How Many Amps Is 10.72 kW at 240V?

10.72 kilowatts at 240V works out to roughly 52.54 amps on AC single-phase at PF 0.85. That is typical for residential water heaters, dryers, ranges, EV chargers, and HVAC equipment. See the DC and alternate-phase numbers below for other circuit types.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 10.72 ÷ 240 = 10,718 ÷ 240 = 44.66 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

10,718 ÷ (0.85 × 240) = 10,718 ÷ 204 = 52.54 A

Equipment & Circuit Sizing

Breaker Sizing

Breaker ratings are in amps, not watts, so the real install answer depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) sizes the conductor and OCP at 125% of a continuous load, equivalently 80% of breaker rating), conductor ampacity and temperature rating, ambient and bundling derates, and any motor or HVAC provisions (NEC 430 / 440). At roughly 52.54A on AC single-phase at 240V, the load sits in the bracket between a 60A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 70A). The actual install pick depends on whether the load is continuous and the factors above; a conversion page can't pick a single "right" breaker from the amp draw alone.

Energy Cost

10.72 kW costs $1.82/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (AC single-phase)

How the line current for 10.72 kW at 240V changes with load power factor, on the same AC single-phase circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	10.72 kW at 240V (AC single-phase)
Resistive (heaters, incandescent)	1	44.66 A
Fluorescent lamps	0.95	47.01 A
LED lighting	0.9	49.62 A
Synchronous motors	0.9	49.62 A
Typical mixed loads	0.85	52.54 A
Induction motors (full load)	0.8	55.82 A
Computers (without PFC)	0.65	68.71 A
Induction motors (no load)	0.35	127.6 A

AC Conversion Comparison

On DC, 10.72kW at 240V draws 44.66A. AC single-phase at PF 0.85 pulls 52.54A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	10,718 ÷ 240	44.66 A
AC Single Phase (PF 0.85)	10,718 ÷ (0.85 × 240)	52.54 A

Frequently Asked Questions

How many amps is 10.72 kW at 240V?expand_more

10.72 kW at 240V draws about 52.54 amps on an AC single-phase circuit at PF 0.85. Alternate cases at the same voltage: 44.66A on DC.

What is the formula for kW to amps?expand_more

DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (Volts_L-L × √3 × PF).

How does power factor affect the amps for 10.72 kW at 240V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 10.72 kW at 240V draws 44.66A. At PF 0.80 (typical induction motor), the same real power draws 55.82A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.

What is 10.72 kW in watts?expand_more

10.72 kW equals 10,718 watts. Multiply kilowatts by 1000.

Is 10.72 kW single-phase or three-phase?expand_more

10.72 kW is available in both, but three-phase is more common for commercial HVAC, rooftop units, and motors once you reach this range.
