2,000 Watts to Amps — How Many Amps Is 2,000 Watts?
2,000 Watts equals 16.67 amps at 120V or 8.33 amps at 240V. Common 2000W devices: Large space heater, small power tool.
2,000 Watts Amps at Every Voltage
| Voltage | Single Phase | Three Phase |
|---|---|---|
| 120V | 16.67A | 9.62A |
| 208V | 9.62A | 5.55A |
| 240V | 8.33A | 4.81A |
| 277V | 7.22A | 4.17A |
| 480V | 4.17A | 2.41A |
The Formula
Single Phase: Amps = Watts ÷ Volts. For 2,000 Watts at 120V: 2000 ÷ 120 = 16.67A.
Three Phase: Amps = Watts ÷ (Volts × 1.732). For 2,000 Watts at 240V 3-phase: 2000 ÷ (240 × 1.732) = 4.81A.
With power factor: Amps = Watts ÷ (Volts × PF). A PF of 0.8 increases the current draw by 25%.
Wire and Breaker for 2,000 Watts at 120V
At 120V, 2,000 Watts draws 16.7A. Recommended: 12 AWG copper wire with a 20A breaker per NEC 310.16. For continuous loads (3+ hours), apply 125% rule. Use our Wire Size Calculator for exact sizing.
