2 amps to watts by voltage
| Voltage | Watts | kW |
|---|---|---|
| 12 V DC | 24 W | 0.02 kW |
| 24 V DC | 48 W | 0.05 kW |
| 120 V | 240 W | 0.24 kW |
| 208 V | 416 W | 0.42 kW |
| 230 V | 460 W | 0.46 kW |
| 240 V | 480 W | 0.48 kW |
| 208 V three-phase (PF 0.9) | 648 W | 0.65 kW |
| 480 V three-phase (PF 0.9) | 1,496 W | 1.50 kW |
Single-phase: W = A × V (power factor 1). Three-phase: W = √3 × A × V × PF; motors and electronics have PF below 1.
FAQ
How many watts is 2 amps?
2 A × 120 V = 240 W; at 240 V it is 480 W. Watts = amps × volts for resistive single-phase loads.
What breaker do I need for a 2 amp load?
For a continuous load (3+ hours) the NEC sizes the breaker at 125%: 2.5 A → next standard size 15 A. Check local code.
