100 kW Amps at Every Voltage
| Voltage | 1-Phase | 3-Phase |
|---|---|---|
| 120V | 833.33A | 481.14A |
| 208V | 480.77A | 277.58A |
| 240V | 416.67A | 240.57A |
| 277V | 361.01A | 208.44A |
| 480V | 208.33A | 120.28A |
The Formula
Single Phase: Amps = (kW × 1000) ÷ Volts. For 100 kW at 240V: (100 × 1000) ÷ 240 = 416.67A.
Three Phase: Amps = (kW × 1000) ÷ (Volts × 1.732). For 100 kW at 240V 3φ: (100 × 1000) ÷ (240 × 1.732) = 240.57A.
Wire and Breaker for 100 kW
At 240V single-phase (416.7A), recommended: 4/0 AWG copper with a 195A breaker. Use our Wire Size Calculator for exact sizing.
