Shower circuit design.

Sparkingchip

Why would an electrician install a 10 mm twin and earth circuit protected by a B32 MCB for a 8.5 kW shower?

    I’m okay with running 10 mm for a new shower circuit, it may be OTT, but not an issue as it’s rated at 52 amps.

    Actually the circuit could possibly have a 45 or 50 amp MCB rather than a 40 amp, but the installer chose a 32 amp MCB.
