19、for the Fourth Edition of the Standard for Stage and Studio Luminaires and Connector Strips, UL 1573; PROPOSED EFFECTIVE DATE SUMMARY OF TOPICS 1. This bulletin addresses and resolves the comments received in response to ULs Subject 1573 proposal bulletin dated March 29, 2004, proposing revisions to
20、 the Fourth Edition of the Standard for Stage and Studio Luminaires and Connector Strips, UL 1573. The proposals have been revised to address the following areas (refer to Appendix A for full details): Leakage Current Test - UL proposes that power supply cord-connected UL 1573 products be required t
21、o comply with a leakage current test. Leakage Current Limits - UL proposes that leakage current limits of (a) 4.0 MIU apply to power supply cord-connected products that meet certain criteria; and (6) 0.5 MIU for all other power supply cord-connected products. New Glossary Entries - UL proposes sever
22、al new Glossary definitions, including Fixed Equipment, Portable Equipment, and Stationary Equipment, to assist in understanding the application of the new and revised requirements. Power Supply Cord-Connected Connector Strip - UL proposes new paragraph 29A.2.9 to indicate that all circuits within t
23、he connector strip need to be energized during the conduct of the leakage current test and, where applicable, the location(s) for the leakage current warning marking proposed in Figure 60A. 1. Product Use Categorization - UL proposes new paragraphs 2.5.1 - 2.5.3 to specify that a product needs to co
24、mply with the requirements for all applicable product-use categorizations (fixed, portable, stationary) where the manufacturer intends the installer to choose how the product is used. Leakage Current Measurement Circuits - UL proposes new figures showing the leakage current measurement circuits in a
