How Many Amps Is 1,248 Watts at 220V?

1,248 watts at 220V draws 5.67 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 5.67A, 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)

1,248 ÷ 220 = 5.67 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

1,248 ÷ (0.85 × 220) = 1,248 ÷ 187 = 6.67 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 5.67A, 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 1,248W costs approximately $0.21 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $1.70 for 8 hours or about $50.92 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 1,248W at 220V is 5.67A. On an AC circuit with a power factor of 0.85, the current rises to 6.67A because reactive current flows alongside the real-power current.

Circuit Type	Formula	Result
DC	1,248 ÷ 220	5.67 A
AC Single Phase (PF 0.85)	1,248 ÷ (220 × 0.85)	6.67 A

Power Factor Reference

Power factor is the main reason 1,248W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 5.67A at 220V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 1,248W pulls 7.09A. That is an extra 1.42A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Resistive (heaters, incandescent)	1	5.67 A
Fluorescent lamps	0.95	5.97 A
LED lighting	0.9	6.3 A
Synchronous motors	0.9	6.3 A
Typical mixed loads	0.85	6.67 A
Induction motors (full load)	0.8	7.09 A
Computers (without PFC)	0.65	8.73 A
Induction motors (no load)	0.35	16.21 A

Frequently Asked Questions

How many amps is 1,248W at 220V? expand_more

1,248W at 220V draws 5.67 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 5.67A on DC, 6.67A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

What 220V circuit size does 1,248W need? expand_more

At 5.67A a 10 A IEC circuit covers this load with headroom. UK installations commonly use a BS 1363 13 A fused plug instead, which is rated by the plug's internal fuse rather than the branch breaker. 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).

Does voltage affect how many amps 1,248W draws? expand_more

Yes. Higher voltage means lower current for the same real power. 1,248W at 220V draws 5.67A 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 11.35A at 110V and 2.84A at 440V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.

What kind of outlet does a 1,248W appliance need on 220V? expand_more

220V 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 1,248W on 220V the current is 5.67A, which fits a standard residential socket in any of these regions (well inside the 13-16 A typical branch). Verify against the appliance's spec sheet, the local wiring regulations, and the actual installed receptacle type.

How much does 1,248W cost to run per hour? expand_more

At the US residential average of $0.17/kWh (last reviewed April 2026), 1,248W costs $0.21 per hour and $1.70 for 8 hours. Rates vary by utility and time of day.
