Frequently Asked Questions

How many amps is 42 kVA at 24V (1-Phase)?

At 24V DC Direct Current, 42 kVA equals 1750.0 Amps at an industrial power factor of 1.0 (or 1750.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 42 kVA at 24V?

For 1750.0A continuous load, NEC requires a 125% rated breaker of 2500A with 4× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 2000A breaker with 4× 400 mm² copper cable.
