewireable one.
Energised the board.. trip.
Id tested the whole house prior to the job with not too many faults...
However, it'd had lots of work done to it over the last 20 years.
The main culprit was one of the RFCs. However, there were other circuits which seemed to add to the problem.
Took the RFC in question, split into 2 radials to narrow the fault. Identified the half causing the problem and split that down even more.
Eventually found this in a socket, spurred off the ring. The little nick in the wire was just touching the earth terminal of the socket. Snipped it out and re terminated.. hey presto everything fine..
The annoying thing is it didnt show out on IR test, even when testing just that spur from the other side.
The only explanation I can give is that it must have been a fraction away from the contact, but when energised it was close enough to jump the gap..!!
3 hours of hunting... but got there in the end.
 
Today’s little adventure!

If you have ever wondered how many wires you can squeeze down a 20mm coupling and into a surface mounted double socket box then wonder no more. It’s 12x 2.5mm singles and 1x 2.5mm twin and earth cable. If I had not seen it for myself I wouldn’t have believed it.

Needless to say it’s no longer like that now!
 
Got a pic Kam? sounds like a right squeeze!

Someone took a ring of the ring to another nearby socket and then for good measure added a feed for an extractor fan as well. Unfortunately forgot to take a picture but it took me ages to strip it out. The T&E had a twist in it as it came through the bush. But that is the most 2.5’s I have seen down a 20mm hole. Once saw 23x 1.5mm singles down a 25mm galv. conduit with two 90* bends. But that was a long time ago and it’s still there and working.
 
Customer asked me to look at why a downlight wasn't working. Removed it to change transformer and was astounded to find a 13a plug-in transformer pack into a socket (with no backbox) terminated on the end of the lighting circuit in the ceiling!

Amazed.

called to a job where socket in kitchen was not working, i asked client if he has juction box underneath and he said no, i told him there must be junction box under there, anyway long story short, found a junction box with wire bitten by a rat or mouse who probably died, rotted and decomposed.

so the socket stopped working when a rat bit the cable did it?
