Grounding And Bonding Of Cable Trays

Grounding of Stainless Steel Cable Trays

Grounding is required: Metal steel trays (including hot-dip galvanized, stainless steel, and aluminum alloy) must be reliably connected to protective conductors to achieve equipotential bonding and prevent electric leakage and electrification. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. Use the cable tray as the. 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.

Requirements for electrostatic grounding of cable trays

NEC Article 392 governs cable tray grounding requirements. Metallic wire mesh trays must be electrically continuous and properly bonded. If an EGC cable is installed in or on a cable. Table 392. 60(A) “Metal Area Requirements for Cable Trays used as Equipment Grounding Conductors” shows the minimum cross-sectional area of cable tray side rails (total of both side rails) required for the cable tray to be used as the Equipment Grounding Conductor (EGC) for a specific Fuse Rating. This article provides a comprehensive framework that governs various aspects of cable tray installations, including the types of cables that are deemed acceptable for use, requirements for grounding and bonding, and stipulations regarding tray fill capacity.
