Frequently Asked Questions

How many amps is 108 kVA at 120V (1-Phase)?

At 120V Single-Phase AC, 108 kVA equals 900.0 Amps at an industrial power factor of 0.85 (or 900.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 108 kVA at 120V?

For 900.0A continuous load, NEC requires a 125% rated breaker of 1200A with 2× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 1000A breaker with 2× 400 mm² copper cable.
