Frequently Asked Questions

How many amps is 25 kVA at 230V (3-Phase)?

At 230V Three-Phase AC, 25 kVA equals 62.76 Amps at an industrial power factor of 0.85 (or 62.76 Amps at unity power factor 1.0).

What size breaker and wire is needed for 25 kVA at 230V?

For 62.76A continuous load, NEC requires a 125% rated breaker of 80A with 6 AWG copper conductors, while IEC standard sizing uses a 63A breaker with 16 mm² copper cable.
