In addition to conduit and seal-tite raceway, it is acceptable to use cable that is
rated Tray Cable Exposed Runs (TC-ER), for power and control wiring on
drive installations. The National Electrical Code (NEC) and NFPA 79 outline

electrical standard for industrial machinery states that, cable tray use and
installation, the utilization of equipment or devices, equipment grounding,
and conductor size must be implemented according to NFPA 79, NEC article
