Cables inside cable trays must be run through conduits
Standard tray cables must be placed in conduit when run underground unless they are specifically marked for direct burial, and outdoors conduit can provide additional defense against UV exposure and extreme weather. Cable trays allow easy access for maintenance, which is one of their greatest advantages over conduit. TC-ER-rated cables can be installed in exposed runs outside the cable tray, up to 6 feet between the cable tray and connected equipment, and without conduit—provided that the cable is secured and. Cable tray types, fill rules for single-conductor and multiconductor cables, ampacity derating, separation requirements, and when to use tray vs conduit.
