New member, straight in with a question

In truth,to accurately guage the size and type,there are many other factors to be considered,not least,installation earthing,duty cycles,fuelling and noise...

Just considering the possible running load,would only ensure reliability,for a day

If the genny is powering 3 motors, that "are pulling about 61a" each, how are the motors controlled (DOL, inverter) and do they all start at the same time?
Would you not need a bigger genny for the start-up of the motors?

Sorry spoon, I was given the wrong info, the power is for heating not motor and I can get them switched on and off individually via separate controls.

I appreciate that there is more to it. This is for film production purposes so will only be there a week so not really a problem if we overkill it with a bigger genny then needed.
I have got a 200kva that supplies 250a each phase so I'm going to suggest using just three of the 3 phase 63a heaters as although the Kva rating is ok, we will be pushing about 183a down each phase from my calcs
