Grounding of cable trays and conduits

This section explains how, in PCS (Precast Conduit System) engineering, techniques such as bridging, multi-point grounding, and end-joining are used to achieve continuous grounding of metal cable trays and conduits, thereby enhancing their auxiliary shielding function. 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. 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) BEFO...
