Frequently Asked Questions

How many amps is 750 kVA at 120V (1-Phase)?

At 120V Single-Phase AC, 750 kVA equals 6250.0 Amps at an industrial power factor of 0.85 (or 6250.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 750 kVA at 120V?

For 6250.0A continuous load, NEC requires a 125% rated breaker of 7900A with 12× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 6300A breaker with 11× 400 mm² copper cable.
