The Washington Journeyman Electrician Guide

What Is the Washington Journeyman Electrician License?

In Washington, electricians are certified by the Department of Labor & Industries (L&I) Electrical Program under RCW 19.28 and WAC 296-46B. L&I performs the certification and contractor licensing, and contracts with PSI to administer the computer-based examinations at testing centers across Washington and nationwide. The general journey level (01) certificate authorizes you to perform all types of electrical and telecommunications installations; specialty certificates (02 residential, 06 limited energy, 06A HVAC/refrigeration, and the other categories in WAC 296-46B-920) cover narrower scopes of work.

Performing electrical work in Washington requires both a valid certificate of competency and employment by a licensed electrical contractor — a certificate alone does not let you work for hire. The electrical contractor license, the contractor bond (RCW 19.28.061), and the supervision ratios for trainees all sit on top of the worker certificate, and L&I enforces them with civil penalties of up to $5,000 for a first violation (RCW 19.28.261).

The Requirements

• Register as an electrical trainee: You must hold a current electrical training certificate from L&I and work under the direct supervision of a certified journey level electrician. Trainee work is limited to equipment at 600 volts or less, and your employer (the certified contractor) attests to and verifies your hours. Trainees performing (01) type work must be registered in a general journey level apprenticeship program — the grace period that let some trainees qualify without apprenticeship registration ended July 1, 2026.
• Experience: 8,000 hours of work experience for the (01) journey level exam — no more than 4,000 of those hours may come from specialties that themselves carry a 4,000-hour requirement (RCW 19.28.191), and hours from specialties with less than a 4,000-hour requirement cannot count toward journey level at all.
• Basic classroom instruction: 96 hours of basic classroom instruction for the (01) journey level exam (48 hours is the requirement for the 4,000-hour specialties). L&I verifies the education and the hours in your record before approving you for examination.
• Apply to L&I for examination: L&I must approve your experience and education before you can test — you cannot schedule a PSI exam without the L&I exam approval letter, and in-state applicants apply online through L&I QuickCards. Your approval letter opens a one-year exam period, and your first attempt during that period must consist of all exam sections.
• Pass both exam sections: Pass <strong>each</strong> section of the PSI journeyman exam with 70% or better: Section A NEC & Theory and Section B Washington Codes. Sections you pass stay passed for the remainder of your one-year exam period; sections passed in an earlier period do not carry over.

Certificates renew every 3 years and expire on your birthdate, with 24 hours of continuing education required to renew. Certification is not renewable if it has been expired more than 90 days — after that, retesting is the only route back. L&I also has a reciprocal agreement with Oregon for holders of an Oregon general journeyman (J) or supervising electrician (S) license obtained by examination.

Exam Format: Open Book, PSI

The Washington journeyman exam is <strong>open book</strong>, computer based at PSI, and made of two sections that must both be passed at 70% or better. Washington adopts the <strong>NEC 2026</strong> on <strong>December 31, 2026</strong> (WAC 296-46B-010, adopted by L&I with that effective date); until that date the 2023 edition is the code in force in Washington. Journeyman Practice writes its Washington bank against the NEC 2026. The two sections:

The references are physical books: the NEC with index tabs (tabs cannot be removable, and no handwritten or sticky notes are allowed) and printed, hole-punched copies of Chapter 19.28 RCW and Chapter 296-46B WAC in a three-ring binder. Because both sections are open book, the exam rewards <strong>code navigation</strong> — knowing that the certifying statute is RCW 19.28, that the electrical rules are WAC 296-46B, and where each NEC article lives — over memorization. You must pass <strong>each section</strong> at 70% or better; a strong NEC section does not rescue a failed Washington Codes section.

What the Exam Covers

The PSI content outline for Section A (NEC & Theory) allocates the 60 questions across 17 subject areas, and Section B is a single Washington laws-and-rules block:

