Spacing of cable tray reinforcement supports
The NEC requires that cable trays must be supported by members at an interval specified by the cable tray manufacturer, but not more than 5 feet for horizontal runs to support the weight of the cables and other loads. 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). These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety.

Distance between large-span cable tray supports
For ladder cable trays supporting large power cables, 9-inch or wider rung spacings should be selected. Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and industrial applications. 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). Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency.
