CalcVerter: Wire Size

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
