| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 66.7 A | — |
| 24 V DC | 33.3 A | — |
| 48 V DC | 16.7 A | — |
| 120 V AC | 6.67 A | 8.33 A |
| 208 V AC | 3.85 A | 4.81 A |
| 240 V AC | 3.33 A | 4.17 A |
| 277 V AC | 2.89 A | 3.61 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.
What draws about 800 watts?
Frequently asked questions
6.67 amps (800 W ÷ 120 V). On a circuit, a 800 W resistive load needs at least a 15 A breaker — and 25% more if it runs 3+ hours continuously.
