underfloor heating

[brumag]

Hi,
i'm trying to connect up underfloor heating and wire in a fused switch for it. But the socket i was going to spur off of already has a spur on the other side of the wall. The cables to the first socket are too short to connect the 2 sockets up so that they are in a ring and then spur off that.
Can i connect the fused switch into the ring directly? or do i need to put another socket into the ring and spur off that? thats the only other way i can see it working. i dont have a crimp set here and shops are miles away.
any suggestions

Yes, make the current spur part of the ring. Then spur to the UFH.

Electric UFH is ghastly expensive to run - dont be fooled by brochures.

thats the problem though. the existing cable(s) wont reach the spur. is there any other way?
thanks for replying btw

Ideally you would crimp a length onto the ring cable and heatshrink them, but I bet you dont have a ratchet crimper. So you CAN use terminal block if you can fit it into the backbox. So on the ring you'd go:

ring cable > joint > thru wall to old spur socket > back through wall to ring socket > ring cable.

Then spur off either socket for your new accessory.

Did you apply for Building Regulations approval before you started?

thanks for all the replys. Im part p registered so building control not necessary.

i just changed the original double socket to 2 single sockets thereby i was able to create a ring circuit with the old spur and then just spurred off one of the sockets.

thanks again
