Cable tray grounding is essential to provide a safe path for fault currents, minimizing the risk of electric shock, fire, or equipment damage. Metallic trays, including their hangers and supports, must be electrically continuous and bonded to the grounding system of the facility, as required by NEC Article 250 and Article 392 .
Metallic Cable Trays Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified
However, while wire mesh trays offer mechanical and thermal advantages, proper grounding and bonding are critical
According to industrial standards, when cable trays are used as equipment grounding conductors, there is a minimum
Cable tray systems that contain signal and communication circuits should be grounded and, in some situations
Cable tray systems that contain signal and communication circuits should be grounded and, in some situations, shielded from
