Grounding of cable tray supports
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. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. If you take what UL states literally, ANY cut to tray (ladder or wi e) would cause a loss of UL Classification. For example, when a straight section of tray is cut to length and used in conjunction with a factory fitting — this installation would also. 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.
