50 amps to watts by voltage
| Voltage | Watts | kW |
|---|---|---|
| 12 V DC | 600 W | 0.60 kW |
| 24 V DC | 1,200 W | 1.20 kW |
| 120 V | 6,000 W | 6.00 kW |
| 208 V | 10,400 W | 10.40 kW |
| 230 V | 11,500 W | 11.50 kW |
| 240 V | 12,000 W | 12.00 kW |
| 208 V three-phase (PF 0.9) | 16,212 W | 16.21 kW |
| 480 V three-phase (PF 0.9) | 37,411 W | 37.41 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 50 amps?
50 A × 120 V = 6,000 W; at 240 V it is 12,000 W. Watts = amps × volts for resistive single-phase loads.
What breaker do I need for a 50 amp load?
For a continuous load (3+ hours) the NEC sizes the breaker at 125%: 62.5 A → next standard size 70 A. Check local code.
