Cable Tray Replacement Precautions
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). Cable tray systems can pose serious safety risks if not properly designed or installed.
