Frequently Asked Questions

How many amps is 204 kVA at 120V (1-Phase)?

At 120V Single-Phase AC, 204 kVA equals 1700.0 Amps at an industrial power factor of 0.85 (or 1700.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 204 kVA at 120V?

For 1700.0A continuous load, NEC requires a 125% rated breaker of 2500A with 4× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 2000A breaker with 3× 400 mm² copper cable.
