About VFD Cables

A variable-frequency drive (VFD) cable is a special cable construction for the inverter-to-motor cable that has some or all of the following attributes.

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. How to calculate voltage drop, you ask?

VFD Sizing Calculator

Use this simple tool to input relevant information for your installation of cable from VFD (variable-frequency drive) to Motor and it will select the proper size of cable for your installation.
