What is the spacing between lighting cable tray supports

Home / What is the spacing between lighting cable tray supports

Generally, standard trays require supports every 6 to 10 feet, while heavy-duty, long-span trays can handle distances of up to 20 feet between supports. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. In this blog, we'll focus on support spacing for perforated, ladder and wire mesh cable trays and reference the National Electrical Code (NEC). Where products of five metre lengths or above are packed in bundles, they shall be supported with a minimum of three timber bearers which provide sufficient clearance to accommodate the forks of a forklift truck. Ladder cable tray is available in widths of 6, 9, 12, 18, 24, 30, 36, 42 and 48 inches with rung spacings of 6, 9, 12 or 18 inches. Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency.
