Cable routing for long-span cable trays
Cable tray routing should be coordinated with building layout and other services (pipes, ducts, mechanical systems): Plan main routes along corridors, pipe racks, or dedicated cable trenches to minimize crossings and congestion. Long-span cable trays have a larger support span than ordinary cable trays, with a more sophisticated structural design and greater load-bearing capacity. They are not only suitable for the overhead laying of indoor and outdoor cables in industrial and mining enterprises such as petrochemical. Hubbell's NEXTFRAME® Ladder Tray is the effective and widely used cable runway that supports and delivers bundles of cable between cabinets, racks, and closets, along walls, and suspended from ceilings. The Ladder Tray features light, rugged, tubular steel construction. It is designed for. association representing the major electrical equipment manufac-turers in the U. It provides speed of deployment, structural integrity, cable protection and ease of use to drive business results.

Cables without armor are run in cable trays
The cables identified as Type TC-ER (Exposed Run) can be installed in industrial establishments for the connections between the cable trays and the equipment without metal conduits or armored cables Type MC (Metal Clad Cable); this kind of connections is called Open Wiring. Type TC – Tray Cable – (NEC Article 336) –Power and control tray cable type TC is a factory assembly of two or more insulated conductors, with or without associated bare or covered grounding conductors, under a non-metallic jacket. Pictured here are:. UL Listed shielded cables (THHN/THWN or TFN) built for the uses specified by art. 336 of ANSI/NFPA 70 “National Electrical Code” (NEC) and suitable for use in Class I, Division 2, Hazardous Locations. 8 meters (6 ft) of cable extends from the tray for a connection to a motor or other electrical device, cables without an ER rating must be either armored (type MC) or installed in conduit or another. Tray cable types TC, ITC and PLTC are permitted in cable trays by the NEC. CEC 12-904 (2) indicates that no raceway shall contain conductors of a different source unless they have metal armor.
