3 Phase Electrical Current

For three phase AC Power, the conversation concerning impedance is correct,
along with power factor, and several other factors (which get pretty deep in
math, which make a negligible impact on the current. For general calculations
the Power (in watts) is equal to the square root of 3 (1.732...) times the
current times the voltage. In this case (and I deleted the original message)
Power = 1.732 x 28.2 Amps x 208 volts or something in the 10,159.2 watts or 10 KW.
 If you are thinking about using a generator to power this thing, a 3 phase
generator is expensive, but if you still want to, be sure to pick one that has
at least 11kw CONSTANT USE, not surge rating.
