How Many Amps Is 1,375 Watts at 230V?

1,375 watts equals 5.98 amps at 230V on an AC single-phase resistive circuit (PF 1.0). AC resistive at PF 1.0 and the DC baseline land on the same number at this voltage.

At 5.98A, 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)

1,375 ÷ 230 = 5.98 A

AC Single Phase (PF = 0.85)

I(A) = P(W) ÷ (PF × V(V))

1,375 ÷ (0.85 × 230) = 1,375 ÷ 195.5 = 7.03 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 5.98A, 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 1,375W costs approximately $0.23 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $1.87 for 8 hours or about $56.10 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 1,375W at 230V is 5.98A. On an AC circuit with a power factor of 0.85, the current rises to 7.03A because reactive current flows alongside the real-power current.

Power Factor Reference

Power factor is the main reason 1,375W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 5.98A at 230V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 1,375W pulls 7.47A. That is an extra 1.49A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Frequently Asked Questions

1,375W at 230V draws 5.98 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 5.98A on DC, 7.03A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.
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.
Yes. Higher voltage means lower current for the same real power. 1,375W at 230V draws 5.98A 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 11.96A at 115V and 2.99A at 460V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.
At the US residential average of $0.17/kWh (last reviewed April 2026), 1,375W costs $0.23 per hour and $1.87 for 8 hours. Rates vary by utility and time of day.
AC circuits with reactive loads have a power factor below 1.0, so they draw extra current. At PF 0.85, 1,375W at 230V draws 7.03A instead of 5.98A (DC). That is about 18% more current for the same real power.
