392.7.Grounding. (A) Metallic Cable
Trays.
All metallic cable trays shall be grounded as required in Article 250 regardless of whether or not the cable tray is being used as an equipment grounding conductor (EGC).
The EGC is the most important conductor in an electrical system as its function is electrical safety.
There are three wiring options for providing an EGC in a cable tray wiring system: (1) An EGC conductor in or on the cable tray. (2) Each multiconductor cable with its individual EGC conductor. (3) The cable tray itself is used as the EGC in qualifying facilities.
