Default 20a rccb
Is the any reason that I can't find 20A 4 pole RCCB to buy?. The minimum that I could find is 25A. Im doing spa room with sauna & jacuzzi. Sauna unit required 3 phases (6KW). As this is special location I need to RCD the all lot.

RCD must not be less, then automat.switch of the same line. 16A A.S.-so RCD should be from 16A and bigger. Regards.

Its better to be guided by the Manufacturers instructions on what they specify for their own kit. 20A for 6kW ?

A sparky friend of mine recently had a bit of an issue wiring a hot tub. It clearly stated in the manufacturer instructions that no RCD's were to be used due to the earth leakage of the tub. It wasn't british equipment.
