Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 753.25 ÷ 575 = 753,250 ÷ 575 = 1,310 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

753,250 ÷ (0.85 × 575) = 753,250 ÷ 488.75 = 1,541.18 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

753,250 ÷ (1.732 × 0.85 × 575) = 753,250 ÷ 846.52 = 889.8 A

Fluorescent lamps	0.95	796.14 A
LED lighting	0.9	840.37 A
Synchronous motors	0.9	840.37 A
Typical mixed loads	0.85	889.8 A
Induction motors (full load)	0.8	945.41 A
Computers (without PFC)	0.65	1,163.58 A
Induction motors (no load)	0.35	2,160.94 A

AC Conversion Comparison

On DC, 753.25kW at 575V draws 1,310A. AC single-phase at PF 0.85 pulls 1,541.18A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 889.8A per line since the same 753.25kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	753,250 ÷ 575	1,310 A
AC Single Phase (PF 0.85)	753,250 ÷ (0.85 × 575)	1,541.18 A
AC Three Phase (PF 0.85)	753,250 ÷ (1.732 × 0.85 × 575)	889.8 A
