RCD tripping

[Gixxerdan]

I have just installed 3 new sockets in my house. Before putting power on I went round with my multimeter and checked the resistances between earth and neutral/live to check there was no shorts and all tested ok so went round with a 240v rated floodlight to check all of the sockets with the power on. Plugged in to the first double-worked but then plugged it in to the other side of the same double socket- rcd tripped! Now it trips everytime I try plug something in. Any ideas? Ive tried a couple of different equipment and have gone round checking for loose wires but now im stuck... help please!

Could be damaged insulation when putting the socket up to the backbox opens up and goes to earth, but that's only a guess.

Where are you? And don't say your living room...

Re-establish the old ring (with a spare piece of cable if need-be) thus disconnecting your new sockets, then check if rcd trips when old ring is established how it used to be, if this works then IR test your own work and take it from their, has the plasterer or paint got into the back of sockets etc it could be tracking under load.

Forgot to add, did you trim back the outer (grey) insulation with a stanley knife?

Yes i did. I checked at the time of doing it that I hadnt nicked a core but i will double check in the morning. Thanks for the advice guys, I will let you all know if I get anywhere in the morning. I dont have an IR or ELI tester so checking the cables for nicks is the best I can do really.

There's a few methods for stripping T&E, some are on this video but I'm not a fan of the knife method.

Note the lengthy speech on the merits of stretching the CPC and the perfectly manicured nails... :lol:

Well i like your method for live testing, sheds a little more light on the situation, most of the time!

And you get a free suntan lol

Found out what the problem was... I didnt realise that the neutral was split in to non-rcd and rcd sides... i just connected in to a spare neutral. Connected both ends of the ring main into the same connections and it now works XD

At least the problem has been solved.

And how he pronounces TH as F or V.
Sorry but that annoys me
