Frequently Asked Questions

How many amps is 72 kVA at 600V (3-Phase)?

At 600V Three-Phase AC (Canada / Heavy), 72 kVA equals 69.28 Amps at an industrial power factor of 0.85 (or 69.28 Amps at unity power factor 1.0).

What size breaker and wire is needed for 72 kVA at 600V?

For 69.28A continuous load, NEC requires a 125% rated breaker of 90A with 4 AWG copper conductors, while IEC standard sizing uses a 70A breaker with 16 mm² copper cable.
