Cable tray grounding wire 30 meters

≤30m: At least 2 points must be reliably connected to the protective conductor, and both the beginning and end must be grounded. The metal in cable trays may be used as the EGC as per the limitations. The core requirements for Cable Tray grounding, as per GB 50303-2015, GB 51348-2019, and CECS 31-2023, can be summarized as "metals must be grounded, connections must ensure conductivity, and multiple points must ensure reliability". 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.
