Washington – RCW/WAC

This course is designed to help electricians navigate the intersection of Washington state electrical laws (RCW 19.28), administrative codes (WAC 296-46B), and the National Electrical Code (NEC). Participants will examine specific code changes and regulatory mandates, beginning with the defined roles of the Department and Board, the various tiers of electrical licensing, and the critical “Like-in-Kind” standard for repairs.

It further explores critical safety requirements and administrative procedures essential for maintaining a valid contractor’s license, including bond requirements, trainee supervision ratios, and the specific scopes of work for general and specialty licenses. Technical modules focus on Washington-specific amendments to the NEC, such as the “15-foot rule” for interior raceways, mandatory concrete-encased electrode (CEE) inspections, and the selective coordination of emergency systems. By the end of this session, attendees will gain an understanding of the legal and technical milestones required for successful inspections, utility connections, and long-term compliance in the Washington electrical trade.
