Whether distributing power to equipment rooms, routing network cables in a data center, or feeding production machinery in a manufacturing. Connecting cable trays correctly is essential for system safety, load stability, and long-term performance. Choosing the right one depends on project conditions, load. A cable tray fittings works best when the route conditions are known early and the tray is selected as part of a complete cable management system. It should not be chosen only because it looks similar to another tray type on a small drawing. Routes include 45-degree or 90-degree changes. The following pages address the 2014 National Electrical Code® requirements for cable tray systems as well as design solutions from practical experience. Each example of bends and tee's clearly illustrate proper tray cutting combined with recommended usage of Cablofil accessories.
