Frequently Asked Questions

How many amps is 20 kW at 600V (3-Phase)?

At 600V Three-Phase AC (Canada / Heavy), 20 kW equals 22.64 Amps at an industrial power factor of 0.85 (or 19.25 Amps at unity power factor 1.0).

What size breaker and wire is needed for 20 kW at 600V?

For 22.64A continuous load, NEC requires a 125% rated breaker of 30A with 10 AWG copper conductors, while IEC standard sizing uses a 25A breaker with 2.5 mm² copper cable.
