Calculation

For single-phase circuits:
Wire Circular mm2= (Conductor Resistivity)(2)(Amps)(One Way Distance in inch) /  Allowable Voltage Drop

For 3-phase circuits:
Wire Circular mm2= (Conductor Resistivity)(2)(Amps)(One Way Distance in inch)(.866) / Allowable Voltage Drop

This is at a temp of 20°C!
