43、ing molded-on or assembled-on ttings, rated 600 V maximum, and intended for use in non-hazardous locations in accordance with the National Electrical Code, ANSI/NFPA 70. 1.2 This Standard also species the requirements for molded-on general-use attachment plugs and cord connectors. 1.3 This Standard

44、also species the requirements for hospital grade attachment plugs and cord connectors. 1.4 This Standard also species the requirements for cord restraint devices. 1.5 These requirements do not cover cord sets intended for temporary outdoor use not to exceed 90 days with outdoor equipment, Christmas-

45、tree, and other seasonal decorative-lighting outts. Such devices are covered by the Standard for Outdoor Seasonal-Use Cord-Connected Wiring Devices, UL 2438. 1.6 These requirements cover devices with remote control features that comply with the Standard for Solid-State Controls for Appliances, UL 24

46、4A. See also 9.9. Devices Employing Remote Control Features. Compliance with the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1, and/or the applicable Part 2 standard from the UL 60730 series fullls these requirements. 2 Components

47、2.1 Except as indicated in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 2.2 A component is not required to comply with

48、a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended

49、 conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.
