RCD tripping problem

[batty]

Hello Guys,All sorted now. Thanks for all the help. found 2 faults in the end. Cooker causing rcd to trip and the kitchen ring. After taking all the sockets off, unable to clear fault, but customer had a new kitchen fitted a couple of years ago and all kitchen was wired in new cable but cables leaving c/u were in older cable. Eventually after taking several kitchen cupboards apart found an original socket near the floor where the "electrician" had connected in the cable for the new sockets. Found cables falling out of this and touching between nutral and earth. Not sure why my ins test didn't find it originally but did today?? Same meter and everything. Thing was with this socket its chased into the wall originally, but instead of chasing the new cable into the wall whoever did it has just run the cable straight out of the top of the socket and screwed the face back on as far is it will go!! On top of this it is directly below a plastic push fit sewage pipe from the washing machine. Didn't have anything to sort it with on the van today so going to move it up the wall a bit and fit a surface mount box with a joint in there as it can't be used as a socket.

So you did not put cooker on Rcbo. I will always put them through Rcbo's or metal conduit. Well done for finding faults.

No I put it onto one of the rcd's, always do that and ver had a problem. Its not on the none rcd side as the cable is surface mounted from the consumer unit accross the under stairs cupboard where the c/u is, through the internal wall into the kitchen, through the back of a cupboard and int othe cooker switch which has no socket on it. So I think that should be ok - can someone please confirm.

Nothing wrong with cooker on same RCD as something else. not ideal, since a fault on one will take out other circuits, but its cost over inconvenience to why dual splits are used and not all RCBO's

One thing I would ask is this, is there a recent electrical inspection report or minor works certificate or a electrical installation certificate?

I would bet there is none to any of the above.

So I always assume that without any certificates available I am dealing with a diy installation.

I always but always issue a certificate, even if I have only changed a light fitting, its the least I can do.

It gives the customer peace of mind and a comeback if anything goes wrong.

No no cert given, by kitchen fitter. Home owner is in his late seventies and from my take on him from what I have seen in my time working there don't think it was him. He says kitchen was fitted by kitchens direct, have no proof though on any of this so its just speculation really but I wouldn't be happy if I'd paid for that kitchen to be fitted - I could have done better!

Thats one of the reasons I am joining the local trading standards safe tradesman scheme, hopefully it will be another avenue for customers to be sure they get what they need at realistic prices without being charged for work not required.
