Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 573.82 ÷ 480 = 573,822 ÷ 480 = 1,195.46 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

573,822 ÷ (0.85 × 480) = 573,822 ÷ 408 = 1,406.43 A

AC Three Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

573,822 ÷ (1.732 × 0.85 × 480) = 573,822 ÷ 706.66 = 812 A

Fluorescent lamps	0.95	726.53 A
LED lighting	0.9	766.89 A
Synchronous motors	0.9	766.89 A
Typical mixed loads	0.85	812 A
Induction motors (full load)	0.8	862.75 A
Computers (without PFC)	0.65	1,061.85 A
Induction motors (no load)	0.35	1,972 A

AC Conversion Comparison

On DC, 573.82kW at 480V draws 1,195.46A. AC single-phase at PF 0.85 pulls 1,406.43A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 812A per line since the same 573.82kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	573,822 ÷ 480	1,195.46 A
AC Single Phase (PF 0.85)	573,822 ÷ (0.85 × 480)	1,406.43 A
AC Three Phase (PF 0.85)	573,822 ÷ (1.732 × 0.85 × 480)	812 A
