Notes : (1) The insulation temperature rating is marked on the surface of the flexible cord.(2) See Clause 6.9.7 for increasing the insulation temperature rating using sleeving.
(3) Flexible cord that is suitable for use in a wet location is surface marked with a ″W″ or ″Water Resistant″.********* a parallel cord, refer to UL817 *********10.6.2 A conductor or flexible cord that is routed through the chain of a chain pendant luminaire shall have a minimum 0.80 mm (0.032 in) nominal insulation, and if a cord, it shall be at least Type SPT-1. A grounding conductor may be uninsulated. 你的问题是什么呢？ 依然 发表于 2013-5-30 15:40 static/image/common/back.gif
