What Is the Washington 01 General Journey Level Electrician Certificate?

Washington recognizes two broad types of electrician certification: General Journey Level and specialty electrician. The General Journey Level certificate is identified as classification 01.

A certified 01 electrician may perform all types of electrical and telecommunications installations within Washington's legal electrical construction trade. That broad scope is the biggest difference between 01 and a specialty certificate.

Washington Changed the In-State Path to 01 Certification

Washington moved the General Journey Level pathway to an apprenticeship-based model. A temporary transition period existed for certain trainees who had enough qualifying experience before July 1, 2023, but that allowance required L&I to receive the complete exam application and supporting documents before July 1, 2026.

That deadline has now passed. For a new in-state candidate in September 2026, the normal route is completion of an approved 8,000-hour electrical construction apprenticeship under Washington's apprenticeship laws.

Out-of-state electricians, military applicants, and candidates using Washington's Oregon reciprocity route can have different qualification rules. Those paths should be reviewed separately before applying.

The Standard 01 Apprenticeship Requirement

The current standard Washington path requires successful completion of an 8,000-hour electrical construction trade apprenticeship program approved under Washington apprenticeship law.

Within those 8,000 hours, at least 4,000 hours must involve new industrial or commercial electrical installations under the required supervision.

Registered apprenticeship programs also include their own related supplemental instruction. Candidates should follow the education requirements of their approved apprenticeship rather than treating 96 hours as the entire classroom component of an apprenticeship.

How Specialty Experience Can Count Toward 01

Washington allows a limited amount of experience from qualifying electrical specialties to count toward the 8,000-hour General Journey Level requirement.

No more than 4,000 total hours from qualifying 4,000-hour specialties can be credited toward 01. Experience from specialties requiring less than 4,000 hours does not count toward qualification for the General Journey Level examination.

Examples of 4,000-hour specialties include:

• Residential 02
• Pump & Irrigation 03
• Signs 04
• Limited Energy 06
• HVAC/Refrigeration 06A
• Nonresidential Maintenance 07

Even with specialty credit, the candidate still needs the required new industrial or commercial installation experience. The 01 certificate is broad, so Washington expects broad supervised experience.

How to Apply for the Washington 01 Exam

1. Complete the qualifying 01 apprenticeship or another recognized pathway.
2. Make sure your L&I record reflects qualifying education and experience.
3. Submit the correct electrician examination application.
4. Provide any required affidavits, apprenticeship completion records, or supporting documentation.
5. Wait for L&I to determine examination eligibility.
6. Receive the exam approval information and Exam Unique ID.
7. Schedule the exact 01 General Journey Level Electrician exam with PSI.
8. Prepare for NEC & Theory and Washington Codes.
9. Pass each required section with at least 70 percent.
10. Complete L&I's remaining certification steps.

Washington tells electrician candidates not to schedule with PSI until L&I has approved the examination request. Schedule the exam listed in your approval, not the exam that merely has the most familiar title.

Washington 01 General Electrician Exam at a Glance

The current General Journey Level Electrician examination has two required sections: NEC & Theory and Washington Codes.

Unlike the General Master Electrician and General Administrator examinations, the 01 electrician exam does not have a separate Major Load Calculations section. Calculations can still appear inside NEC & Theory.

Current 01 General Electrician Exam Blueprint

Wiring Methods is the largest single technical category. Grounding & Bonding and Overcurrent Protection follow closely, while General Trade Knowledge & Theory adds another substantial group of questions.

Wiring Methods Is the Largest Technical Category

Wiring Methods currently carries about 10 questions, making NEC 300-398 the largest technical block on the 01 electrician exam.

Review:

• Raceway types and permitted uses
• Cable wiring methods
• Boxes and fittings
• Box fill
• Conduit and raceway fill
• Securing and supporting requirements
• Wet and damp locations
• Underground installations
• Physical-damage protection
• Conductor installation rules
• Special wiring methods

Open-book candidates should know approximately which article controls the wiring method before reaching for the index. That one habit can save a surprising amount of exam time.

Grounding, Bonding, and Overcurrent Protection

Grounding & Bonding and Overcurrent Protection each carry about six questions in the current outline.

