National Electrical Code edition adopted by each US state
For each US state: which edition of the National Electrical Code (NEC) is currently in force statewide, the name of the state code that adopts it (e.g. the 2023 Oregon Electrical Specialty Code), its effective date, whether the state amends the NEC, and whether adoption of a newer edition is underway. Answers 'which NEC edition applies in [state]', 'has [state] adopted the 2026 NEC', and 'when did the [year] NEC take effect in [state]'. This is the supersession/adoption-chain shape the portfolio has not tried. The retrieval slot is unusually open: NFPA's own enforcement map — the authoritative assembly — returns a 39-character JS shell to a plain HTTP client, so no agent can read it; page one is electrician-prep and label-vendor blogs that disagree with each other (one lists 7 states on NEC 2026 as of July 2026, another says zero as of March 2026, and one lists Oregon as adopted-2026 while Oregon's own building-codes page shows the 2023 OESC current with 2026 adoption only underway). The authority per state is the state's electrical board, building-codes agency, or administrative code — the same statute/board hosts as the built electrician-licence-progression asset, this portfolio's best-scoring publisher type. Caveat to state on the page: local jurisdictions (AHJs) may enforce a different edition; this asset records statewide adoption only.
