Does a 200 amp 3 phase service equal a total of 600 amps?

Originally Answered: Does a 200 amp 3 phase service equal a total of 600 amps? No, because each one of the three phase wires is supplying amperage for only one third of the time. The power rotates very fast between those three wires, 60 times per second, so that enables the wires to be much smaller than normal.

How do I convert kW to amps?

For any single-phase AC circuit, Current, I = 1000 x kW / (Vac x P.F.) Therefore, amps can be calculated from AC – kW by dividing kW by the product of the RMS value of applied AC voltage and power factor and multiplying it by 1000.
