15 UL Rapid Shutdown The 2017 NEC code panel meeting revised a proposal to include new requirements for rapid shutdown protection internal to a PV array and includes the following options: Option 1: List and label or field-label PV array as a rapid-shutdown PV array. Option 2: Limit control conductors within the array boundary to 80 V or less within 30 seconds of rapid-shutdown initiation. Option 3: Install nonmetallic PV array with no exposed wiring and array more than 8 feet from any grounded metal parts * Implementation of Option 1 requires development of a safety standard for evaluation and certification of rapid-shutdown products for use in PV arrays. CMP 4 added a delayed adoption date, specifying that (B)(2) shall become effective January 1, to allow time for the standard s development process August 2, Solar Energy Industries Association 15
