2 kW Amps at Every Voltage
| Voltage | 1-Phase | 3-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 = (kW × 1000) ÷ Volts. For 2 kW at 240V: (2 × 1000) ÷ 240 = 8.33A.
Three Phase: Amps = (kW × 1000) ÷ (Volts × 1.732). For 2 kW at 240V 3φ: (2 × 1000) ÷ (240 × 1.732) = 4.81A.
Wire and Breaker for 2 kW
At 240V single-phase (8.3A), recommended: 14 AWG copper with a 15A breaker. Use our Wire Size Calculator for exact sizing.
