Frequently Asked Questions

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

At 400V Three-Phase AC (IEC Europe), 22 kW equals 37.36 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 kW at 400V?

For 37.36A continuous load, NEC requires a 125% rated breaker of 50A with 8 AWG copper conductors, while IEC standard sizing uses a 40A breaker with 6 mm² copper cable.
