Actually this is a very good question. Reason I have wired a couple that had 2 16 amp supplys, one for the blowers and one for the heater. To be fair though they were considered large, the average whirlpool is 4 kw, also agree with hawkmoon and trev about ignoring the plumber and getting proper advice.Is the flex just suppling the pump for the blowers I take it there isn't a heater fitted as well.
Can you see why I gave you a bit of a bashing in the last thread now Dean when you were talking about a 10mm2 cable? good luck fella I am done here now, just be careful.The flex is connected to an ip rated box which has some components inside. this is where the supply is connected too. Board has 2 rcds covering 4 circuits each.
