ROOFTOP BLOCK ROOF PIPE SUPPORTS ROOFTOP WALKWAY

What is the spacing between rooftop cable tray supports

What is the spacing between rooftop cable tray 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. The safety of your people and the reliability of your electrical system depend on proper cable tray support spacing. In this blog, we'll focus on support spacing for perforated, ladder and wire mesh cable trays and reference the National Electrical Code (NEC). Where products of five metre lengths or above are packed in bundles, they shall be supported with a minimum of three timber bearers which provide sufficient clearance to accommodate the forks of a forklift truck. Layout isolation pads, (provided by contractor), according to the design and layout.
