Extending my BT line

[matt84]

Hi

I have a BT line which comes into the house and connects to the openreach socket with just the blue and white wires, the rest have been cut off.

I need to move the socket. Does anyone know what I'll need in order to extend this so the socket can go in another room?

I'm guessing the cable of course but how to join the two wires and what cable to use?

Thanks!

You're supposed to extend from the detachable front faceplate and not interfere with BT's wiring.

If the master socket is screw terminal use a Block Terminal 80A. If the master socket is IDC terminal use BT 77 or BT 78 and for cable use CW1308.

Thanks. Looks like the A and B 80A. Very helpful.

If your socket is connected using blue & white then good chance there is already a junction box somewhere. In which case replace existing cable with longer length one and avoid extra joins.

There's a grey box outside and the cable comes through the wall straight to the master socket.

Are you saying I could open that up and stick some replacement cw1308 cable in then run it to where I want the master socket?

Thanks

Possibly. You might need some jelly crimps 8A or 8B in the outside box. If it's the old fig 8 drop wire that doesn't work with jelly crimps.
