2,500 Watts to Amps
2,500 watts is 20.8 amps at 120 volts and 10.4 amps at 240 volts (amps = watts ÷ volts, at unity power factor). Every common voltage below.
2,500 Watts to Amps conversion table
| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 208 A | — |
| 24 V DC | 104 A | — |
| 48 V DC | 52.1 A | — |
| 120 V AC | 20.8 A | 26 A |
| 208 V AC | 12 A | 15 A |
| 240 V AC | 10.4 A | 13 A |
| 277 V AC | 9.03 A | 11.3 A |
| 480 V AC | 5.21 A | 6.51 A |
PF = power factor. Resistive loads (heaters, incandescent lights) are PF 1.0; motors and compressors typically run PF 0.8-0.9. For a different value, use the interactive converter.
Frequently asked questions
20.8 amps (2,500 W ÷ 120 V). On a circuit, a 2,500 W resistive load needs at least a 25 A breaker — and 25% more if it runs 3+ hours continuously.
