30 Amps to Watts
30 amps is 3,600 watts at 120 volts and 7,200 watts at 240 volts (watts = amps × volts, at unity power factor).
30 Amps to Watts conversion table
| Voltage | Watts (PF 1.0) | Watts (PF 0.8) |
|---|---|---|
| 12 V DC | 360 W | — |
| 24 V DC | 720 W | — |
| 48 V DC | 1,440 W | — |
| 120 V AC | 3,600 W | 2,880 W |
| 208 V AC | 6,240 W | 4,992 W |
| 240 V AC | 7,200 W | 5,760 W |
| 277 V AC | 8,310 W | 6,648 W |
| 480 V AC | 14,400 W | 11,520 W |
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
3,600 watts (30 A × 120 V) for DC or resistive AC loads. With a 0.8 power factor (motors), the same current only delivers 2,880 W of real power.
