Frequently Asked Questions

How many amps is 50 kVA at 230V (3-Phase)?

At 230V Three-Phase AC, 50 kVA equals 125.51 Amps at an industrial power factor of 0.85 (or 125.51 Amps at unity power factor 1.0).

What size breaker and wire is needed for 50 kVA at 230V?

For 125.51A continuous load, NEC requires a 125% rated breaker of 160A with 1 AWG copper conductors, while IEC standard sizing uses a 150A breaker with 50 mm² copper cable.
