Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 200.78 ÷ 208 = 200,784 ÷ 208 = 965.31 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

200,784 ÷ (0.85 × 208) = 200,784 ÷ 176.8 = 1,135.66 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

200,784 ÷ (1.732 × 0.85 × 208) = 200,784 ÷ 306.22 = 655.67 A

Fluorescent lamps	0.95	586.65 A
LED lighting	0.9	619.25 A
Synchronous motors	0.9	619.25 A
Typical mixed loads	0.85	655.67 A
Induction motors (full load)	0.8	696.65 A
Computers (without PFC)	0.65	857.42 A
Induction motors (no load)	0.35	1,592.34 A

AC Conversion Comparison

On DC, 200.78kW at 208V draws 965.31A. AC single-phase at PF 0.85 pulls 1,135.66A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 655.67A per line since the same 200.78kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	200,784 ÷ 208	965.31 A
AC Single Phase (PF 0.85)	200,784 ÷ (0.85 × 208)	1,135.66 A
AC Three Phase (PF 0.85)	200,784 ÷ (1.732 × 0.85 × 208)	655.67 A
