Frequently Asked Questions

How many amps is 15 kVA at 600V (3-Phase)?

At 600V Three-Phase AC (Canada / Heavy), 15 kVA equals 14.43 Amps at an industrial power factor of 0.85 (or 14.43 Amps at unity power factor 1.0).

What size breaker and wire is needed for 15 kVA at 600V?

For 14.43A continuous load, NEC requires a 125% rated breaker of 20A with 14 AWG copper conductors, while IEC standard sizing uses a 15A breaker with 1.5 mm² copper cable.
