Hi I have a simple ring going round the attic with 4 double sockets, I would like to drop a supply down to an alarm, cut ring and use a junction box or try connecting into an existing socket ?
So would you cut the ring or try adding to the socketYou can get 3 x 2.5mm into a socket. Just make sure all three wires are secure in the socket as sometimes 1 of them doesn't seem to grip properly occasionally.
You can take one spur off a ring without fcu ?
and have 3A fuse by alarm
Some would say you can even use 1.5mm cable if it’s a direct route
Indeed, and that's probably what most people would do (originating the spur at an existing socket).You can take one spur off a ring without fcu ? ... and have 3A fuse by alarm
In virtually all cases that "some" should include anyone capable of reading and understanding BS7671 (rather than the 'informative' Appendix 15 thereof) - and (although I'm not totally sure what you mean), they wouldn't need to qualify it with "if it’s a direct route".Some would say you can even use 1.5mm cable if it’s a direct route
