am2 motor overload

[Darkwood]

400*sqrt(3) = 693. Or, if you prefer, 3*230 with a rounding error! Watts per amp of line current into a 3-phase resistive load.

I was holding a carrot out for feedback, wondered why he had posted it in a thread about motors so I took a position of confusion, idea was for him to look it up and realise he had posted the wrong formula (best way to learn imho), my response back to his reply would have corrected him regarding resistive load calcs against that of an inductive motor calc' but he never posted a reply and I forgot about it...
