  • SCOPE

    1 Scope

    1.1 These requirements cover track lighting systems intended for permanent connection to sources of supply in commercial or residential ordinary locations in accordance with the National Electrical Code, NFPA 70. The track lighting systems covered by this standard are rated:

    a)    300 volts or less;

    b)    150 volts or less to ground; and

    c)    50 amperes or less.

    1.2 Lighting track is intended to be permanently installed and permanently connected to a branch circuit not exceeding 277 volts, nominal to ground, and 50 amperes.

    1.3 These requirements cover:

    a)    Track networks consisting of track and connectors;

    b)    Mono-, duo-, and multi-point canopies;

    c)    Incandescent, fluorescent, and high intensity discharge (HID) luminaire assemblies intended to be electrically connected to and physically supported by the track in track networks and canopies;

    d)    Mounting means for the track; and

    e)    Accessories.

    1.4 These requirements do not cover:

    a)    Busways intended for lighting, receptacles, or other general-purpose adaptors covered by the Standard for Busways, UL 857, and intended for use in accordance with Article 364 of the National Electrical Code, NFPA 70; or

    b)    Track lighting systems for marine use aboard a ship or boat.

    1.5 Track lighting systems are not intended for use:

    a)    In wet or damp locations;

    b)    In installations where the track is concealed;

    c)    In hazardous locations;

    d)    Where subject to physical damage;

    e)    Where the track is extended through walls or partitions of building structures;

    f)    Where subject to corrosive vapors; or

    g)    In storage battery rooms.

    1.6 A track lighting luminaire assembly that uses a tungsten-halogen lamp, fluorescent lamp, or high-intensity-discharge lamp shall also comply with the applicable requirements from the Standard for Luminaires, UL 1598.

    1.7 Light emitting diode (LED) components and subassemblies integral to lighting track or a luminaire assembly covered by this standard shall comply with the applicable requirements of the Standard for Light Emitting Diode (LED) Equipment for Use in Lighting Products, UL 8750.
