Frequently Asked Questions

How many amps is 30 kW at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 30 kW equals 50.94 Amps at an industrial power factor of 0.85 (or 43.3 Amps at unity power factor 1.0).

What size breaker and wire is needed for 30 kW at 400V?

For 50.94A continuous load, NEC requires a 125% rated breaker of 70A with 6 AWG copper conductors, while IEC standard sizing uses a 60A breaker with 10 mm² copper cable.
