Formula estimate only. Generator manufacturer data, transient response, and motor starting are separate checks.

Reference table

Estimate generator apparent power and three-phase 600 V current from kW and power factor.

Formula basis: kVA = kW / power factor; three-phase amps = kVA x 1000 / (sqrt(3) x volts).
