22、 exceed 90 days with outdoor equipment, Christmas-tree, and other seasonal decorative-lighting outts. Some outdoor seasonal-use cord-connected wiring devices employ additional devices such as photoelectric sensors, fuses, supplementary protectors, timers, audio, asher control or synchronized feature
23、s. Products employing additional devices shall meet the intent and testing described in this Standard. 1.2 These requirements only cover devices of the 2-pole, 3-wire, 5-15 conguration as shown in Wiring Devices Dimensional Specications, ANSI/NEMA WD6. 1.3 These requirements cover devices with remot
24、e control features that comply with the Standard for Solid-State Controls for Appliances, UL 244A. See Devices Employing Remote Control Features, Section 11. Compliance with the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1, and/or
25、 the applicable Part 2 standard from the UL 60730 series fullls these requirements. 1.4 These requirements cover devices with audio features that comply with the Standard for Audio, Video, and Similar Electronic Apparatus Safety Requirements, UL 60065, or the Standard for Audio/Video, Information an
26、d Communication Technology Equipment Part 1: Safety Requirements, UL 62368-1. See Devices Employing Audio Features, Section 12. 1.5 These requirements are intended to be used with the Standard for Cord Sets and Power-Supply Cords, UL 817. 2 Components 2.1 Except as indicated in 2.2, a component of a
27、 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 a specic requirement that: a) Involves a feature
28、 or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are in
29、complete 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.

36、e with Wiring Devices Dimensional Specications, ANSI/NEMA WD6. 5.4 A blade used in an attachment plug cap shall comply with the Standard for Attachment Plug Blades for Use in Cord Sets and Power-Supply Cords, UL 1659. Exception No. 1: A blade which has crimp connections that are also soldered or wel
37、ded need not comply with the performance requirements in the Standard for Attachment Plug Blades for Use in Cord Sets and Power-Supply Cords, UL 1659. Exception No. 2: A blade which is welded or is made mechanically secure and soldered directly to the conductor connections need not comply with the p
38、erformance requirements in the Standard for Attachment Plug Blades for Use in Cord Sets and Power-Supply Cords, UL 1659.
