Frequently Asked Questions

How many amps is 22 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 22 kVA equals 31.75 Amps at an industrial power factor of 0.85 (or 31.75 Amps at unity power factor 1.0).

What size breaker and wire is needed for 22 kVA at 400V?

For 31.75A continuous load, NEC requires a 125% rated breaker of 40A with 8 AWG copper conductors, while IEC standard sizing uses a 32A breaker with 4 mm² copper cable.
