6.25 A
at 240V single phase
1.5 kW Amps at Every Voltage
| Voltage | 1-Phase | 3-Phase |
|---|---|---|
| 120V | 12.50A | 7.22A |
| 208V | 7.21A | 4.16A |
| 240V | 6.25A | 3.61A |
| 277V | 5.42A | 3.13A |
| 480V | 3.13A | 1.80A |
The Formula
Single Phase: Amps = (kW × 1000) ÷ Volts. For 1.5 kW at 240V: (1.5 × 1000) ÷ 240 = 6.25A.
Three Phase: Amps = (kW × 1000) ÷ (Volts × 1.732). For 1.5 kW at 240V 3φ: (1.5 × 1000) ÷ (240 × 1.732) = 3.61A.
Wire and Breaker for 1.5 kW
At 240V single-phase (6.3A), recommended: 14 AWG copper with a 15A breaker. Use our Wire Size Calculator for exact sizing.
