Going to replace my consumer unit and also place a secondary one in the garage.
I understand it's not good to have 2 RCDs on the same circuit (unless there is discrimiation between them) so I was wondering where would you put one to safeguard the garage: in the main CU or just in the garage?
Does it make much difference how close (in a domestic situation) the RCD is to the point of use?
Thanks
