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

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.
I shall too!
I am not sure that BS 7671 says that you have to provide enough power. The circuit was perfectly safe, but the unwanted tripping would be a real nuisance. The circuit complied with 433.1.1 when it was erected. 133.2 may be relevant, but it certainly wouldn't merit more than C3. Overall, non-compliance is not obvious, so no code from me.
