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.
