i have fitted a new 9.5kw shower and run 10mm twin and earth, i am just about to fit an external 63A 30mA Rcd with a 50A MCB.
My question is can i come straight out of a spare 40A MCB on my board with my live and them into the RCD and get my Neg and Earth from the buzz bars within my Consumer unit. Obviously this would be in 10mm.
