How Many Amps Is 3,480 Watts at 230V?

At 230V, 3,480 watts converts to 15.13 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 15.13A, the NEC 210.19(A) continuous-load sizing math (125% of the load, equivalently 80% of the breaker rating) points to a 20A breaker as the smallest standard size that covers this load continuously.

15.13

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)

3,480 ÷ 230 = 15.13 A

AC Single Phase (PF = 0.85)

I(A) = P(W) ÷ (PF × V(V))

3,480 ÷ (0.85 × 230) = 3,480 ÷ 195.5 = 17.8 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 15.13A, the smallest standard breaker the raw current fits under is 20A. 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 3,480W costs approximately $0.59 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $4.73 for 8 hours or about $141.98 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 3,480W at 230V is 15.13A. On an AC circuit with a power factor of 0.85, the current rises to 17.8A because reactive current flows alongside the real-power current.

Power Factor Reference

Power factor is the main reason 3,480W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 15.13A at 230V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 3,480W pulls 18.91A. That is an extra 3.78A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Frequently Asked Questions

3,480W at 230V draws 15.13 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 15.13A on DC, 17.8A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.
Yes. Higher voltage means lower current for the same real power. 3,480W at 230V draws 15.13A 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 30.26A at 115V and 7.57A at 460V. Doubling the voltage halves the current and also halves the I²R losses in the conductors.
At 15.13A a 16 A IEC branch covers this load within the residential standard. Large continuous loads (ovens, instant water heaters) usually move to a dedicated 20 or 32 A circuit. 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).
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 3,480W on 230V the current is 15.13A, which fits a standard residential socket in any of these regions (near the 16 A Schuko / continental branch limit). Verify against the appliance's spec sheet, the local wiring regulations, and the actual installed receptacle type.
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.
