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.
Cut the outer jacket from the end of each cable to a length of about
40-50mm, then cut the conductors, staggering them. The idea is not to
have the crimp connectors all in one position. Put green/yellow
sleeving on the bare conductor of each and then crimp each conductor
into a barrel connector of the correct size.

Finally take some heatshrink sleeving, ideally with hot melt glue
already inside and then shrink it onto the cable assembly with a heat
gun.

This meets the electrical and mechanical requirements.
