Significant 2017 NEC & WAC 296-46B Changes

The latest Special Edition of the Washington State Department of Labor & Industires "Electrical Currents" newsletter detailed some of the significant changes in the 2017 National Electrical Code (NEC®) and WAC 296-246B Electrical Safety Standards, Administration and Installation electrical rules. the department adopted revisions to WAC 296-46B, including adoption of the 2017 NEC® with an effective date of July 1, 2017. Installations made under any electrical permit purchased on or after July 1, 2017 are subject to the new requirements. The recent rulemaking process was necessary to align the previous July 2014 WAC 296-46B (based on the 2014NEC®) with the 2017 NEC®. The department adopted very few amendments to the NEC®. The newsletter does not cover all changes and is meant to assist affected companies in becoming aware of some of the significant changes. The explanations vary from the actual code language, and it is recommended you refer to the full revision that will soon be available under the Electrical Laws & Rules section of the Washington State Department of Labor & Industries site.
