Frequently Asked Questions

How many amps is 1.5 kW at 240V (1-Phase)?

At 240V Single-Phase AC (NEC), 1.5 kW equals 7.35 Amps at an industrial power factor of 0.85 (or 6.25 Amps at unity power factor 1.0).

What size breaker and wire is needed for 1.5 kW at 240V?

For 7.35A continuous load, NEC requires a 125% rated breaker of 10A with 14 AWG copper conductors, while IEC standard sizing uses a 10A breaker with 1.5 mm² copper cable.
