Hello,
I want to add an extra socket in my garage as I only have one existing. The only thing that's puzzling me a bit is that the one that is there is one of those metaclad sockets with RCD built in.
This connects to the garage CU that has 16A for the socket, 6A for the light and an RCD protecting both.
This garage CU connects back to the house via some SWA cable and is on the RCD side of the board there too.
I'm a bit curious about the set-up. I guess the RCD in the house protects the cable run to the garage. The RCD in the garage possibly serves no purpose but is it good practice to have another more local to socket? And the RCD built into the socket serves no purpose at all, is that right?
And the purpose of this is just to confirm that I'm safe to buy a standard socket with no RCD to connect to the one that's there?
Thanks for reading.
