Wiring a Socket Using 2.5mm Twin Single Earth Cable Ask questions and find answers to many subjects relating to electrics and electrical work

[Salty37]

Flummoxed by what should be a simple wiring job! Trying to run the cable from an existing double socket a distance of about 8m to a new double socket in the garage. Existing comes from an RCD with 2 red, 2 blue and 2 earth into the socket. The second set of wires feeds 2 on/switches serving a water feature and the greenhouse. Couldn’t get 3 wires in to this socket ( didn’t seem safe anyway) so opted to put a 3pin plug on the end of the cable. Result - Nothing at the new socket! Plug checked. Fuzes checked. Existing socket checked and serving other devices
Advice please

Old colours red and black, new colours brown and blue, so it would seem a mixture old and new which is not normal, so would guess you have not got all cores.

Normally a non fuses spur is limited to 3 meters, so at 10 meters should be a fused connection unit (FCU) so may be simply blown a fuse?

Many thanks. An FCU it is then. Will report success..........or otherwise.

Inaccurate info given. Should have said 2 red and 2 black into the existing switch. New cable is of course 1 brown, 1 blue and an earth. How then do I create a further double socket some 8m on the other side of the garage?

To add a spur, you connect the brown with the reds, and the blue with the blacks the earths all go together. They should also be covered in green/yellow sleeving.

At the new socket Brown is live, Blue is neutral and earth is earth.

Please tell me you are connecting to an existing SOCKET not as you typed, switch.

Thanks. Got all of that. Puzzled by talk of an FCD earlier in the thread. I am looking to install a socket 8m away from the existing one so appreciate the advice about 2.5m cable and the need for fuses. That said, isn’t a FCD a switch? Do I need to install that between the existing and new sockets?

[Mr White]

FCD? or is that another TYPO?

I take it you mean (as ericmark said) FCU?

No its not just a switch, it is actually a device to hold/carry a fuse, some have switches, some don't. The fuse is the important part.
