Need to add another single socket

[chiz]

Hi,

Newbie here. Was told this is the best forum to ask an electrical question, so here goes.

I have a spur off a double socket on a ring main - the spur goes to a 30A junction box (under floor boards) and then on to a FCU then a single socket. The FCU carries a 13A fuse.

The junction box i believe was put in place due to the spur cable being too short, so the JB was added to allow further length to the spur.

Now my question is - can i add another socket off the junction box as long as the cable that goes from the JB goes to a 13A FCU, then a single socket.

The cable is 2.5mm T&E. The house is a small house and the cable from the ring main to the spur is at most 5m in length. Its from the Living room, to the above bedroom.

Personally, I think everything is ok, as everything is fused and mathmatically correct, but i still may be wrong

Any help is greatly appreciated

Its a bit odd  .  The 13A  spur  needs to be in the leg coming from your twin socket  really,   then the possible load  is limited to 13A  .      Why not fit new twin sockets , in today's world a single socket is not much use .

Yes the original leg from the double socket had a 13a fused spare (black ink in drawing) I want to add another socket (green ink) or should I take 2nd socket from the original FCU (black ink) then that will limit all to 13amp.

I may fit twin sockets to. Thank for your reply btw
