80 amps to watts by voltage
| Voltage | Watts | kW |
|---|---|---|
| 12 V DC | 960 W | 0.96 kW |
| 24 V DC | 1,920 W | 1.92 kW |
| 120 V | 9,600 W | 9.60 kW |
| 208 V | 16,640 W | 16.64 kW |
| 230 V | 18,400 W | 18.40 kW |
| 240 V | 19,200 W | 19.20 kW |
| 208 V three-phase (PF 0.9) | 25,938 W | 25.94 kW |
| 480 V three-phase (PF 0.9) | 59,858 W | 59.86 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 80 amps?
80 A × 120 V = 9,600 W; at 240 V it is 19,200 W. Watts = amps × volts for resistive single-phase loads.
What breaker do I need for a 80 amp load?
For a continuous load (3+ hours) the NEC sizes the breaker at 125%: 100 A → next standard size 100 A. Check local code.
