Frequently Asked Questions

How many amps is 18.5 kVA at 600V (3-Phase)?

At 600V Three-Phase AC (Canada / Heavy), 18.5 kVA equals 17.8 Amps at an industrial power factor of 0.85 (or 17.8 Amps at unity power factor 1.0).

What size breaker and wire is needed for 18.5 kVA at 600V?

For 17.8A continuous load, NEC requires a 125% rated breaker of 25A with 12 AWG copper conductors, while IEC standard sizing uses a 20A breaker with 2.5 mm² copper cable.
