Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 815.52 ÷ 575 = 815,520 ÷ 575 = 1,418.3 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

815,520 ÷ (0.85 × 575) = 815,520 ÷ 488.75 = 1,668.58 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

815,520 ÷ (1.732 × 0.85 × 575) = 815,520 ÷ 846.52 = 963.36 A

LED lighting	0.9	909.84 A
Synchronous motors	0.9	909.84 A
Typical mixed loads	0.85	963.36 A
Induction motors (full load)	0.8	1,023.57 A
Computers (without PFC)	0.65	1,259.77 A
Induction motors (no load)	0.35	2,339.58 A

AC Conversion Comparison

On DC, 815.52kW at 575V draws 1,418.3A. AC single-phase at PF 0.85 pulls 1,668.58A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 963.36A per line since the same 815.52kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	815,520 ÷ 575	1,418.3 A
AC Single Phase (PF 0.85)	815,520 ÷ (0.85 × 575)	1,668.58 A
AC Three Phase (PF 0.85)	815,520 ÷ (1.732 × 0.85 × 575)	963.36 A
