Home / Reliable grounding of galvanized cable trays
Copper stranded wire, galvanized flat steel, or metal components used to install supports along the cable trays can serve as the main grounding conductor. 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 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". However, the main principle should always be to ensure safe and effective grounding.
Where cable tray systems contain only signal and communication circuits that operate at low energy levels, power grounding per NEC Section 318-7 is not appropriate, but cable tray grounding for
