Cable trays: Perforated and ladder-type trays, galvanized steel. The primary rulebook used in the safe use of cable trays is NEC Article 392. This is a description of how to select, install, and support these metal or plastic frames, on which electrical wires are installed. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d. Cable trays are components used in the wiring of buildings to support insulated cables and organise them to be hidden from view. Supports and accessories: Channel supports, brackets, hangers, clamps, tray covers, and couplers.
