what amp junction box

[bazaa]

Wanted to move this socket onto another wall use to be a single gang socket coming off the 13a junction box,

The circuit is looking like this as far as I can see from under the floorboards, The CU is under the stairs in the kitchen so i can't tell what cables from the sockets are coming back to the CU but it is 2 lives into a b32 mcb so most likely a ring?

What I wanted to ask was I wanted to replace the single gang socket and add a double gang socket which will supply 2 Tvs + a extension with a CCTV NVR box. The other sockets don't get used much just the odd iPhone charger or laptop sometimes.

Do I use a 4mm cable to the double gang socket that I'm replacing and do I need to get a higher amp junction box?

Also next to the jb use to be a fused spur supplying a floodlight, but that was removed by the electrician and I'm assuming he just added wagos to that part of the circuit to keep the power running to this JB.

2.5mm² T&E cable will be more than adequate.

However, that is an odd arrangement for a ring circuit.
You really need to investigate further.

bad drawing but wago haha i dont know if it is 100% i checked behind the wall but its full of insulation. use to be a fused switch there which was removed so i think the electrician that came just connected the remaining cables there in a wago

that's why i was thinking to use a 4mm cable just incase

will a 13a junction box suffice or should i get a higher amp

Well - a double socket could have 26A plugged in so higher than that.

However you really must investigate the circuit wiring.
From your drawing it looks like one socket on the ring and three spurs - or the ring has been split at the left hand socket.

Photos would be better.

attached the images, the pic you see under the floorboards, left one is the one with the junction box in the paint drawing(use to supply a single gang socket)

one of cables is going into a double socket, and then the other one Is somewhere behind the plastered wall (there use to be a fused switch there for a floodlight but we got rid of the floodlight so the electrician removed the fuse switch.

Socket with 2 wires, then other socket thats opened is the one on the far right in the pic. Wire with that butchered taping and white box is the junction box that the single socket was on, that was removed recently, I wanted to connect the 4mm to this white jb and put the socket on the other wall for a TV.

added the gif, at the start of the gif, left of that socket use to be the fuse spur, but now its probably wagos or something.

so 2 gang socket, if i plug a 13amp socket for the tv, then a extension socket which will have a cctv nvr box and a led tv on it, will a 32 amp junction box suffice for a 4mm cable