Grounding and bonding topics include:

• Grounding electrode systems
• Grounding electrode conductors
• Equipment grounding conductors
• Main bonding jumpers
• Services
• Separately derived systems
• Metallic systems and equipment bonding
• Ground-fault current paths

Overcurrent topics include:

• Branch-circuit protection
• Feeder protection
• Standard overcurrent-device ratings
• Conductor protection
• Tap rules
• Equipment-specific protection
• Motor and transformer protection where applicable

Services, Feeders, Branch Circuits, and Conductors

A General Journey Level electrician needs broad power-distribution knowledge. Services currently carry about four questions, while Wiring & Protection contributes another three.

Study:

• Service conductors
• Service equipment
• Disconnecting means
• Feeder sizing
• Branch-circuit requirements
• Conductor ampacity
• Temperature limitations
• Adjustment and correction factors
• Parallel conductors
• Voltage drop
• General electrical calculations

The broad 01 scope means you should be comfortable moving between residential, commercial, industrial, and specialty-type installation questions without mentally changing careers every time the occupancy changes.

Motors, Transformers, Generators, and Equipment

The 01 exam includes questions on motors, HVAC equipment, generators, transformers, and other electrical equipment.

Review:

• Motor conductor sizing
• Motor overload protection
• Short-circuit and ground-fault protection
• Controllers
• Disconnecting means
• Transformer conductor rules
• Transformer overcurrent protection
• Separately derived systems
• Generator installations
• Transfer equipment
• HVAC equipment

Motor questions are famous for putting several different protection rules into the same problem. Slow down long enough to identify which conductor, device, or piece of equipment the question actually wants protected.

Special Occupancies and Special Equipment Matter

General Journey Level certification is broad, so the exam includes more than everyday branch circuits and services. The current outline includes special occupancies, hazardous locations, special equipment, emergency systems, standby systems, special conditions, and communications.

Be familiar with topics such as:

• Health-care facilities
• Hazardous locations
• Commercial garages and fuel-related areas
• Swimming pools and spas
• Electric signs
• Fire pumps
• Emergency systems
• Legally required standby systems
• Optional standby systems
• Photovoltaic systems
• Energy storage and interconnected systems
• Communication systems

You do not need to memorize every unusual installation. You do need to know where these subjects live in the NEC and how to find the controlling rule.

General Trade Knowledge and Electrical Theory

General Trade Knowledge & Theory currently accounts for about seven questions. These questions test knowledge that cannot always be solved by simply finding one sentence in the NEC.

Practice:

• Ohm's law
• Voltage, current, resistance, and power
• Series and parallel circuits
• Single-phase calculations
• Three-phase calculations
• Voltage drop
• Transformer relationships
• Motor-related math
• Conductor calculations
• General trade mathematics

Field experience helps enormously, but theory problems still need practice on paper. Being able to wire a three-phase motor is useful. Being able to solve the exam's math before the calculator gets emotionally involved is useful too.

Washington Codes Is a Separate Required Section

The Washington Codes section currently contains about 17 questions and allows one hour. It focuses on RCW Chapter 19.28 and WAC Chapter 296-46B.

Study:

• Electrician certification
• Electrical trainee requirements
• Apprenticeship-related rules
• Electrical contractor requirements
• Permits
• Inspections
• Supervision
• Experience documentation
• Exam rules
• Washington NEC amendments
• Enforcement and penalties
• Continuing education and renewal

Washington Codes must be passed separately. A great NEC score cannot average out a weak Washington law score, so RCW and WAC deserve scheduled study time.

The Current Exam Still Uses the 2020 NEC

Washington's current PSI Candidate Information Bulletin identifies the 2020 National Electrical Code for electrical licensing examinations. The Washington references are the current versions of RCW Chapter 19.28 and WAC Chapter 296-46B.

The Washington General Electrician Book Package combines the three core references: the 2020 NEC, RCW Chapter 19.28, and WAC Chapter 296-46B.

The Washington 01 Exam Is Open Book

Washington electrical examinations are open book, but PSI and L&I enforce rules about permitted reference materials.

Current rules allow:

• The 2020 NEC
• Original copyrighted electrical references
• Permanent index tabs
• Highlighting and underlining in qualifying copyrighted materials
• Printed RCW 19.28 and WAC 296-46B placed in a three-ring binder
• A compliant silent, nonprinting, nonprogrammable calculator

Current rules prohibit or restrict:

• Sticky notes
• Removable or repositionable tabs
• Handwritten notes in references
• Unauthorized blank or loose paper
• Noncompliant programmed calculators

Open book works best when you already know the subject and use the book to confirm the detail. If every question starts with a completely fresh search, the exam becomes four hours of competitive page turning.

