Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 752 ÷ 575 = 752,000 ÷ 575 = 1,307.83 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

752,000 ÷ (0.85 × 575) = 752,000 ÷ 488.75 = 1,538.62 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

752,000 ÷ (1.732 × 0.85 × 575) = 752,000 ÷ 846.52 = 888.32 A

Power Factor Reference (AC three-phase)

How the line current for 752 kW at 575V 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	752 kW at 575V (AC three-phase)
Resistive (heaters, incandescent)	1	755.07 A
Fluorescent lamps	0.95	794.81 A
LED lighting	0.9	838.97 A
Synchronous motors	0.9	838.97 A
Typical mixed loads	0.85	888.32 A
Induction motors (full load)	0.8	943.84 A
Computers (without PFC)	0.65	1,161.65 A
Induction motors (no load)	0.35	2,157.35 A

AC Conversion Comparison

On DC, 752kW at 575V draws 1,307.83A. AC single-phase at PF 0.85 pulls 1,538.62A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 888.32A per line since the same 752kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	752,000 ÷ 575	1,307.83 A
AC Single Phase (PF 0.85)	752,000 ÷ (0.85 × 575)	1,538.62 A
AC Three Phase (PF 0.85)	752,000 ÷ (1.732 × 0.85 × 575)	888.32 A

Frequently Asked Questions

How many amps is 752 kW at 575V?expand_more

752 kW at 575V draws about 888.32 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 1,307.83A on DC, 1,538.62A on AC single-phase.

What is 752 kW in watts?expand_more

752 kW equals 752,000 watts. Multiply kilowatts by 1000.

Is 752 kW single-phase or three-phase?expand_more

752 kW is typically three-phase in commercial and industrial settings.

What size breaker would I need for 752 kW at 575V?expand_more

This is a sizing question, not a conversion question, and there is no single correct answer from a page like this. Breaker selection depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) applies the 125% continuous-load rule), the conductor ampacity and temperature rating, any NEC 430/440 motor or HVAC provisions, and local code interpretation. Use the nameplate and a licensed electrician for the real install value; use this page only for the current-draw estimate that feeds into that process.

How does three-phase affect the amps for 752 kW?expand_more

Three-phase at 575V draws 888.32A per line versus 1,538.62A single-phase. Less current per conductor means smaller wire and lower I²R losses.

This calculator provides estimates for reference purposes only. Always consult a licensed electrician and verify compliance with the National Electrical Code (NEC) and local electrical codes before performing any electrical work.
