VFD Cable Selection: Understand the Changes to NFPA 79
Machine designers who want to take advantage of the precision and energy efficiency offered by variable frequency drives (VFDs) need to make sure the cable that connects the drive to the motor performs reliably. Choosing a poorly constructed VFD cable can hinder a machine’s performance, or the cable may break down and compromise safety.
