Frequently Asked Questions

How many amps is 186 kVA at 240V (1-Phase)?

At 240V Single-Phase AC (NEC), 186 kVA equals 775.0 Amps at an industrial power factor of 0.85 (or 775.0 Amps at unity power factor 1.0).

What size breaker and wire is needed for 186 kVA at 240V?

For 775.0A 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.
