15,000 Watts to Amps
15,000 watts is 125 amps at 120 volts and 62.5 amps at 240 volts (amps = watts ÷ volts, at unity power factor). Every common voltage below.
15,000 Watts to Amps conversion table
| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 1,250 A | — |
| 24 V DC | 625 A | — |
| 48 V DC | 313 A | — |
| 120 V AC | 125 A | 156 A |
| 208 V AC | 72.1 A | 90.1 A |
| 240 V AC | 62.5 A | 78.1 A |
| 277 V AC | 54.2 A | 67.7 A |
| 480 V AC | 31.3 A | 39.1 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
125 amps (15,000 W ÷ 120 V). On a circuit, a 15,000 W resistive load needs at least a 125 A breaker — and 25% more if it runs 3+ hours continuously.
