Exam Details

The Hawaii Journey Worker Electrician examination is administered by PSI for the Hawaii Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division. Candidates are not allowed to register for the examination until the Board approves the application and sends an approval letter. The exam is computer-based and is scheduled through PSI after eligibility is issued.

The Hawaii Journey Worker Electrician exam contains 70 questions, allows 180 minutes of testing time, and lists a minimum passing score of 70%. The exam may also include a small number of unscored experimental questions used for examination development. These unscored questions do not count toward the final score.

The Journey Worker Electrician content outline includes 10 questions on General Electrical Knowledge, 10 questions on Service, Feeders, and Branch Circuits, 10 questions on Grounding and Bonding, 10 questions on Conductors and Cables, 6 questions on Raceways and Boxes, 6 questions on Special Occupancies, Conditions, and Equipment, 6 questions on Electrical Power, Motors, and Equipment for General Use, 4 questions on Low Voltage and Communication Circuits, 4 questions on Lighting, and 4 questions on Safety Information.

This exam outline shows why students should study across the full range of electrical topics. The largest areas include general electrical knowledge, services, feeders, branch circuits, grounding and bonding, conductors, and cables, but smaller categories still affect the final score. A candidate may need to identify a wiring rule, apply a grounding requirement, understand a service or feeder condition, answer a motor or equipment question, interpret a lighting requirement, or solve a calculation.

Because the test is timed, candidates should prepare for both speed and accuracy. Journey worker electrical exams reward students who can understand the question, identify the electrical subject, locate the proper code material, and apply the rule without spending too much time on one item. This combo supports that preparation by combining trade review, calculation practice, and NEC-based study.

Open Book Test

The Hawaii Journey Worker Electrician exam is an open book examination. The PSI candidate bulletin lists the examination as open book and states that the reference material is provided by the examination center. The listed reference material in the current bulletin is the National Electrical Code, 2020 edition.

This product is based on the 2026 NEC and includes the National Electrical Code 2026 Paperback for updated study, code navigation practice, and calculation-based preparation. Candidates should follow the current PSI and Hawaii Board testing instructions for the code edition and reference material used on exam day.

Open book testing still requires serious preparation. A code book is only helpful when the student knows how to use it. Candidates need to understand the subject being tested, locate the correct article or table, read the rule carefully, and apply the requirement under timed conditions. Slow reference navigation can make even familiar electrical topics difficult during an exam.

The National Electrical Code 2026 Paperback included in this combo gives students a physical code reference for building those skills during study. Students can practice locating common journeyman exam subjects such as conductor ampacity, services, feeders, branch circuits, grounding electrode systems, equipment grounding conductors, bonding jumpers, raceways, boxes, motors, electrical power, lighting, special occupancies, low-voltage circuits, communication circuits, and calculation-related provisions.

Open book study should include active NEC navigation. Students should use the index, article headings, definitions, tables, notes, and exceptions while answering practice-style questions. The goal is to become comfortable using the NEC as a working reference, not simply as a book to read from front to back. A student who regularly practices finding information is better prepared to manage time during a timed reference-based exam.

Licensing Steps

Hawaii Journey Worker Electrician candidates begin by meeting the experience and academic coursework requirements established by Hawaii law and the Board of Electricians and Plumbers. The applicant must document qualifying electrical experience and completion of the required electrical academic coursework before the Board can approve the application for examination.

The candidate submits the application for license to the Professional and Vocational Licensing Division with the required supporting documents. Experience verification must be completed and notarized by each licensed electrician under whom the applicant received experience or training. If experience was earned in a jurisdiction that does not require licensure as a journey worker, supervising, or master electrician and only requires a contractor license, the Board may accept a notarized experience verification form signed by the licensed contractor with verification of the contractor license.

The application must also include verification of completion of the required electrical academic coursework. Hawaii accepts documentation such as a diploma, certificate of completion, certificate of competence, certificate of achievement, transcript with completion information, a letter from the registrar of a University of Hawaii Community College, or a certificate of completion from an approved apprenticeship program when applicable.

After the Board reviews and approves the application, the candidate receives approval to register for the PSI examination. The candidate then schedules the exam through PSI, follows the computer-based testing procedures, and reports to the exam site with the required identification and testing documents.

