10,000 Watts to Amps, How Many Amps Is 10,000 Watts?
10,000 Watts equals 83.33 amps at 120V or 41.67 amps at 240V. Common 10000W devices: Electric range, EV charger (48A), large welder.
10,000 Watts Amps at Every Voltage
| Voltage | Single Phase | Three Phase |
|---|---|---|
| 120V | 83.33A | 48.11A |
| 208V | 48.08A | 27.76A |
| 240V | 41.67A | 24.06A |
| 277V | 36.10A | 20.84A |
| 480V | 20.83A | 12.03A |
The Formula
Single Phase: Amps = Watts ÷ Volts. For 10,000 Watts at 120V: 10000 ÷ 120 = 83.33A.
Three Phase: Amps = Watts ÷ (Volts × 1.732). For 10,000 Watts at 240V 3-phase: 10000 ÷ (240 × 1.732) = 24.06A.
With power factor: Amps = Watts ÷ (Volts × PF). A PF of 0.8 increases the current draw by 25%.
Wire and Breaker for 10,000 Watts at 120V
At 120V, 10,000 Watts draws 83.3A. Recommended: 4 AWG copper wire with a 70A breaker per NEC 310.16. For continuous loads (3+ hours), apply 125% rule. Use our Wire Size Calculator for exact sizing.
