I've put up a couple of sets of lights on the tree outside our house and when the big switch-on happens i will be protecting them with a circuit breaker. However, do i need a circuit breaker on each set of lights or can i plug a 2-gang trailing socket (internally) into a circuit breaker and plug both sets of lights into the trailing socket thus protecting both sets of lights with a single circuit breaker?

The kids love the house all decorated up but i don't want to turn it from christmas celebrations to a very late Guy Fawkes night event!!!

I'm assuming that by circuit breaker you mean a plug in RCD?
Do your sockets not have RCD protection already?

If you already have RCD protection on the sockets it is pointless using a plug in RCD.

Otherwise yes you can plug the extension into the RCD socket
kkynaston - thanks for the reply.

No our existing fuse board has the old wired fuse boxes so no RCD and yes i do mean the plug-in style RCD.

We're getting a new CU in the new year when we wire up the new circuits for our loft conversion so next christmas all our sockets will be RCD protected.
