How often is the NEC updated?

The National Electrical Code (NEC) is updated every three years. This regular update cycle allows for the latest advancements in electrical technology, safety practices, and industry needs to be incorporated into the code. The three-year timeline ensures that the NEC remains relevant and up to date with current practices, addressing issues and concerns that may arise within that period based on feedback from professionals in the field, technological advancements, and changes in safety standards.

While some standards and codes in other fields may have different intervals for updates, the NEC’s three-year update cycle balances the need for timely revisions with the practicality of ensuring widespread understanding and adoption within the industry. This frequency supports both ongoing education for professionals and the incorporation of new safety measures that protect both workers and the public.
