How Many Amps Is 2,300 Watts at 240V?

At 240V, 2,300 watts converts to 9.58 amps using the AC single-phase formula (Amps = Watts ÷ (V × PF)) at PF 1.0 for a resistive load. AC resistive at PF 1.0 and the DC baseline land on the same number at this voltage.

At 9.58A, 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. At 240V, the lower current draw allows smaller wire and breakers compared to 120V.

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)

2,300 ÷ 240 = 9.58 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

2,300 ÷ (0.85 × 240) = 2,300 ÷ 204 = 11.27 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 9.58A, 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 2,300W costs approximately $0.39 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $3.13 for 8 hours or about $93.84 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 2,300W at 240V is 9.58A. On an AC circuit with a power factor of 0.85, the current rises to 11.27A because reactive current flows alongside the real-power current.

Circuit Type	Formula	Result
DC	2,300 ÷ 240	9.58 A
AC Single Phase (PF 0.85)	2,300 ÷ (240 × 0.85)	11.27 A

Power Factor Reference

Power factor is the main reason 2,300W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 9.58A at 240V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 2,300W pulls 11.98A. That is an extra 2.4A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Resistive (heaters, incandescent)	1	9.58 A
Fluorescent lamps	0.95	10.09 A
LED lighting	0.9	10.65 A
Synchronous motors	0.9	10.65 A

Induction motors (full load)	0.8	11.98 A
Computers (without PFC)	0.65	14.74 A

Frequently Asked Questions

How many amps is 2,300W at 240V? expand_more

2,300W at 240V draws 9.58 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 9.58A on DC, 11.27A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

Does voltage affect how many amps 2,300W draws? expand_more

Yes. Higher voltage means lower current for the same real power. 2,300W at 240V draws 9.58A 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 19.17A at 120V and 4.79A at 480V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.

What kind of 240V outlet does a 2,300W appliance need? expand_more

At US 240V a "regular outlet" is not a standard 120V NEMA 5-15R household receptacle, it's a dedicated 240V branch-circuit receptacle sized to the load. At 2,300W on 240V the current is 9.58A, which typically maps to a NEMA 6-15 receptacle on a 240V/15A circuit. Receptacle choice also depends on whether a neutral is needed, the equipment's cord and plug configuration, and any local amendments. Verify against the appliance's spec sheet and the receiving circuit.

What is the 80% continuous load rule for 2,300W? 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 9.58A (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.

What power factor should I use for 2,300W calculations? expand_more

For resistive loads (heaters, incandescent bulbs, electric kettles) use PF 1.0. For motors, use 0.80. For mixed office/residential use 0.85. For computers and LED arrays the effective PF can be 0.65 or lower. Power factor only applies to AC.
