I'm looking to power my garage for a couple of sockets and lighting. Its about 10mtrs from the house and i aim to use SWA cable and a 2 way garage unit with RCD protection. Its quite an old house (1960s) and has no RCD protection at the cons unit (MEM) and all of the fuseways are already taken. I know that i require RCD protection for the garage, but was wondering which was the best way to wire this?
Shall i take a SWA supply from the meter cupboard outside via a henley block and switchfuse unit and run it to the garage to connect to the 2way board with RCD protection?
Should the RCD be installed in the meter cupboard, via henley block before it goes to the garage supply?
I hope ive explained this correctly??
