  • Continuous grounding of cable trays

    Continuous grounding of cable trays

    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 wiring systems have excellent safety and dependability records. These excellent records are the result of cable tray's unique features plus the proper design and installation of the cable tray wiring systems. 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. This provides a safe path for any stray electrical currents to flow safely into the earth, avoiding damage to your equipment and reducing the risk of electric shocks.
