Frequently Asked Questions

How many amps is 150 kVA at 415V (3-Phase)?

At 415V Three-Phase AC (UK / AU), 150 kVA equals 208.68 Amps at an industrial power factor of 0.85 (or 208.68 Amps at unity power factor 1.0).

What size breaker and wire is needed for 150 kVA at 415V?

For 208.68A continuous load, NEC requires a 125% rated breaker of 300A with 4/0 AWG copper conductors, while IEC standard sizing uses a 225A breaker with 95 mm² copper cable.
