Maximum cable load per meter of cable tray

Cable tray load capacity refers to the maximum amount of weight a tray system can safely support across a specified span distance without permanent deformation or structural failure. Load ratings are typically measured in kilograms per meter or pounds per foot. Manufacturers determine load capacity. The weight of your cables is the main load your tray carries. Armoured cables. Proper tray and ladder sizing ensures safe, efficient, and maintainable electrical installations in all engineering applications. IEC 61537 and IEC 60364 require evaluating tray dimensions based on cable quantity, type, and layout configuration. Our cable tray load calculator. [pdf]
