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). When should you use an exposed-run (ER) tray-rated cable? Unlike standard tray-rated cables, exposed-run tray-rated cables can be installed in applications where the cable will drop from. Tray cables (TC) are multi-conductor cables designed and rated for installation in cable trays and raceways or supported by messenger wires.
