Effective February 20, 2016
Effective Date (see Schedule below): February 20, 2016
Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.
Overview of Changes: UL 458 5th edition was revised to edit supplementary protectors in the output alternating circuits of recreational vehicle inverters for consistency and compliance with Article 551.43 of the National Electrical Code, NFPA 70. Specific details of new/revised requirements are found in table below.
