Shower circuit design.

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

  • I don't have a regs book to hand to check the bit about omitting overload protection, I suspect that Graham is playing Devils Advocate. 

    Last year I did an EICR for a flat that originally had a gas hob and an electric oven supplied by a B16 MCB and a 2.5 mm circuit. The landlord had the gas hob swapped for an electric hob which was connected to the existing circuit. 

    I presume  @davezawadi (David Stone) will tell me that despite being unusable because the circuit breaker tripped if you turned more than one hot plate on along with the oven, it fully complied with the Wiring Regulations and I should not have coded it a a C2 in the EICR.
