Hi guys this is my first post on this site, i need some help please.
Ive just bought a seperate RCD shower unit for a 9.5kw shower as the consuner unit is not RCD protected. It is a 63A 30mA RCD and includes a 50A MCB. What size supply cable is required from the consumer unit to the RCD and where abouts does the RCD need to go in the circuit.
