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

not having any other reel on the van at the time. Or a very long or very well insulated route, or a failure to check the KVA at 1st fix, and precautionary approach in always using the large stuff and smallest breaker just in case. I agree 10mm will almost always be oversize - some houses and small flats seem to have meter tails of about that size.
