How Many Amps Is 10.6 kW at 208V?

10.6 kilowatts at 208V works out to roughly 34.61 amps on AC three-phase at PF 0.85. That is typical for commercial HVAC, industrial motors, rooftop units, and three-phase panel loads. 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 × 10.6 ÷ 208 = 10,600 ÷ 208 = 50.96 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

10,600 ÷ (0.85 × 208) = 10,600 ÷ 176.8 = 59.95 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

10,600 ÷ (1.732 × 0.85 × 208) = 10,600 ÷ 306.22 = 34.61 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 34.61A on AC three-phase at 208V, the load sits in the bracket between a 35A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 45A). 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

10.6 kW costs $1.80/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (AC three-phase)

How the line current for 10.6 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	10.6 kW at 208V (AC three-phase)
Resistive (heaters, incandescent)	1	29.42 A
Fluorescent lamps	0.95	30.97 A
LED lighting	0.9	32.69 A
Synchronous motors	0.9	32.69 A
Typical mixed loads	0.85	34.61 A
Induction motors (full load)	0.8	36.78 A
Computers (without PFC)	0.65	45.27 A
Induction motors (no load)	0.35	84.06 A

AC Conversion Comparison

On DC, 10.6kW at 208V draws 50.96A. AC single-phase at PF 0.85 pulls 59.95A because reactive current is added on top of the real power. Three-phase at the same voltage needs only 34.61A per line since the same 10.6kW is shared across three conductors instead of one.

Circuit Type	Formula	Result
DC	10,600 ÷ 208	50.96 A
AC Single Phase (PF 0.85)	10,600 ÷ (0.85 × 208)	59.95 A
AC Three Phase (PF 0.85)	10,600 ÷ (1.732 × 0.85 × 208)	34.61 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 10.6 kW at 208V?expand_more

10.6 kW at 208V draws about 34.61 amps on an AC three-phase circuit at PF 0.85. Alternate cases at the same voltage: 50.96A on DC, 59.95A on AC single-phase.

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 10.6 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.

How many amps does a 10.6 kW EV charger draw at 208V?expand_more

At 208V, a 10.6 kW EVSE draws about 59.95A on AC single-phase at PF 0.85. This is Level 2 territory, the standard residential (240V) or commercial (208V) AC charging tier covered by NEC Article 625. Home Level 2 units are typically 7.2 to 19.2 kW (30-80A); anything above that is usually commercial hardware or DC fast charging. Although the hero on this page shows the three-phase figure for 208V as the primary interpretation, real-world 208V commercial Level 2 EVSE is almost always wired single-phase across two wye legs, so the single-phase number above is the one a charger installer would use.

Is 10.6 kW single-phase or three-phase?expand_more

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