I came across an interesting one the other day.
It was a faulty Triton shower rated at 9.5KW.
However the MCB for it in the consumer unit was rated at 32amps. (Definitely the shower one as when switched off the power to the shower was off.)
Now if you take 9500watts and divide by 240 volts you would get 39.58 amps (of course the rating should be even higher if you work on 230Volts)
So how was the shower working on a 32 amp MCB?
