Home / Number of holes on one side of the cable tray
The number of drill holes is dependent on the height and width of the cable trays. Recommendation: For side height 60 mm = 4 screws per connector; for width 300 mm = 3 screws per joint plate. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. With unmatched quality and service, we offer a variety of styles, materials and finishes to support virtually any cable management. Hubbell's NEXTFRAME® Ladder Tray is the effective and widely used cable runway that supports and delivers bundles of cable between cabinets, racks, and closets, along walls, and suspended from ceilings. National Electrical Code (NEC) specifies the capacities of cables rated at 2000 volts or less in cable trays.
When solid bottom trough tray is installed outdoors, or indoors in humid locations, and EMI/RFI shielding protection is not required, it is recommended that 1⁄4"weep holes be drilled into the tray bottoms at
