Steel and aluminum cable tray systems are excellent equipment grounding conductors if they are properly designed, specified, installed, and inspected. 60(A)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 metal in cable trays may be used as the EGC as per the limitations. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control cables, Ethernet, and fiber optic lines. If cable is installed. that system to lose its UL Classification. For example, when a straight section of tray is cut to length and used in conjunction with a factory fitting — this installation would also. Cable tray grounding is an indispensable aspect of electrical installations that plays a pivotal role in ensuring safety, reliability, and efficiency. It involves connecting cable trays to the facility's grounding system, providing a low-impedance path for fault currents and protecting personnel. If a carbon steel cable tray/zinc plated (either in ceiling or wall mounted) that carries only non-power conductors (ethernet, HDMI, audio etc. Permits this? You are permitted to do.
