25 kW to Amps
25 kW is 104 amps at 240 V single-phase and 30.1 amps at 480 V three-phase (at unity power factor). Single- and three-phase tables below.
25 kW to Amps conversion table
| System | Amps (PF 1.0) | Amps (PF 0.8) |
|---|---|---|
| 120 V single-phase | 208 A | 260 A |
| 240 V single-phase | 104 A | 130 A |
| 208 V three-phase | 69.4 A | 86.7 A |
| 480 V three-phase | 30.1 A | 37.6 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
104 amps single-phase (25 kW = 25,000 W ÷ 240 V). For a continuous 25 kW load — an EV charger, for instance — the circuit must be sized 25% above that.
