Hi
Problem with garage supply
I have a small consumer unit in Garage. 1x 6a and 2 x 16a MCBs
And. 63a RCD
For no obvious reason the RCD trips
I’ve isolated all circuits from CU.
I.e. removed all neutrals and internal earths and turned MCBs off
Still trips for no apparent reason
Garage is fed via 6mm twin and Earth cable from 32a mcb in main house CU. Also has a separate 6mm earth.
The mcb in the house is not RCD fed.
The rest of the house is controlled by its own RCD.
The house RCD has only ever tripped if anything in the house is a problem.
Any thoughts please?
