at 240V single phase
6 kW Amps at Every Voltage
| Voltage | 1-Phase | 3-Phase |
|---|---|---|
| 120V | 50.00A | 28.87A |
| 208V | 28.85A | 16.65A |
| 240V | 25.00A | 14.43A |
| 277V | 21.66A | 12.51A |
| 480V | 12.50A | 7.22A |
The Formula
Single Phase: Amps = (kW × 1000) ÷ Volts. For 6 kW at 240V: (6 × 1000) ÷ 240 = 25.00A.
Three Phase: Amps = (kW × 1000) ÷ (Volts × 1.732). For 6 kW at 240V 3φ: (6 × 1000) ÷ (240 × 1.732) = 14.43A.
Wire and Breaker for 6 kW
At 240V single-phase (25.0A), recommended: 10 AWG copper with a 30A breaker. Use our Wire Size Calculator for exact sizing.
