| NEC — National Electrical Code (NFPA 70) | 2020 NEC (NFPA 70), as amended by Louisiana. ADOPTING TEXT VERBATIM, LAC 17:I.115.A: "National Electric Code (NEC), 2020 Edition, and the standards referenced in that code for regulation of construction in this state." NOT the 2023 NEC. SCOPE: statewide, both residential and commercial (applies_to left NULL because the column only accepts residential/commercial) — the LSUCCC is the mandatory statewide construction code under La. R.S. 40:1730.28(A), which commands that the council "shall evaluate, adopt, and amend only the latest editions" of the listed codes (verbatim, read first-hand this run); administered by the Louisiana State Uniform Construction Code Council, Office of the State Fire Marshal, Dept. of Public Safety and Corrections. NOTE THE STATUTORY SPELLING: both R.S. 40:1730.28(A)(8) and the rule say "National Electric Code", not "National Electrical Code" — a search of Louisiana law for "National Electrical Code" MISSES THE ADOPTION ENTIRELY. THE STATUTE NAMES NO EDITION: R.S. 40:1730.28(A)(8) reads, in its entirety, "National Electric Code." The edition exists ONLY in the rule, so the rule is the only place the answer can be read. Louisiana electrical is NOT folded inside the adopted I-Codes: R.S. 40:1730.28(A)(1) excludes IBC "Chapter 27-Electrical" and (A)(3)(a) excludes IRC "Part ... VIII-Electrical", so the NEC is the sole statewide electrical code and stands on its own. This CONFIRMS first-hand the "2020 National Electrical Code" note previously carried as hearsay on the Louisiana IBC row. | LAC 17:I.115 (Louisiana State Uniform Construction Code — National Electric Code; formerly LAC 55:VI.301.A.7), adopted as part of Chapter 1 by LAC 17:I.101.A effective 2023-01-01; statutory mandate La.
