How to ground the mesh cable tray in a low-voltage electrical room
If a wire mesh cable tray is supporting cable with a built-in equipment grounding conductor or control or signal cables, then the tray should have a low impedance path to a non-system ground to reduce noise and remove induced or stray currents. In addition to providing an electrical connection between the cable tray sections and the EGC, the. Cable tray systems have become an essential component in the infrastructure of modern commercial buildings, smart offices, data centers, and various industrial facilities. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control. that system to lose its UL Classification. If you take what UL states literally, ANY cut to tray (ladder or wi e) would cause a loss of UL Classification. 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. [The cable tray may only be used as an EGC in qualifying facilities as stated.
