Practices for grounding and bonding of cable trays
In addition to providing an electrical connection between the cable tray sections and the EGC, the grounding clamp mechanically anchors the EGC to the cable tray so that under fault
Cable Tray Installation Rules (NEC 392) – Electrical Trader
The cable tray can act as the equipment grounding conductor (EGC) if it meets specific conditions. It must be clearly identified as an EGC, properly bonded to maintain electrical continuity,
Earthing or Bonding a Metallic Cable Tray: What the Regs Really Say
If you must earth a tray for functional reasons (static discharge, RFI), do it at one end only. Bonding both ends can form a loop, increasing magnetic coupling and nuisance RCD trips.
Cable Tray Grounding: Power, Instrumentation, and Telecommunications
The most desirable design is to separate power and signal cables in separate cable trays, or to separate wiring systems by a barrier. The sensitivity of signal systems depends on a number of complex factors.
