Frequently Asked Questions
How many amps is 78 kW at 24V (1-Phase)?
At 24V DC Direct Current, 78 kW equals 3250.0 Amps at an industrial power factor of 1.0 (or 3250.0 Amps at unity power factor 1.0).
What size breaker and wire is needed for 78 kW at 24V?
For 3250.0A continuous load, NEC requires a 125% rated breaker of 4100A with 6× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 3300A breaker with 6× 400 mm² copper cable.
