Frequently Asked Questions

How many amps is 52 kVA at 400V (3-Phase)?

At 400V Three-Phase AC (IEC Europe), 52 kVA equals 75.06 Amps at an industrial power factor of 0.85 (or 75.06 Amps at unity power factor 1.0).

What size breaker and wire is needed for 52 kVA at 400V?

For 75.06A continuous load, NEC requires a 125% rated breaker of 100A with 4 AWG copper conductors, while IEC standard sizing uses a 80A breaker with 16 mm² copper cable.
