Washington electrician licensing — what you need to know

Washington licensing authority

Washington licenses electricians through L&I. The 01 General classification authorizes all electrical work; specialty 02 classifications cover specific trades.

License types issued

Washington issues the following electrician license classifications:

• 01 General Electrician
• 02 Specialty Electrician
• 06 Stationary Engineer
• Trainee certifications

Hour requirement

Washington requires 8,000 hours and 96 hours of related supplemental instruction for the 01 General Electrician exam.

Hour requirements typically combine on-the-job experience under a licensed electrician with classroom or related supplemental instruction. Confirm exact totals and qualifying-experience rules with the Washington Department of Labor and Industries (L&I) before submitting an application — requirements occasionally change.

Code edition

Washington adopts NEC with Washington Administrative Code (WAC) amendments. Verify the current adopted edition with L&I.

What candidates should know about prep

• Washington's WAC includes amendments affecting service equipment, grounding, and seismic bracing in some occupancies.
• 01 General requires more hours than the Texas TDLR Journeyman path.
• Trainee certifications must be maintained during apprenticeship hour accumulation.