• NEC 300–398 Wiring Methods — 10 questions: the largest block — wiring methods and materials across Chapter 3.
• General Trade Knowledge & Theory — 7 questions: electrical theory and general trade knowledge outside the code book.
• NEC 240 Overcurrent Protection — 6 questions: fuses, breakers, and their application (Article 240).
• NEC 250 Grounding & Bonding — 6 questions: system and equipment grounding, bonding, and grounding electrodes (Article 250).
• NEC 230 Services — 4 questions: service entrances and service equipment (Article 230).
• NEC 517–590 Special Occupancies — 4 questions: health care facilities, places of assembly, and other special occupancies (Chapters 5–6).
• NEC 100–110 General Requirements — 3 questions: definitions and code administration (Articles 100 and 110).
• NEC 200–225 / 280–285 Wiring & Protection — 3 questions: use and identification of grounded conductors, branch circuits, feeders, and surge protection.
• NEC 400–480 Electrical Equipment — 3 questions: flexible cords and cables, fixtures, appliances, and equipment for general use.
• NEC 430–450 Motors / HVAC / Generators / Transformers — 3 questions: motor circuits (430), HVAC equipment (440), generators, and transformers (450).
• NEC 600–695 Special Equipment — 3 questions: signs, cranes, elevators, pools, and other special equipment.
• NEC 500–516 Hazardous Locations — 2 questions: classified locations and the wiring methods they require (Article 500–516).
• NEC 700–702 Emergency & Standby — 2 questions: emergency systems, legally required standby systems, and optional standby systems.
• NEC 90 Introduction — 1 question: purpose, scope, and the arrangement of the code.
• NEC 490 Over 600 Volts — 1 question: installations over 600 volts, nominal.
• NEC 705–780 Special Conditions — 1 question: interconnected electric power production sources and related special conditions.
• NEC 800–830 Communications — 1 question: communications circuits, cables, and equipment (Chapter 8).
• Section B: Washington Laws & Rules (RCW 19.28 + WAC 296-46B) — 17 questions: the whole of Section B — certification, contractor licensing, trainee supervision and ratios, scope of work, continuing education, and enforcement.

Section A is overwhelmingly code-based, but 7 of the 60 questions are general trade knowledge and theory, and Section B is entirely state law: RCW 19.28 and WAC 296-46B. Candidates who drill only the NEC tend to give away Section B, where 12 of 17 correct answers are needed to pass. Note also that Washington tests wiring methods (10 questions) more heavily than any other single subject.

How to Prepare

1. Get your certificate path right before you study. Confirm with L&I that your record shows the 8,000 hours (no more than 4,000 from 4,000-hour specialties) and the 96 hours of basic classroom instruction — you cannot schedule the PSI exam without L&I approval.
2. Learn the two rulebooks, not just one. Section B is 17 questions of RCW 19.28 and WAC 296-46B. Know the statutes by number: RCW 19.28.041 (certificate and contractor license), 19.28.161 (trainee supervision and ratios), 19.28.261 (penalties), and the WAC 296-46B series on scope of work and continuing education.
3. Memorize the Washington numbers. Two trainees per journey level electrician is the general statutory cap (RCW 19.28.161) and up to three on a single project is the rule-based maximum (WAC 296-46B-905/-930); the trainee voltage ceiling is 600 V; the first-offense civil penalty is up to $5,000; certificates renew every 3 years with 8 hours of CE per year.
4. Build the NEC chapter map. Grounding in Article 250, overcurrent protection in 240, services in 230, wiring methods in Chapter 3, motors in 430, transformers in 450 — know where each topic lives before you open a single practice question.
5. Drill with the code open and a timer running. Section A is 60 questions in 180 minutes (about 3 minutes each) and Section B is 17 questions in 60 minutes — a different pacing. Answer with the code beside you, then verify the exact section and table.
6. Simulate the full two-section exam. Timed, open-book runs of both sections at least once a week in the final month — including a Section B run without touching the NEC — so no section is decided by unfamiliarity on exam day.

Retaking the Exam

If you fail a section of the Washington journeyman exam, you retake only what you failed. You must wait at least 14 days between attempts, and if you fail any portion of the exam three times within your one-year exam period you must wait 90 days between all further attempts. You have one year from your first attempt to pass all sections; after that year you retake the entire examination. Exam fees are paid to PSI (electrician exams are billed by the hour, in addition to L&I application fees), so check the current L&I/PSI bulletin for the amount before you schedule.

After Licensure: The Path to Master

A certified 01 general journey level electrician can perform all types of electrical and telecommunications installations across Washington. The journey level years are the runway to the master certificate and to contracting. To run an electrical business in Washington you need the electrical contractor license in addition to a certified master or journey level electrician on staff, plus the contractor bond (RCW 19.28.061), and L&I lists code violations among the grounds for denying, suspending, or revoking certification and contractor licenses (RCW 19.28.171). Certificates renew every 3 years on your birthdate with 24 hours of continuing education — the recurring annual minimum is 8 hours (WAC 296-46B-020) — and an initial certification stays valid for 25 to 36 months depending on when you pass and when your birthday falls. Washington also has a reciprocal agreement with Oregon for holders of an Oregon general journeyman (J) or supervising electrician (S) license obtained by examination.