After testing, the candidate receives score information according to PSI procedures. Passing the exam is part of the licensing process, but the license process is not complete until all Board requirements are satisfied. Candidates should follow the Professional and Vocational Licensing Division’s instructions for final licensing steps after examination.

A strong licensing plan begins early. Candidates should keep accurate employment records, obtain required notarized experience verification forms, complete the required academic coursework, review the exam outline, and build a study routine that includes trade review, calculation practice, and NEC navigation.

State Requirements

Hawaii requires a license before a person may act as a journey worker electrician, journey worker specialty electrician, supervising electrician, supervising specialty electrician, journey worker industrial electrician, supervising industrial electrician, or maintenance electrician. A person may not hold themselves out as an electrician without the proper license under Hawaii’s electrician licensing law.

For the Journey Worker Electrician license, Hawaii requires the applicant to be at least 18 years old and provide satisfactory evidence of experience in residential or commercial wiring of at least 5 years full-time or its equivalent, but not less than 10,000 hours, in the trade under the supervision of a journey worker or supervising electrician.

Hawaii also requires satisfactory completion of 240 hours of electrical academic coursework accepted by a University of Hawaii Community College offering an appropriate program of study. This academic coursework requirement applies to journey worker electrician applicants and must be documented as part of the application process.

The Journey Worker Electrician license is different from a contractor license. Hawaii’s requirements state that an electrician’s license does not allow a person to contract to perform electrical work. A contractor’s license is required for contracting activity. Students should understand the difference between being licensed as an individual electrician and operating as an electrical contractor.

Hawaii does not reciprocate with any jurisdiction for these electrician licenses. Applicants with out-of-state experience or licenses must still follow Hawaii’s application rules, submit required verification, and be qualified by the Board before testing.

Test Information and Study Materials

Hawaii Journey Worker Electrician preparation should include a broad review of electrical trade topics and code-based installation requirements. Important study areas include general electrical knowledge, services, feeders, branch circuits, grounding and bonding, conductors and cables, raceways and boxes, special occupancies, special conditions, equipment, electrical power, motors, equipment for general use, low-voltage circuits, communication circuits, lighting, safety, and calculations.

The 2026 Hawaii Journeyman Electrician Study Guide helps students organize these subjects into a practical study plan. Instead of studying random code sections without direction, candidates can work through one topic at a time and connect that subject to real electrical work. This approach helps students understand how exam questions may present jobsite conditions, code rules, and practical installation choices.

The 2026 Electrician Calculations Study Guide supports the math side of preparation. Electrical calculations often require several steps, and students should practice them repeatedly. Useful calculation areas include Ohm’s law, power formulas, conductor sizing, voltage drop concepts, box fill, raceway fill, load calculations, service and feeder calculations, branch circuit calculations, motor calculations, and overcurrent protection applications.

Calculation study should be active. Students should work problems by hand, write formulas clearly, identify known values, convert units where needed, and check whether the answer makes sense. Reading a solved example may introduce a concept, but repeated practice builds speed and confidence. This is especially important for timed electrical exams because calculation questions can take longer than direct code lookup questions.

The National Electrical Code 2026 Paperback should be used throughout the study process. Students should practice locating definitions, article sections, tables, notes, and exceptions. They should also learn how related code topics connect. A conductor question may involve ampacity, adjustment factors, terminal temperature limitations, overcurrent protection, and equipment rules. A grounding question may involve grounding electrodes, bonding jumpers, equipment grounding conductors, services, and fault-current paths.

A balanced study schedule may rotate between trade review, NEC navigation, and calculation practice. One session might focus on grounding and bonding. Another might focus on services, feeders, and branch circuits. Another might involve conductor sizing or box fill calculations. Another might involve locating raceway, lighting, or equipment rules in the NEC. This rotation helps candidates prepare across the full exam outline instead of becoming comfortable with only one subject area.

Students should also include timed practice. Since the Hawaii Journey Worker Electrician exam is timed and open book, pacing matters. Practice sessions should help candidates learn when to look up a rule, when to calculate, when to move forward, and how to manage the exam without spending too long on one question.
