    1 Scope

    1.1 These requirements cover Multioutlet Assemblies and factory assembled wiring kits for installation in Multioutlet Assemblies. Multioutlet Assemblies consist of a raceway, multiple outlet wiring devices that provide power for connection of utilization equipment. Multioutlet Assemblies are intended for use in dry locations, other than hazardous (classified) in accordance with the National Electrical Code®, NFPA 70®a. Multioutlet Assemblies are intended to be connected to branch circuits operating at potentials not exceeding 1000 volts between conductors, frequencies between 50 – 400 Hz and DC (Direct Current) circuits.

    a NFPA 70®, National Electrical Code and NEC® are registered trademarks of the National Fire Protection Association, Quincy, MA.

    1.2 Multioutlet Assemblies are intended to be permanently wired.

    1.3 General purpose cord and plug connected outlet assemblies are covered by the following standards:

    a)    The Standard for Relocatable Power Taps, UL 1363; or

    b)    The Standard for Furniture Power Distribution Units, UL 962A.

    1.4 Multioutlet Assemblies may be provided with:

    a) Fuses or other supplementary overcurrent protection;

    b) Switches;

    c) Suppression components;

    d) EMI filters;

    e) LED drivers;

    f) Luminaires;

    g) Ballasts;

    h) Motors;

    i) Control circuits;

    j) Transformers;

    k) Relays;

    l) Indicator lights; and

    m) Other similar equipment.

    1.5 A Multioutlet Assembly may be provided with channels for additional power circuits, control circuits, power limited circuits and communication circuit wiring for audio, video and data.

    1.6 These requirements do not cover surface metal raceways or surface nonmetallic raceways. Surface raceways are evaluated to the following Standards:

    a)    The Standard for Surface Metal Raceways and Fittings, UL 5; and

    b)    The Standard for Nonmetallic Surface Raceways and Fittings, UL 5A.

    1.7 This outline does not cover assemblies that only incorporate receptacles of the GFCI type. These assemblies are covered by the Standard for Ground-fault Circuit-Interrupters, UL 943.

    1.8 This outline contains the following supplements:

    a) Supplement sa – Modular Factory-Wired Floor-Mounted Multioutlet Assemblies; and

    b) Supplement sb – Motor-Operated Multioutlet Assemblies.
