Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 424.01 ÷ 208 = 424,006 ÷ 208 = 2,038.49 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

424,006 ÷ (0.85 × 208) = 424,006 ÷ 176.8 = 2,398.22 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

424,006 ÷ (1.732 × 0.85 × 208) = 424,006 ÷ 306.22 = 1,384.62 A

Power Factor Reference (AC three-phase)

How the line current for 424.01 kW at 208V changes with load power factor, on the same AC three-phase circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	424.01 kW at 208V (AC three-phase)
Resistive (heaters, incandescent)	1	1,176.92 A
Fluorescent lamps	0.95	1,238.87 A
LED lighting	0.9	1,307.69 A
Synchronous motors	0.9	1,307.69 A
Typical mixed loads	0.85	1,384.62 A
Induction motors (full load)	0.8	1,471.15 A
Computers (without PFC)	0.65	1,810.65 A
Induction motors (no load)	0.35	3,362.64 A

AC Conversion Comparison

On DC, 424.01kW at 208V draws 2,038.49A. AC single-phase at PF 0.85 pulls 2,398.22A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 1,384.62A per line since the same 424.01kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	424,006 ÷ 208	2,038.49 A
AC Single Phase (PF 0.85)	424,006 ÷ (0.85 × 208)	2,398.22 A
AC Three Phase (PF 0.85)	424,006 ÷ (1.732 × 0.85 × 208)	1,384.62 A
