How Many Amps Is 11,000 Watts at 230V?

11,000 watts at 230V draws 47.83 amps on an AC single-phase resistive circuit. Reactive or motor loads at the same real power draw more current than the resistive figure because of the power-factor penalty.

At 47.83A, the NEC 210.19(A) continuous-load sizing math (125% of the load, equivalently 80% of the breaker rating) points to a 60A breaker as the smallest standard size that covers this load continuously. A 50A breaker is the smallest standard size the raw current fits under, but it is non-continuous-only at this load.

Assumes an AC single-phase resistive load at PF 1.0. Typing a commercial L-L voltage (208/400/480V) re-routes the result to three-phase; 277V stays on single-phase because it's the L-N lighting leg of a 480Y/277V wye; 12/24V re-routes to DC.

Formulas

DC: Watts to Amps

I_(A) = P_(W) ÷ V_(V)

11,000 ÷ 230 = 47.83 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

11,000 ÷ (0.85 × 230) = 11,000 ÷ 195.5 = 56.27 A

Circuit Sizing

Breaker Sizing

NEC 240.6(A) standard ampere ratings for branch-circuit and feeder breakers start at 15, 20, 25, 30, 35, 40, 45, and 50A and continue at 60A and above for feeder and large-appliance circuits. At 47.83A, the smallest standard breaker the raw current fits under is 50A, but that breaker only covers 50A non-continuously; NEC 210.19(A) requires conductor and OCP sized at 125% of any continuous load (equivalently 80% of breaker rating), so for a continuous load the smallest compliant breaker is 60A. Final selection still depends on the equipment nameplate, whether the load is continuous, conductor ampacity, and local code.

Energy Cost

Running 11,000W costs approximately $1.87 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $14.96 for 8 hours or about $448.80 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 11,000W at 230V is 47.83A. On an AC circuit with a power factor of 0.85, the current rises to 56.27A because reactive current flows alongside the real-power current.

Circuit Type	Formula	Result
DC	11,000 ÷ 230	47.83 A
AC Single Phase (PF 0.85)	11,000 ÷ (230 × 0.85)	56.27 A

Power Factor Reference

Power factor is the main reason 11,000W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 47.83A at 230V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 11,000W pulls 59.78A. That is an extra 11.96A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Resistive (heaters, incandescent)	1	47.83 A
Fluorescent lamps	0.95	50.34 A
LED lighting	0.9	53.14 A
Synchronous motors	0.9	53.14 A

Induction motors (full load)	0.8	59.78 A
Computers (without PFC)	0.65	73.58 A

Frequently Asked Questions

How many amps is 11,000W at 230V? expand_more

11,000W at 230V draws 47.83 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 47.83A on DC, 56.27A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

How much does 11,000W cost to run per hour? expand_more

At the US residential average of $0.17/kWh (last reviewed April 2026), 11,000W costs $1.87 per hour and $14.96 for 8 hours. Rates vary by utility and time of day.

What kind of outlet does a 11,000W appliance need on 230V? expand_more

230V is the IEC single-phase residential nominal voltage, so outlet type depends on region rather than a single universal standard. Common residential receptacle types: Schuko (CEE 7/3, 16 A) across most of continental Europe; French CEE 7/5 (16 A) in France and parts of Belgium; UK BS 1363 (13 A fused plug) in the UK, Ireland, and former British-standard regions; Italian Type L (10/16 A) in Italy; AS/NZS 3112 (10 A) in Australia and New Zealand; IS 1293 Type D/M (6/16 A) in India. At 11,000W on 230V the current is 47.83A, which fits a standard residential socket in any of these regions (past the typical plug-and-socket limit; the load needs a dedicated hardwired circuit). Verify against the appliance's spec sheet, the local wiring regulations, and the actual installed receptacle type.

What is the 80% continuous load rule for 11,000W? expand_more

NEC 210.19(A) sizes the conductor and overcurrent device at not less than 125% of any continuous load (a load that runs three hours or more), equivalently 80% of the breaker rating. At 47.83A (the current the branch conductors actually carry on AC single-phase at PF 1.0 (resistive)), the minimum breaker that satisfies this is 60A under typical assumptions. Brief non-continuous use can run closer to the full breaker rating, but space heaters, EV chargers, and long-running appliances should be sized for the continuous case.

What 230V circuit size does 11,000W need? expand_more

At 47.83A the load is past the typical residential IEC branch range and needs a dedicated industrial circuit sized by a qualified electrician against the equipment nameplate and the local wiring regulations (BS 7671, DIN VDE, AS/NZS 3000, etc.). 230V is the IEC single-phase residential nominal voltage used across Europe, the UK, most of Asia, Australia, and New Zealand; exact breaker selection and wiring rules follow the local regulations (BS 7671 in the UK, CENELEC HD 60364 / IEC 60364 across Europe, AS/NZS 3000 in Australia / NZ).
