100 kW to Amps
100 kW is 417 amps at 240 V single-phase and 120 amps at 480 V three-phase (at unity power factor). Single- and three-phase tables below.
100 kW to Amps conversion table
| System | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 120 V single-phase | 833 A | 1,042 A |
| 240 V single-phase | 417 A | 521 A |
| 208 V three-phase | 278 A | 347 A |
| 480 V three-phase | 120 A | 150 A |
PF = power factor. Resistive loads (heaters, incandescent lights) are PF 1.0; motors and compressors typically run PF 0.8-0.9. For a different value, use the interactive converter.
Frequently asked questions
417 amps single-phase (100 kW = 100,000 W ÷ 240 V). For a continuous 100 kW load — an EV charger, for instance — the circuit must be sized 25% above that.
