Frequently Asked Questions

How many amps is 124 kVA at 208V (1-Phase)?

At 208V Single-Phase AC, 124 kVA equals 596.15 Amps at an industrial power factor of 0.85 (or 596.15 Amps at unity power factor 1.0).

What size breaker and wire is needed for 124 kVA at 208V?

For 596.15A continuous load, NEC requires a 125% rated breaker of 800A with 2× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 600A breaker with 2× 400 mm² copper cable.
