5,000 Watts to Amps, How Many Amps Is 5,000 Watts?
5,000 Watts equals 41.67 amps at 120V or 20.83 amps at 240V. Common 5000W devices: Large water heater, electric dryer.
5,000 Watts Amps at Every Voltage
| Voltage | Single Phase | Three Phase |
|---|---|---|
| 120V | 41.67A | 24.06A |
| 208V | 24.04A | 13.88A |
| 240V | 20.83A | 12.03A |
| 277V | 18.05A | 10.42A |
| 480V | 10.42A | 6.01A |
The Formula
Single Phase: Amps = Watts ÷ Volts. For 5,000 Watts at 120V: 5000 ÷ 120 = 41.67A.
Three Phase: Amps = Watts ÷ (Volts × 1.732). For 5,000 Watts at 240V 3-phase: 5000 ÷ (240 × 1.732) = 12.03A.
With power factor: Amps = Watts ÷ (Volts × PF). A PF of 0.8 increases the current draw by 25%.
Wire and Breaker for 5,000 Watts at 120V
At 120V, 5,000 Watts draws 41.7A. Recommended: 6 AWG copper wire with a 55A breaker per NEC 310.16. For continuous loads (3+ hours), apply 125% rule. Use our Wire Size Calculator for exact sizing.