How Retesting Works

Washington requires at least 70 percent on each exam section. If you fail a section, you can retest only the section you failed during the active exam period.

The current L&I exam page states that candidates must wait two weeks after failing a section before retesting. After three failures of a section, the waiting period increases to three months.

Candidates have one year from the first exam attempt to pass all required sections. If the year expires before all sections are passed, the candidate must retake the entire examination under the applicable rules.

Out-of-State, Military, and Reciprocity Paths

Not every candidate reaches the 01 exam through a Washington in-state apprenticeship. Washington maintains separate rules for qualifying out-of-state experience, equivalent apprenticeships, military electrical experience, and reciprocity.

Out-of-state candidates may qualify through an equivalent apprenticeship, certain qualifying out-of-state journey-level licenses, or documented experience that meets Washington's rules. Washington can require licensing-board verification, employer records, payroll documentation, detailed work categories, supervision information, and proof of lawful experience.

Military electrical experience can also receive consideration under Washington rules, although the amount and type of credit depend on the experience.

Washington currently has a reciprocal agreement with Oregon for certain qualifying General Journey Level electricians. Reciprocity depends on how the Oregon or Washington license was obtained, including apprenticeship and examination history.

Renewing a Washington 01 General Electrician Certificate

Washington electrician certificates renew every 3 years and expire on the certificate holder's birthday.

Current active-renewal requirements include 24 hours of approved continuing education:

• 8 hours of currently adopted NEC code update
• 4 hours of RCW/WAC review
• 12 additional hours of approved continuing education

Depending on the date of initial certification and the electrician's birthday, the first certificate period can be shorter than a full three years. After that, the regular cycle is three years.

Keep continuing education current before the birthday deadline. Code update classes are much easier to enjoy when they are education instead of a rescue mission.

A Practical Washington 01 Study Plan

1. Confirm your eligibility first. Make sure your apprenticeship or alternate path is actually approved for the 01 exam.
2. Study the exam blueprint. Put the most time into Wiring Methods, Grounding & Bonding, and Overcurrent Protection.
3. Practice service, feeder, and conductor calculations. Do the math, do not only read examples.
4. Review motors, transformers, and generators. Focus on sizing, protection, disconnecting, and grounding.
5. Rotate through special occupancies and equipment. Learn where unusual installations live in the NEC.
6. Work theory every week. Build speed with Ohm's law, power, voltage drop, single-phase, and three-phase calculations.
7. Study RCW and WAC separately. Washington Codes has its own exam section and passing score.
8. Practice open-book navigation. Identify the subject and likely reference before searching.
9. Take timed practice sessions. Train for 60 technical questions in three hours and 17 Washington questions in one hour.
10. Review every miss by cause. Separate code-navigation problems from math mistakes, theory gaps, and rushed reading.

Prepare for Broad Journey-Level Responsibility

The Washington 01 certificate is valuable because it is broad. It is also demanding for exactly the same reason. A General Journey Level Electrician needs to move comfortably from residential services to commercial feeders, motors, transformers, hazardous locations, health-care rules, emergency systems, generators, communication systems, and Washington licensing requirements.

That breadth should shape your study plan. Do not prepare as if the exam is only a bigger version of residential wiring. Use your apprenticeship experience, but connect it to the code articles, calculations, and state rules that control work beyond your most familiar job sites.

Frequently Asked Questions

Conclusion

The Washington 01 General Journey Level Electrician certificate is the state's broad journey-level credential, and the pathway reflects the responsibility that comes with that broad scope. A certified 01 electrician can work across residential, commercial, industrial, and many specialized electrical installations instead of being limited to one specialty classification.

The biggest current licensing change is the apprenticeship requirement. Washington's temporary transition allowance for certain experienced trainees ended July 1, 2026. For a new in-state candidate today, the normal path is completion of an approved 8,000-hour electrical construction apprenticeship. At least 4,000 of those hours must be new industrial or commercial installations. Qualifying specialty experience can count toward part of the total, but the broad 01 credential still requires broad training.

Once L&I approves the candidate for examination, the current 01 test has two sections. NEC & Theory contains about 60 questions and allows three hours. Washington Codes contains about 17 questions and allows one hour. Each section requires a score of at least 70 percent. Unlike the General Master and General Administrator exams, there is no separate Major Load Calculations section at the electrician level.

