What is a Cable Tray System?
Per the National Electrical Code, a cable tray system is "a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways."
What does this mean?
    • Cable trays support cable the way that roadway bridges support traffic.
    • A bridge is a structure that provides safe passage for traffic across open spans.
    • Cable tray is the bridge that allows for safe transport of wires across open spans.
    • Therefore, think of cable tray as the structural component of a building's electrical system.
What standards / guidelines are available for cable tray systems?
    1. The National Electrical Code publishes the standards for all types of electrical applications. Articles 318, 250, and 800     cover various aspects of cable tray systems.
    2. NEMA, (National Electrical Manufacturers Association), is an association comprised of the
        major cable tray manufacturers in the industry. This committee has published three
        documents to date: NEMA VE1, FG1 and VE2.
        NEMA VE1 covers general cable tray definitions, manufacturing standards, performance
        standards, test standards, and application information. Free Download of this document is
        available on the NEMA website.
        NEMA FG1 addresses the standards for fiberglass cable tray systems Free Download of
        this document is available on the NEMA website.
        NEMA VE2 is a cable tray installation guideline which covers receiving and unloading
        material, storage of material, and general installation practices. Free Download of this
        document is available on the NEMA website.
CTI, (Cable Tray Institute), is a trade association comprised of the major cable tray manufacturers in the industry and was formed to provide specifiers, designers, and installers information on the advantages of using cable tray systems over other types of products. (i.e. conduit, ladder rack, etc.)

       Ladder cable tray is generally used in applications with intermediate to long support spans,
       12 feet to 30 feet.

    2. Solid Bottom Cable Tray provides:
       a. Non-ventilated continuous support for delicate cables with added cable protection
           available in metallic and fiberglass.
       b. Solid bottom metallic with solid metal covers for nonplenum rated cable in environmental
           air areas
