UL has released a new edition of UL 1088, the standard for Temporary Lighting Strings. The 7th edition can be purchased from the UL website. This new edition reflects the latest ANSI and SCC approval dates. There are national differences only where standards (U.S. vs. Canadian) are referenced. However, the body of the standard is technically identical for Canada and the U.S.
“1.1 These requirements cover temporary lighting strings rated not more than 20 A, 125 V, intended for indoor and outdoor use to provide temporary illumination during the period of construction, remodeling, maintenance, repair, or demolition of buildings or structures, or similar activities, in accordance with the Canadian Electrical Code (CE Code), Part I, CSA C22.1, Section 76, and the U.S. National Electrical Code (NEC), ANSI/NFPA 70, Article 590.
1.2 These requirements cover temporary lighting strings consisting of a factory assembly of flexible cord, or cable, incorporating at least two non-replaceable light sources or two lampholders provided with lamp guards. The complete assembly is intended for connection to a branch circuit.”
