About this app
Southwire's voltage drop calculator will help you determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only.

Very useful app! Very easy to explain and show an non-electrically inclined person why they have voltage issues under full load with long wire runs of insufficient gauge. Only suggestion would be, add split phase (dual phase) selections, as most of North America residential and small commercial power is 240v split phase, not just single phase 120v or three phase as is available in the app now.

Good tool, would be great if I could see the entered info instead of dots and dashes. Update - problem is fixed, thanks!

Excellent app for a construction electrician, or maintenance electrician who does rewiring jobs. Multiple options, first you have to learn how to calculate several wires of different sizes in one conduit, but after you do it is intuitive and just a great program
