How Many Amps Is 26.5 kW at 240V?

At 240V, 26.5 kW pulls approximately 129.9 amps on AC single-phase (PF 0.85). This is the case typical for residential water heaters, dryers, ranges, EV chargers, and HVAC equipment. Always verify against the equipment nameplate for actual install sizing.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 26.5 ÷ 240 = 26,500 ÷ 240 = 110.42 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

26,500 ÷ (0.85 × 240) = 26,500 ÷ 204 = 129.9 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 129.9A on AC single-phase at 240V, the load sits in the bracket between a 150A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 175A). 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

26.5 kW costs $4.51/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (AC single-phase)

How the line current for 26.5 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	26.5 kW at 240V (AC single-phase)
Resistive (heaters, incandescent)	1	110.42 A
Fluorescent lamps	0.95	116.23 A
LED lighting	0.9	122.69 A
Synchronous motors	0.9	122.69 A
Typical mixed loads	0.85	129.9 A
Induction motors (full load)	0.8	138.02 A
Computers (without PFC)	0.65	169.87 A
Induction motors (no load)	0.35	315.48 A

AC Conversion Comparison

On DC, 26.5kW at 240V draws 110.42A. AC single-phase at PF 0.85 pulls 129.9A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	26,500 ÷ 240	110.42 A
AC Single Phase (PF 0.85)	26,500 ÷ (0.85 × 240)	129.9 A

Frequently Asked Questions

How many amps is 26.5 kW at 240V?expand_more

26.5 kW at 240V draws about 129.9 amps on an AC single-phase circuit at PF 0.85. Alternate cases at the same voltage: 110.42A on DC.

What size breaker would I need for 26.5 kW at 240V?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.

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 much does 26.5 kW cost to run?expand_more

26.5 kW costs $4.51 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $1,081.20 per month.

How does power factor affect the amps for 26.5 kW at 240V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 26.5 kW at 240V draws 110.42A. At PF 0.80 (typical induction motor), the same real power draws 138.02A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.
