Frequently Asked Questions

How many amps is 38 kW at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 38 kW equals 64.53 Amps at an industrial power factor of 0.85 (or 54.85 Amps at unity power factor 1.0).

What size breaker and wire is needed for 38 kW at 400V?

For 64.53A continuous load, NEC requires a 125% rated breaker of 90A with 6 AWG copper conductors, while IEC standard sizing uses a 70A breaker with 16 mm² copper cable.
