Even with my grade C in A Level physics I can work out that a 10.5 KW shower pulls a tad more than 45 Amps.
Spark123 said:The power rating for a shower is usually stated at 240v which equates to a tad under 44A for a 10.5kw, at 230v the power output is reduced to somewhere around 9.6kw.
You should have got an answer of 42A, not a tad more than 45....Fair point. Just checked the manufacturer's spec and it's 43.8A at 240V. I worked it out using 230V
Ohm's Law was O-Level physics, IIRC...Also, my memory fails me. I got a Grade D in A-Level Physics, not a C. One good reason why I never became an electrician.

(you should not be running a breaker on its tripping curve).
