Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 240.34 ÷ 208 = 240,340 ÷ 208 = 1,155.48 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

240,340 ÷ (0.85 × 208) = 240,340 ÷ 176.8 = 1,359.39 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

240,340 ÷ (1.732 × 0.85 × 208) = 240,340 ÷ 306.22 = 784.84 A

Fluorescent lamps	0.95	702.23 A
LED lighting	0.9	741.24 A
Synchronous motors	0.9	741.24 A
Typical mixed loads	0.85	784.84 A
Induction motors (full load)	0.8	833.9 A
Computers (without PFC)	0.65	1,026.33 A
Induction motors (no load)	0.35	1,906.05 A

AC Conversion Comparison

On DC, 240.34kW at 208V draws 1,155.48A. AC single-phase at PF 0.85 pulls 1,359.39A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 784.84A per line since the same 240.34kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	240,340 ÷ 208	1,155.48 A
AC Single Phase (PF 0.85)	240,340 ÷ (0.85 × 208)	1,359.39 A
AC Three Phase (PF 0.85)	240,340 ÷ (1.732 × 0.85 × 208)	784.84 A
