Voltage Drop Calculator

Southwire’s voltage drop calculator 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.
