Frequently Asked Questions

How many amps is 7 kVA at 240V (1-Phase)?

At 240V Single-Phase AC (NEC), 7 kVA equals 29.17 Amps at an industrial power factor of 0.85 (or 29.17 Amps at unity power factor 1.0).

What size breaker and wire is needed for 7 kVA at 240V?

For 29.17A continuous load, NEC requires a 125% rated breaker of 40A with 8 AWG copper conductors, while IEC standard sizing uses a 30A breaker with 6 mm² copper cable.
