Frequently Asked Questions

How many amps is 138 kVA at 24V (1-Phase)?

At 24V DC Direct Current, 138 kVA equals 5750.0 Amps at an industrial power factor of 1.0 (or 5750.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 138 kVA at 24V?

For 5750.0A continuous load, NEC requires a 125% rated breaker of 7200A with 11× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 5800A breaker with 11× 400 mm² copper cable.
