Frequently Asked Questions

How many amps is 25 kW at 600V (3-Phase)?

At 600V Three-Phase AC (Canada / Heavy), 25 kW equals 28.3 Amps at an industrial power factor of 0.85 (or 24.06 Amps at unity power factor 1.0).

What size breaker and wire is needed for 25 kW at 600V?

For 28.3A continuous load, NEC requires a 125% rated breaker of 40A with 10 AWG copper conductors, while IEC standard sizing uses a 30A breaker with 4 mm² copper cable.
