Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 982 ÷ 480 = 982,000 ÷ 480 = 2,045.83 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

982,000 ÷ (0.85 × 480) = 982,000 ÷ 408 = 2,406.86 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

982,000 ÷ (1.732 × 0.85 × 480) = 982,000 ÷ 706.66 = 1,389.6 A

Power Factor Reference (AC three-phase)

How the line current for 982 kW at 480V 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	982 kW at 480V (AC three-phase)
Resistive (heaters, incandescent)	1	1,181.16 A
Fluorescent lamps	0.95	1,243.33 A
LED lighting	0.9	1,312.4 A
Synchronous motors	0.9	1,312.4 A
Typical mixed loads	0.85	1,389.6 A
Induction motors (full load)	0.8	1,476.45 A
Computers (without PFC)	0.65	1,817.17 A
Induction motors (no load)	0.35	3,374.75 A

AC Conversion Comparison

On DC, 982kW at 480V draws 2,045.83A. AC single-phase at PF 0.85 pulls 2,406.86A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 1,389.6A per line since the same 982kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	982,000 ÷ 480	2,045.83 A
AC Single Phase (PF 0.85)	982,000 ÷ (0.85 × 480)	2,406.86 A
AC Three Phase (PF 0.85)	982,000 ÷ (1.732 × 0.85 × 480)	1,389.6 A
