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

I carried out an electrical inspection and test today and will issue an E.I.C.R. Just out of interest, and because I could not see a rating label on an unfamiliar electric shower protected by a 45 Amp M.C.B., I carried out a load test with a clamp meter with the shower set at maximum. The meter read 37 Amps. Why a 45 Amp M.C.B. in this instance? The whole installation is protected by a 50 Amp M.C.B.
I would have used a 40 Amp M.C.B. for the shower.
