Re: help! AW10 going pop

["Paul Helliwell" <g0kao@xxxxxxx>]

Using the formula  "  Power = Volts * Amps  " and transposing
gets " Amps =
Power / Volts " then with the current nominal supply voltage of 230
volts
and the imeersion heater rated at 3000watts then  you are looking at a
minimum 13Amps hence the reason they are usually fed from their own 15A
circuit from the fuse box.

Was an electrician in past life (JIB approved as well)...

Paul
