1,200 Watts to Amps
1,200 watts is 10 amps at 120 volts and 5 amps at 240 volts (amps = watts ÷ volts, at unity power factor). Every common voltage below.
1,200 Watts to Amps conversion table
| Voltage | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 12 V DC | 100 A | — |
| 24 V DC | 50 A | — |
| 48 V DC | 25 A | — |
| 120 V AC | 10 A | 12.5 A |
| 208 V AC | 5.77 A | 7.21 A |
| 240 V AC | 5 A | 6.25 A |
| 277 V AC | 4.33 A | 5.42 A |
| 480 V AC | 2.5 A | 3.13 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 1,200 watts?
Frequently asked questions
10 amps (1,200 W ÷ 120 V). On a circuit, a 1,200 W resistive load needs at least a 15 A breaker — and 25% more if it runs 3+ hours continuously.
