Hi all

I need to move a couple of sockets by about 6 inches but there's no spare
cable to play with.

Is there an approved method for extending cables if the 'extension' is to
be plastered over.

Cheers

Jim

Yes.

You need to have some crimp connectors and a decent crimping tool.

May I just add for the OP: "Decent" means a proper ratchet crimper with
compatible crimps.
