Working notes
Register history for 8 AAC 63.010 in the official filings: the 2018-edition adoption took effect April 24, 2020 (Register 234); the Aug. 8, 2025 amendment (Register 255) changed only the introductory exceptions language and added a plumbing-certificate reciprocity rule at 8 AAC 90.111 - the edition did not change. STALE COMPILATIONS FLAGGED, electrical-row pattern repeating: older Dept. of Labor booklets still circulating adopt the 2009 (2011 booklet), 2012 (2014 booklet), and 2015 (2017 booklet) UPC editions; the April 2020 compilation matches the current regulation.
