Frequently Asked Questions

How many amps is 270 kW at 230V (3-Phase)?

At 230V Three-Phase AC, 270 kW equals 797.36 Amps at an industrial power factor of 0.85 (or 677.76 Amps at unity power factor 1.0).

What size breaker and wire is needed for 270 kW at 230V?

For 797.36A continuous load, NEC requires a 125% rated breaker of 1000A with 2× 1000 kcmil (Parallel) copper conductors, while IEC standard sizing uses a 800A breaker with 2× 400 mm² copper cable.
