The main cable tray connection methods include splice plates, bolted connections, quick connect systems, fish plates, clamps, and welding. en completely installed, without damage either to conductors or structural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when. Prohibited Areas: Cable trays cannot be used in hoistways or enclosed spaces and must remain accessible. Grounding: Metallic trays can serve as equipment grounding conductors (EGC) if they meet NEC requirements. This guide breaks down the process step by step. The following pages address the 2014 National Electrical Code® requirements for cable tray systems as well as design solutions from practical experience.
