I know that to be precise you must calculate the load of all equipment being fed by a generator, with special attention given to motor LRA (start amps).

Though this wouldn't be realistic (100% pure resistive load), do I have the most basic load calculation formula for a generator correct?

Single Phase: Amps X Volts = Watts X1000 = Kilowatts

Three phase: Amps X Volts X 1.73 (Power Factor) = Watts X1000 = Kilowatts

Now, with generators being rated with kvA instead of kilowatts, it would be....
Single phase: Volts X Amps / 1000 = kvA

3 ph: Volts X Amps X 1.73 / 1000 = kvA

Are these formulas correct?

I * E = W/1000 = kw.

DIVIDE not MULTIPLY
