Frequently Asked Questions

How many amps is 64 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 64 kVA equals 92.38 Amps at an industrial power factor of 0.85 (or 92.38 Amps at unity power factor 1.0).

What size breaker and wire is needed for 64 kVA at 400V?

For 92.38A continuous load, NEC requires a 125% rated breaker of 125A with 3 AWG copper conductors, while IEC standard sizing uses a 100A breaker with 25 mm² copper cable.
