Calculation basis
Three-phase kW = √3 × voltage × amps × power factor ÷ 1,000.
Planned rows
Enter current and voltage readings for every phase shown to calculate estimated kW and actual load % automatically at PF 1.0. A direct kW reading overrides the estimate.

* calc. = calculated from recorded voltage and current at PF 1.0. Direct measured kW is shown without a suffix.
Calculation basis
This tool calculates expected current for a unity-power-factor resistive load bank. A generator’s nameplate current may be based on its kVA rating at a lower power factor, so full rated kW on a resistive bank may not equal nameplate full-load amps.
Use these values for planning—not as conductor sizing, connection approval, or proof of a required test procedure.
