  • SCOPE

    1 Scope

    1.1 These requirements cover non-enclosed and enclosed pullout switches of the detachable type.

    1.2 These requirements cover pullout switches rated 600 V or less, 400 A or less, with or without horsepower ratings, and with or without high-available fault current ratings.


    1.2 revised July 28, 2005

    1.3 These requirements cover pullout switches mounted in complete enclosure. Such an enclosure may contain meter sockets or neutral assemblies or both.

    1.4 These requirements also cover enclosed pullout switches intended for use as service equipment.

    1.5 These requirements cover non-enclosed pullout switches for use as mains and branches in panelboards, switchboards, and the like.

    1.6 This standard does not cover hinged pullout switches. Such switches are covered in the Standard for Enclosed and Dead-Front Switches, UL 98.

    1.7 These requirements do not cover enclosed pullout switches containing more than one independent switch which are covered by the Standard for Panelboards, UL 67.

    1.8 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
