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. Wire mesh cable trays are widely used in commercial offices, industrial facilities, data centers, and smart building infrastructure because they provide unmatched flexibility, excellent airflow, and fast, adaptable installation. This deeper guide walks through the logic, adds practical checks, and flags a. It is essential that the grounding of cable tray systems, including the cables in the tray systems, is inspected for compliance with the grounding requirements in the National Electrical Code (NEC) BEFORE the cabling in the tray is energized and BEFORE cable is installed. Consider it as an emergency electricity exit. When a wire is broken or is leaking power, the EGC captures this energy.
