2,400 Watts to Amps
2,400 watts is 20 amps at 120 volts and 10 amps at 240 volts (amps = watts ÷ volts, at unity power factor). Every common voltage below.
2,400 Watts to Amps conversion table
| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 200 A | — |
| 24 V DC | 100 A | — |
| 48 V DC | 50 A | — |
| 120 V AC | 20 A | 25 A |
| 208 V AC | 11.5 A | 14.4 A |
| 240 V AC | 10 A | 12.5 A |
| 277 V AC | 8.66 A | 10.8 A |
| 480 V AC | 5 A | 6.25 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 amps (2,400 W ÷ 120 V). On a circuit, a 2,400 W resistive load needs at least a 20 A breaker — and 25% more if it runs 3+ hours continuously.
