UK Spur blowing RCD

[msteel9999]

I'm trying to connect a spur to an existing outlet but when I use an appliance on the spur socket the rcd trips.

I've tested the rcd and it has 19 amps capacity which is as expected.

I've also tried connecting to a different socket on the same rcd and it also trips.

What I don't understand is if I use the exact same appliance on the internal socket it doesn't blow.

I've also tried using a different external socket but the same result.

I've connected the socket with a heavy duty cable and so that the original socket has three wires in each of live, neutral and earth.

Any ideas?

Cheers

As I guess after seeing the photo with no cpc sleaving the cpc to the spur is shorting out at the original socket

It doesn't work with a different cable which has sleeving. It's nothing to do with sleeving.

I'm thinking I should hook up the wires, kill the power and test external socket for a short circuit

Get an electrician to correct the earth sleeving and test the new addition. I'm pretty sure you are out of your depth here. No shame in admitting it.

Get an electrician? I don't need a forum to phone an electrician. If you don't have a clue what the answer is don't

I think what the others and myself are trying to say is that an electrician has the test equipment needed to identify/locate the fault present here, its very difficult for anyone to even guess what the issue could be without being able to see the installation or obtain some test results which would indicate what the issue might be. They would also fit the required earth sleeving at both ends of the new cable.

From a distance we can only give the most likely causes without giving you inappropriate advice such as live testing. Obviously this is not resolving the issue and the most appropriate course of action is to seek professional advice. You need to remember you have caused the issue and by and having a dig at a knowledgeable member will not change your situation.

Mind reading or teleporting doesn't come cheap...but it's pretty obvious you don't have a clue.
It's a waste of time talking to you, pal. Play your dangerous games if you must, hopefully without involving any innocent parties.

Bit of advice - get a better electrician than the one you had before.

And put your dummy back in.
