expanding loop circuit

mikegc · 14 Aug 2013

I want to add two electrical sockets in my living room, so what I am thinking of doing is extending the loop from an existing socket, running under the floorboards to the new locations, then back to the existing socket.

I need to take one of the wires out of the existing socket, and connect that up to complete the loop using a junction box. This junction box needs to sit in the wall, but still needs to be accessible. What is the best thing to use to house the junction box with an access panel.

Maybe a metal back box with a blanking plate on top?

Is the circuit RCD protected?

Are you aware of the requirements described here: //www.diynot.com/wiki/electrics:walls ?

If there's room, crimp the new cable to one of the old inside the existing box.

If not, it might look better to have 2 single sockets next to each other, than 1 socket and 1 blank plate.

Not feasible with every style of faceplace though.

Have you thought about the testing required?

I think crimping will work, thanks.

I'll probably get my old neighbour to take a look as he is a retired election and I'd like to do the work myself.

Crimping will mean additional tools and the crimps themselves.

there is nothing to stop you making the join in the existing back box using suitably sized insulated terminals (aka choc block)

Might get a bit tight for space.

I will see what fits this weekend.
