15 kW to Amps
15 kW is 62.5 amps at 240 V single-phase and 18 amps at 480 V three-phase (at unity power factor). Single- and three-phase tables below.
15 kW to Amps conversion table
| System | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 120 V single-phase | 125 A | 156 A |
| 240 V single-phase | 62.5 A | 78.1 A |
| 208 V three-phase | 41.6 A | 52 A |
| 480 V three-phase | 18 A | 22.6 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
62.5 amps single-phase (15 kW = 15,000 W ÷ 240 V). For a continuous 15 kW load — an EV charger, for instance — the circuit must be sized 25% above that.
