Voltage drop & gauge API

Computes conductor voltage drop (volts and %) for single- or three-phase runs by AWG, length, current and material, and recommends the thinnest gauge meeting a max-drop limit. Answers 'What is the voltage drop on this wire run?', 'Is AWG 12 adequate or do I need a thicker gauge?'.
