Cable trays must be grounded
All metallic cable trays must be grounded as outlined in NEC Article 250. This precaution helps prevent electrical shocks and equipment malfunctions. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control. Cable Types: Only use conductors rated for open-air environments, such as Tray Rated (Type TC) or Metal-Clad (Type MC) cables. Clearances: Maintain at least 12 inches of vertical clearance above trays for installation and maintenance access (2026 NEC update). Grounding in cable trays is an important practice to increase electrical safety and prevent. The core requirements for Cable Tray grounding, as per GB 50303-2015, GB 51348-2019, and CECS 31-2023, can be summarized as "metals must be grounded, connections must ensure conductivity, and multiple points must ensure reliability".
