How Many Amps Is 11.07 kW at 208V?

11.07 kW at 208V draws about 36.16 amps on an AC three-phase circuit at PF 0.85, typical for commercial HVAC, industrial motors, rooftop units, and three-phase panel loads. Actual current varies with equipment power factor and duty cycle.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 11.07 ÷ 208 = 11,074 ÷ 208 = 53.24 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

11,074 ÷ (0.85 × 208) = 11,074 ÷ 176.8 = 62.64 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

11,074 ÷ (1.732 × 0.85 × 208) = 11,074 ÷ 306.22 = 36.16 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 36.16A on AC three-phase at 208V, the load sits in the bracket between a 40A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 50A). 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

11.07 kW costs $1.88/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (AC three-phase)

How the line current for 11.07 kW at 208V 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	11.07 kW at 208V (AC three-phase)
Resistive (heaters, incandescent)	1	30.74 A
Fluorescent lamps	0.95	32.36 A
LED lighting	0.9	34.15 A
Synchronous motors	0.9	34.15 A
Typical mixed loads	0.85	36.16 A
Induction motors (full load)	0.8	38.42 A
Computers (without PFC)	0.65	47.29 A
Induction motors (no load)	0.35	87.82 A

AC Conversion Comparison

On DC, 11.07kW at 208V draws 53.24A. AC single-phase at PF 0.85 pulls 62.64A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 36.16A per line since the same 11.07kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	11,074 ÷ 208	53.24 A
AC Single Phase (PF 0.85)	11,074 ÷ (0.85 × 208)	62.64 A
AC Three Phase (PF 0.85)	11,074 ÷ (1.732 × 0.85 × 208)	36.16 A

Same kW, Other Voltages

Each destination page leads with the interpretation most common for that voltage, so the amps shown below use the same basis as the page you'd land on: single-phase for residential voltages, three-phase for commercial/industrial panel voltages, DC for low-voltage.

Frequently Asked Questions

How many amps is 11.07 kW at 208V?expand_more

11.07 kW at 208V draws about 36.16 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 53.24A on DC, 62.64A on AC single-phase.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 11.07 kW is easier to express than 11,074W. The math is identical, just scaled by 1000.

Is 11.07 kW single-phase or three-phase?expand_more

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

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).

What size breaker would I need for 11.07 kW at 208V?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.

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.
