How Many Amps Is 2,004 Watts at 220V?

2,004 watts at 220V draws 9.11 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 9.11A, the NEC 210.19(A) continuous-load sizing math (125% of the load, equivalently 80% of the breaker rating) points to a 15A breaker as the smallest standard size that covers this load continuously.

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)

2,004 ÷ 220 = 9.11 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

2,004 ÷ (0.85 × 220) = 2,004 ÷ 187 = 10.72 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 9.11A, the smallest standard breaker the raw current fits under is 15A. NEC 210.19(A) sizes conductor and OCP at 125% of any continuous load, equivalently 80% of breaker rating. Final selection still depends on the equipment nameplate, whether the load is continuous, conductor ampacity, and local code.

Energy Cost

Running 2,004W costs approximately $0.34 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $2.73 for 8 hours or about $81.76 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 2,004W at 220V is 9.11A. On an AC circuit with a power factor of 0.85, the current rises to 10.72A because reactive current flows alongside the real-power current.

Circuit Type	Formula	Result
DC	2,004 ÷ 220	9.11 A
AC Single Phase (PF 0.85)	2,004 ÷ (220 × 0.85)	10.72 A

Power Factor Reference

Power factor is the main reason 2,004W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 9.11A at 220V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 2,004W pulls 11.39A. That is an extra 2.28A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Fluorescent lamps	0.95	9.59 A
LED lighting	0.9	10.12 A

Computers (without PFC)	0.65	14.01 A

Frequently Asked Questions

How many amps is 2,004W at 220V? expand_more

2,004W at 220V draws 9.11 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 9.11A on DC, 10.72A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

Does voltage affect how many amps 2,004W draws? expand_more

Yes. Higher voltage means lower current for the same real power. 2,004W at 220V draws 9.11A on AC single-phase at PF 1.0 (resistive). As a resistive-baseline comparison at the same wattage, a DC or PF 1.0 load would draw 18.22A at 110V and 4.55A at 440V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.

How much does 2,004W cost to run per hour? expand_more

At the US residential average of $0.17/kWh (last reviewed April 2026), 2,004W costs $0.34 per hour and $2.73 for 8 hours. Rates vary by utility and time of day.

What 220V circuit size does 2,004W need? expand_more

At 9.11A a 10 or 13 A IEC circuit covers this load. In UK installs, a BS 1363 13 A plug fits directly; in Schuko regions a 16 A MCB branch is the typical install. 220V 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).

What is the 80% continuous load rule for 2,004W? 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 9.11A (the current the branch conductors actually carry on AC single-phase at PF 1.0 (resistive)), the minimum breaker that satisfies this is 15A 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.
