Dropouts: These are pre-manufactured openings in the bottom or side of the tray that allow cables to exit smoothly. The two most common methods to transition from a cable tray to the equipment are: Cables or conductors leaving the cable tray and entering the equipment through a raceway with a bushing on the end (see image A). 21 Cable tray run is Substation or PIB all cable trays shall have a minimum of 200mm clear space above the tray. Factor in clearance, load capacity, and cable separation needs from the get-go. This includes: Needs Analysis: Assess the current and future demands of the system to properly size the tray.
Indoor cable lines should preferably be laid in cable trays or conduits; outdoor cable lines should preferably be laid in cable trenches or buried in protective conduits. The protective conduits should meet the requirements for pressure resistance and environmental corrosion. Medium and low voltage power distribution systems should preferably use single busbars, single busbar sectionalized systems, or cable wiring. However, any installation must adhere strictly to the National Electrical Code (NEC) standards. Here is the summary of the main points found in NEC Article. This article explains the main requirements and good practices for cable tray systems, including tray types, materials, loading, supports, bonding, cable selection, and installation details.
