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.
- Extended results are modified to have more specific information
- Pop up has been added to get attention of the user whenever there is a warning on conductor sizes
Ratings and Reviews
The last version was better
The versions before this was a lot easier to use and navigate.
Very good app, well written and designed. Best voltage drop I've seen.
