Should i install the rccd at the consumer unit in the house , thus protecting the garage supply cable and the garage itself with a 2-way mcb unit in the garage for the lights and socket.
Or should i use an mcb in the house consumer unit to feed the garage and have a 2 -way unit in the garage with a built in rccd , only this way the garage supply cable would not have rccd protection.
Thanks.
