If you have 208 between legs, you have 120 from each leg to neutral (208 divided by 1.73). Assuming a balanced load, this would be 1 KW per leg - 1000 divided by 120 = 8.33 amps per leg.

Your question contradicts itself. If you have 208v, the answer above is correct, 8.33 amps. If you have 480v, you have 3.6 amps.

To calculate the amperage, first convert 3kW to watts (3,000 watts). Then, use the formula P=VI to find the amperage: 3000 watts = 480 volts x I. Solve for I: I = 3000 watts / 480 volts = 6.25 amps.
