Adding a double socket

[R Stringer]

Hi all,

I live in a 2022 new build and I’m planning on adding a double socket from spurring an existing double socket on the ring main in the adjacent room using 2.5mm T&E. The wall is a partition stud wall which is insulated. The new socket will be installed higher up the wall in the adjacent room to power a wall mounted TV.

I have checked the double socket I am planning to spur off and there are two cables, one in and one out. The circuit is RCD protected with a B32 breaker.

To my understanding if one spur is coming off the ring, then a 13A FCU is not required. However, I had other additional sockets added during the build in other rooms to power wall mounted TVs (this one was an oversight) and the electrician has spurred to an FCU and then into the double socket.

I’m just wondering what I’ve missed as from what I could see, an FCU wouldn’t be necessary?

Is it necessary to run the T&E in conduit in an insulated stud wall? Or not as it is RCD protected?

Many thanks

One double socket on a spur doesn't need to be fused . If more than one on a spur cable then a fused connection unit can be installed and the sockets connected to its load terminals ,thus protected by the fuse.
Conduit isn't required.

Or use 4mm then you can add more than one socket.

Two cable to a socket, might not mean that socket, is actually on the ring. That socket, might itself be a spur, with a spur added on to that one, so best to double-check to be sure....

Isolate all the power, remove the socket in question, disconnect and part the two live wires, then check for continuity between them. Continuity, suggests it is on the ring. You could likewise check the same, on the two neutral wires.

Thanks all.

Thanks harry. I’m quietly confident it’s not a spur in itself as it’s just one of the standard room sockets from plan with nothing else added in that or the adjacent room. Having lived here since new I know no one else has been tinkering. I agree though, can’t be too careful, I’ll check continuity!

Is it possible you have a 2.5mm radial on 32A breaker?

The continuity test, will confirm that too.

To one socket, yes.

I found the EIC which says it’s a ring
