ERm could you actually have a faulty bit of cable. It will be interesting to
see what happens as you screw them all in starting from the one you had
issues with.

I've been updating the kitchen ring and came to a point
where it was ready for testing.
Most of the sockets are ok (3 lights on the socket testing device)
I put the testing device in the left hand socket of the last one and
this gave the ok (3 lights)
When I pushed the testing device in the right hand socket it went
bang
before even switching it on.
But after resetting the consumer unit the other sockets where still
good and left hand side socket was still good.

Any ideas, gents?

Thanks.


My
guess would be that the socket tester is a red herring and any
plug inserted into the RH socket, or even pressure applied to the
RHS of the plate shorted your wiring perhaps to the metal
back-box.
If it went bang as you said, aren't their any sooty deposits to
show where the failure was?

But there is no discolouration and with the mcb rset the good side of the
socket still gives 3 lights.
Thats the odd thing! It went bang twice, the 2nd time a tad more of it.



Important Update!!! All of the socket plates are not yet screwed down
and I've just retested it after twisting it a bit further away and now
both sockets show 3 lights from the tester.
