My Son is in the process of redesigning his kitchen and one of the issues is that the electric cooker needs to be moved, approximately another 2 to 3 meters or so.
The current wiring is the old red and black 6mm running from a consumer unit situated some 60 feet away in the front room. This is a small terraced house and we didn't want the problem of ripping up all the upstairs floorboards and chasing out the plaster to replace the wiring, so we thought the easiest way was to purchase a 60amp junction box and extend the wire accordingly.
Today we ran the old wiring through the ceiling joists and then joined a new length of 6mm twin & earth to the exit point where the new cooker socket will be located. Now, what we cannot understand, is that the RCB keeps tripping and disconnecting the main ring main socket circuit.
At this point I will say that there is nothing connected to the end of the new cable, and the MCB for that circuit is in the off position, but this doesn't stop the RCB from tripping.
We initially thought the problem was with the kitchen ring main circuit, but I disconnected this completely and the RCB still tripped. Just as a matter of course, I thought I disconnect the junction box, and 'bingo' all was well. Why on earth would this cause a problem when it's not actually connected to anything and the MCB for that circuit is off? I will say at this point the cooker was working perfectly up until a few weeks ago when we stripped the kitchen out completely.
Just wondered if anyone has had similar issues and maybe have an answer?
