Wire Size Calculator

The wire size calculator will give you a simple solution for to choose size of wires and cables for pump applications in golf courses, landscape projects, and agriculture.

Formula:

For single-phase circuits:


  • Wire Circular Mils = (Conductor Resistivity)(2)(Amps)(One Way Distance in Feet) /
                                             Allowable Voltage Drop


For 3-phase circuits:

  • Wire Circular Mils = (Conductor Resistivity)(2)(Amps)(One Way Distance in Feet)(.866) /
                                            Allowable Voltage Drop
