Home / Does the cable tray include load-bearing supports
Cable trays must be adequately supported to carry the weight of cables plus any additional loads (such as snow or ice for outdoor installations). Use supports (wall brackets, trapeze hangers, or pedestal supports) at intervals consistent with the tray load rating and manufacturer. When supporting small diameter multi-conductor control and instrumentation cables, 6, 9, or 12-inch rung spacings should be specified. This publication is intended as a practical guide for the proper and safe* installation of cable ladder systems, cable tray systems, channel support systems and associated supports. For proper installation, design, and maintenance, adherence to international standards is essential. Unlike conduit systems, cable trays allow cables to be laid in bundles, improving accessibility, heat.
Where cable ladder and cable tray support systems are fixed to primary supports (e.g. structural steel work or elements of the building) it is important to ensure that the primary supports are strong