The technical blueprint tells you where to spend time. Wiring Methods is the largest category. Grounding & Bonding and Overcurrent Protection follow closely. Services, conductors, motors, transformers, generators, special occupancies, special equipment, emergency systems, communications, and general electrical theory round out the exam.

The breadth can look intimidating, but the open-book format rewards organized preparation. Learn the structure of the NEC instead of trying to memorize the entire book. Practice recognizing the topic, identifying the likely article, finding the controlling section or table, and applying the rule. That skill is more valuable than remembering one answer from one practice question.

Washington law deserves the same treatment. RCW Chapter 19.28 and WAC Chapter 296-46B cover certification, apprenticeship and trainee rules, electrical contractors, permits, inspections, supervision, enforcement, continuing education, and state amendments. The Washington Codes section is separate, so candidates should practice using these references as seriously as the NEC.

The current exam still identifies the 2020 NEC. Use the edition listed in the live PSI bulletin even if a newer code book is sitting on the store shelf. The exam is open book, but handwritten notes, sticky notes, removable tabs, and other noncompliant materials can be rejected at the testing center.

After certification, the learning does not stop. Washington electrician certificates renew every three years and currently require 24 hours of approved continuing education, including code update and Washington law-and-rule review. That continuing education matters because an 01 electrician works across such a wide range of systems.

The best way to prepare is to connect your apprenticeship experience with the exact code and Washington rules behind the work. When field knowledge, code navigation, theory, calculations, and state-law understanding all support each other, the exam becomes a test of skills you have actually built rather than a four-hour search through a stack of books.

Key Takeaways

• As of September 2026, the normal in-state 01 route is completion of an approved 8,000-hour electrical construction apprenticeship because the temporary non-apprenticeship allowance ended July 1, 2026.
• At least 4,000 hours must be new industrial or commercial electrical installations, and no more than 4,000 hours can come from qualifying 4,000-hour specialties.
• The current 01 exam is approximately 60 NEC & Theory questions in 3 hours plus 17 Washington Codes questions in 1 hour.
• Washington requires at least 70 percent on each section, and the current PSI bulletin still identifies the 2020 NEC.
• The 01 certificate renews every three years and currently requires 24 hours of approved continuing education.

Plain-Language Summary

Washington's General Journey Level Electrician certificate is called the 01 certificate. It is the broad electrician credential in Washington. A certified 01 electrician can perform all types of electrical and telecommunications installations allowed by state law instead of being limited to one specialty.

The qualification path changed. Washington used to have a temporary option that allowed certain experienced trainees to finish qualifying without joining a registered apprenticeship. That temporary option ended July 1, 2026. For a new in-state candidate now, the normal route is an approved 8,000-hour electrical construction apprenticeship.

At least 4,000 of those hours must be new industrial or commercial electrical installations. Washington can allow up to 4,000 hours from qualifying 4,000-hour specialties to count toward the total. Experience from shorter 2,000-hour specialties does not count toward the 01 requirement.

After you complete the qualifying pathway, you apply to Washington Labor & Industries. L&I reviews your eligibility. Once approved, you schedule the correct 01 General Journey Level Electrician exam through PSI.

The current exam has two parts. NEC & Theory has about 60 questions and gives you three hours. Washington Codes has about 17 questions and gives you one hour. You need at least 70 percent on both sections.

Wiring Methods is the biggest technical category. Grounding and Bonding and Overcurrent Protection are also major areas. You should study services, feeders, conductors, motors, transformers, generators, hazardous locations, special occupancies, special equipment, emergency systems, communications, and general electrical theory.

The Washington Codes section comes mainly from RCW Chapter 19.28 and WAC Chapter 296-46B. These references cover electrician certification, apprenticeship and trainee rules, contractors, permits, inspections, supervision, examination rules, enforcement, continuing education, and Washington-specific electrical requirements.

The exam is open book. Washington's current PSI bulletin still identifies the 2020 National Electrical Code. Permanent tabs, highlighting, and underlining may be allowed in qualifying references. Sticky notes, removable tabs, and handwritten notes are not allowed.

If you fail one section, you can normally retest that section during your active one-year exam period. Washington currently requires a two-week wait after a failed section and a three-month wait after three failures. If the one-year period ends before you pass everything, you can be required to retake the full exam.

Once certified, your 01 certificate renews every three years and expires on your birthday. Current renewal rules require 24 hours of approved continuing education, including 8 hours of code update and 4 hours of RCW/WAC review.
