Evening all - got a question that i think i no tje answer but need some assurance!!
Putting a sub main (garage CU) with standard sockets and lights.
Feed to garage CU from suitable MCB in main board that IS RCD protected.
Now........testing ... Most garage CU come with RCD, my understanding is RCD in series a pain so looking for the correct way to test - or is it easier to get a sub main with a 100A main switch no RCD? Thanks
