Home / Is it permissible to lay wires in cable trays
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. en completely installed, without damage either to conductors orstructural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
Despite their versatility, cable trays are not suitable for every situation. They are strictly prohibited in hoistways or any location where they could face severe physical damage. Cable trays
