How to use the kW to Amps NZ calculator
Convert kilowatts to amps for New Zealand single-phase systems with a calculator configured for the nominal 230V mains supply.
The calculator starts with a 230V single-phase AC preset and a power factor of 1. Enter either current or power, adjust the electrical settings to match the equipment nameplate, and the result updates immediately.
Formula used
For this single-phase AC conversion, the calculator uses (kW × 1000) ÷ (Volts × PF). Use the actual supply voltage and the equipment's rated power factor whenever accuracy matters.
