  • Can copper core wires be used in cable trays

    Can copper core wires be used 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). Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. The intent of this article is to review grounding practices for cable tray. The most frequently used tray cables are: Type TC – Tray Cable – (NEC Article 336) –Power and control tray cable type TC is a factory assembly of two or more insulated conductors, with or without associated bare or covered grounding conductors, under a non-metallic jacket. This is a description of how to select, install, and support these metal or plastic frames, on which electrical wires are installed.
