Home / Do cable trays need to be reinforced with partitions
Due to their exposure to the open air because of the cable trays, the wires contained within need a very durable outer covering. The regulations dictate that the cables must either be Type TC (also known as Tray Rated) or must be metal-armored (Type MC). This is a description of how to select, install, and support these metal or plastic frames, on which electrical wires are installed. What is the role of a cable tray in electrical engineering? A cable tray allows for the neat and aesthetic arrangement of cables, improves the reliability. The following pages address the 2014 National Electrical Code® requirements for cable tray systems as well as design solutions from practical experience.
