Grounding in cable trays allows electrical leakage from the outer surfaces of the conductors to be channeled into the tray. It helps to safely direct dangerous currents that may result from electrical faults to the ground. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. There is no restriction as to where the cable tray system is installed. The metal in cable trays may be used as the EGC as per the limitations. Enhanced safety: Grounding provides a safe path for fault currents to flow, significantly reducing the risk of electric shock to personnel and preventing damage to equipment due to overvoltage or insulation failure. It also safeguards against fire hazards caused by excessive heat generated during. that system to lose its UL Classification. If you take what UL states literally, ANY cut to tray (ladder or wi e) would cause a loss of UL Classification. The methods and materials used may vary depending on the structure of the installation. However, the main principle should always be to ensure safe and effective grounding. 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.
