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. The flexibility and scalability of cable trays make them an ideal choice for environments where cable density and organization can. Grounding in cable trays is an important practice to increase electrical safety and prevent hazards in case of faults. However, the main principle should always be to ensure safe and effective grounding. In large installations, trays are connected in multiple sections, and bonding prevents voltage differences that could cause arcing or system failures. -
