Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 205.75 ÷ 208 = 205,747 ÷ 208 = 989.17 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

205,747 ÷ (0.85 × 208) = 205,747 ÷ 176.8 = 1,163.73 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

205,747 ÷ (1.732 × 0.85 × 208) = 205,747 ÷ 306.22 = 671.88 A

Fluorescent lamps	0.95	601.15 A
LED lighting	0.9	634.55 A
Synchronous motors	0.9	634.55 A
Typical mixed loads	0.85	671.88 A
Induction motors (full load)	0.8	713.87 A
Computers (without PFC)	0.65	878.61 A
Induction motors (no load)	0.35	1,631.7 A

AC Conversion Comparison

On DC, 205.75kW at 208V draws 989.17A. AC single-phase at PF 0.85 pulls 1,163.73A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 671.88A per line since the same 205.75kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	205,747 ÷ 208	989.17 A
AC Single Phase (PF 0.85)	205,747 ÷ (0.85 × 208)	1,163.73 A
AC Three Phase (PF 0.85)	205,747 ÷ (1.732 × 0.85 × 208)	671.88 A
