All metallic cable trays shall be grounded as required in Article 250. The EGC is the most important conductor in an electrical system as its function is electrical. 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). Prohibited Areas: Cable trays cannot be. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. 1 allows the. Trays are fabricated from galvanized steel, stainless steel, aluminum, or flame-retardant nonmetallic materials. Aluminum is lightweight and naturally corrosion-resistant, making it common in chemical plants and outdoor runs. Stainless steel handles the most demanding corrosive environments. You should consider it as a series of instructions that make the buildings resistant to.
