Frequently Asked Questions

How many amps is 3 kVA at 230V (1-Phase)?

At 230V Single-Phase AC (IEC), 3 kVA equals 13.04 Amps at an industrial power factor of 0.85 (or 13.04 Amps at unity power factor 1.0).

What size breaker and wire is needed for 3 kVA at 230V?

For 13.04A continuous load, NEC requires a 125% rated breaker of 20A with 12 AWG copper conductors, while IEC standard sizing uses a 15A breaker with 2.5 mm² copper cable.
