Your thoughts gentlemen please.

Kitchen RFC.

Double socket, spur down to single socket for fridge.

Spur also from same double socket to SFCU for boiler.

So, in effect, 4 cables into back of double socket.

Any reason why not?

i cant see any problem with what has been done as long as the terminations look like they are holding up but would probably give it a code 4 to cover my arse as i would be surprised if there is anything in the brb showing this as good practice

i would have thought that the reason why you cant spur two sockets out of one existing socket is because of the loading at the terminals
thats why if you want to put more than one socket/twin socket in a radial off a ring,you have to go from a fused spur to limit it.

grandad if the terminals are tight then they arent carrying the load just holding the connection together

mark
the terminals are part of the conductive circuit and designed and sized to carry a certain load.

think terminal block....you can squeeze 2.5 in a 5amp but you wouldnt use it to join a circuit that could carry 15A....tight or not

just playing devils advocate

in a connector there is a chance the block will carry the load because the cables may not touch each other

i would say that from what the regs say, a spur per socket, or a fused spur per socket which can have an unlimited number of sockets from it because the fused spur is limiting the sockets to 13Amps.

The two questions I would ask myself would be

Q1 Is it dangerous? A No
Q2 Does it contravine BS7671? A Not to my knowledge

Jason' s origional question was 'why not?'

So despite the problems that may be involved terminating 4 cables in single terminals, and therefore 'not good practice', I do not know of any reason 'why not'.
