2 new spurs via junction box from ring main

[pedmon]

My Master Bedroom only has 1 double socket. This socket is to the rear of the right side of the bed. I wish to add another double socket at the left rear side of the bed. This is run a clock and a lamp mainly. So we will end up with socket at either side of bed behind bde side cabinets.

The orignal socket is on a ring main (has 2 sets twin and earth going to it).

I am going to put a junction box from the orignal double socket then create a spur at the other side of the bed. I already have the new socket in the wall (not wired up yet)

I also need another double socket opposite the orignal socket about 8 feet away. This runs with the joists so only 1 floorboard to lift for that one. Might as well get two done while I can.

So my plan is to create 2 spurs with a junction box off the original double socket on the ring main.

Just a few questions:

1) Is this the best way to do it?
2) Is 23A twin and earth cable adequate for the job. Says its for mains sockets so I presume so.
3) Do all suprs need to be fused? If so what amps (13A I presume). And would these be fused at the socket using fused sockets or fused junction box.

According to many posts I have read and electrical guides this seems ok. To run a small radial circuit of 2 sockets from the ring main.

you arent running any radials, 2 spurs. a spur with simply a double socket at the end doesn't need a fuse.

Where is this junction box going?
*directly on the ring main? (cut into existing cable near existing socket) (safe)
*from a new cable from the existing socket? (not safe) (what i think you proposed)

will it be accessible? Wouldnt it be better to extend the ring main rather than run all these spurs all over, making a mess, and having inaccessible junction points?

1. no. extend the ring.
2. 23A twin and earth? what's this? 2.5mm² cable ("socket cable") has many different ratings. it is only rated at 23A when it is clipped to a wall and well ventilated (i think) and its rating drops substantially when run in insulation or grouped.
3. no.

Was going to go from existing dbl socket. But I shall extend the ring main

(i shall find the cable from the existing dbl socket and extend from there).

I suppose that way I can add my 2 dbl sockets and continue the ring. Won't exactly be ring shaped so to speak (but that cant be hepled). Then each socket is going to end up with a pair of 3 core cables to it. (i.e all attatched to the ring main)

Juntion box is going under the floor boards. The JB will allow me to connect to the existing cable from the ring main. Need some way of connecting to existing wiring

I can extend the ring. Means a bit more work. But if its safer then thats fair enough.

Yes its 2.5mm cable.

i have drawn a diagram to clear up any confusions.

You will, of course make sure of that, won't you, and not just assume that 2 cables at a socket, or indeed 2 cables at the origin mean that it can only be a ring....

That looks the same as what I was going to do yes. Just rotated 90 degrees anti clockwise.

Yes Im going to check that. Cause it could be just be a spur that joins to another existing socket.

Not sure this is what is meant by accessible!!

Well no probably not. Im sure it means is the ring main accessible.....not sure yet (hopefully, will find out at weekend when we have some light and i can turn the mains off)
