5 amps to watts by voltage
| Voltage | Watts | kW |
|---|---|---|
| 12 V DC | 60 W | 0.06 kW |
| 24 V DC | 120 W | 0.12 kW |
| 120 V | 600 W | 0.60 kW |
| 208 V | 1,040 W | 1.04 kW |
| 230 V | 1,150 W | 1.15 kW |
| 240 V | 1,200 W | 1.20 kW |
| 208 V three-phase (PF 0.9) | 1,621 W | 1.62 kW |
| 480 V three-phase (PF 0.9) | 3,741 W | 3.74 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 5 amps?
5 A × 120 V = 600 W; at 240 V it is 1,200 W. Watts = amps × volts for resistive single-phase loads.
What breaker do I need for a 5 amp load?
For a continuous load (3+ hours) the NEC sizes the breaker at 125%: 6.25 A → next standard size 15 A. Check local code.
