Hi everyone.
I want to fit a 10.5kw electric shower. I have a new consumer unit with an unused MCB rated at 40 amps. The shower I'm thinking of needs 10mm cable. I already have a 40 amps 30mA RCD which I can add to the shower circuit.
My question is... will a 40 amp MCB and 40 amp 30 mA RCD be OK for use with a 10.5kW shower which uses 10mm cable?
