Frequently Asked Questions

How many amps is 580 kVA at 415V (3-Phase)?

At 415V Three-Phase AC (UK / AU), 580 kVA equals 806.9 Amps at an industrial power factor of 0.85 (or 806.9 Amps at unity power factor 1.0).

What size breaker and wire is needed for 580 kVA at 415V?

For 806.9A 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.
