50 kW Amps at Every Voltage
| Voltage | 1-Phase | 3-Phase |
|---|---|---|
| 120V | 416.67A | 240.57A |
| 208V | 240.38A | 138.79A |
| 240V | 208.33A | 120.28A |
| 277V | 180.51A | 104.22A |
| 480V | 104.17A | 60.14A |
The Formula
Single Phase: Amps = (kW × 1000) ÷ Volts. For 50 kW at 240V: (50 × 1000) ÷ 240 = 208.33A.
Three Phase: Amps = (kW × 1000) ÷ (Volts × 1.732). For 50 kW at 240V 3φ: (50 × 1000) ÷ (240 × 1.732) = 120.28A.
Wire and Breaker for 50 kW
At 240V single-phase (208.3A), recommended: 4/0 AWG copper with a 195A breaker. Use our Wire Size Calculator for exact sizing.
