12,000 Watts to Amps
12,000 watts is 100 amps at 120 volts and 50 amps at 240 volts (amps = watts ÷ volts, at unity power factor). Every common voltage below.
12,000 Watts to Amps conversion table
| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 1,000 A | — |
| 24 V DC | 500 A | — |
| 48 V DC | 250 A | — |
| 120 V AC | 100 A | 125 A |
| 208 V AC | 57.7 A | 72.1 A |
| 240 V AC | 50 A | 62.5 A |
| 277 V AC | 43.3 A | 54.2 A |
| 480 V AC | 25 A | 31.3 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
100 amps (12,000 W ÷ 120 V). On a circuit, a 12,000 W resistive load needs at least a 100 A breaker — and 25% more if it runs 3+ hours continuously.
