2023 Hawaii Master Electrician Exam Prep Study Package Includes Instructor-Led NEC Course Based on the 2023 NEC

Build advanced electrical knowledge with a complete Hawaii exam preparation package centered on the 2023 National Electrical Code. This package combines NFPA 70, NEC tabs, electrical flash cards, a master electrician study guide, an electrical calculations study guide, simulated practice exams, and an online instructor-led NEC course with live and recorded video instruction.

Hawaii does not issue an electrical license formally titled “Master Electrician.” The comparable advanced statewide credential is the Supervising Electrician license. A Hawaii Supervising Electrician is authorized to direct and supervise the performance of electrical work and to perform electrical work within the scope established by state law.

This Hawaii Master Electrician Exam Prep Study Package uses “master electrician” to describe the advanced level of electrical preparation included in the program. It is designed for experienced electricians who want to strengthen their understanding of electrical systems, calculations, National Electrical Code requirements, and the knowledge areas associated with Hawaii’s Supervising Electrician examination.

Preparing for an advanced electrical examination requires more than field experience. Candidates must interpret technical questions, recognize the electrical subject being tested, understand how code provisions connect, perform calculations accurately, and manage time effectively. The package provides an organized study structure that brings these skills together.

The included instructor-led NEC course explains how the 2023 National Electrical Code is organized and applied. Students can follow the instruction with the included NEC book, use permanent-style tabs to organize major articles, and reinforce important information with flash cards, study guides, calculation exercises, and simulated practice exams.

Live instruction gives students a structured learning environment, while recorded videos allow candidates to pause lessons, repeat difficult explanations, and revisit calculation demonstrations. This combination supports working electricians who need flexibility when preparing around projects, employment schedules, and personal responsibilities.

Hawaii’s Supervising Electrician examination is open book, but the National Electrical Code reference is provided by the examination center. Personal books, tabs, notes, study guides, and outside reference materials are not permitted in the examination room. The included 2023 NEC and tabs are therefore intended for course participation, home study, and the development of strong code-navigation skills before test day.

Exam Details

The Hawaii Supervising Electrician examination is administered by PSI for the Hawaii Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division, and the Board of Electricians and Plumbers. Applicants must receive approval from the Board before registering for the examination.

The Supervising Electrician examination contains 70 questions. Candidates receive 180 minutes to complete the exam and must earn a minimum score of 70 percent to pass. A small number of experimental questions may also be included. Experimental questions are not scored, and the time used to answer them does not count against the published examination time.

The published examination content outline includes the following subjects:

• General electrical knowledge
• Services, feeders, and branch circuits
• Grounding and bonding
• Conductors and cables
• Raceways and boxes
• Special occupancies, conditions, and equipment
• Electrical power
• Motors
• Low-voltage and communication circuits
• Lighting
• Illuminated signs
• Safety information
• Overcurrent protection

Services, feeders, branch circuits, grounding and bonding, and conductors represent substantial portions of the examination. Candidates should also prepare for motors, electrical power, raceways, special installations, lighting, communications, safety, and overcurrent-protection questions.

The examination is computer administered. One question appears on the screen at a time, and candidates may return to earlier questions while testing time remains. An introductory computer tutorial is provided before the examination begins.

PSI provides an online calculator. Candidates may also bring a permitted nonprogrammable calculator that is silent, battery operated, does not print, and does not contain an alphabetic keyboard. Scratch paper and a pencil are supplied at the testing center and must be returned after the examination.

Open Book Test

The Hawaii Supervising Electrician examination is an open-book test. The approved National Electrical Code reference is supplied by the examination center. Candidates may use the provided code book while answering examination questions.

Personal reference books are not permitted. Candidates may not bring their own NEC, tabs, handwritten notes, flash cards, study guides, calculation books, notebooks, or outside reading materials into the examination room.

The testing center currently identifies the 2020 National Electrical Code as the supplied examination reference. The course included with this package is based on the 2023 NEC, so candidates should recognize that the course edition and examination-center reference edition are not the same. The package remains useful for developing advanced code knowledge, electrical calculations, code structure awareness, and exam-style problem-solving skills.

Differences between NEC editions can affect article language, definitions, tables, requirements, and exceptions. Candidates should prepare specifically for the edition supplied at the examination center in addition to completing the broader 2023 NEC course included with this package.

Open-book testing does not remove the need for preparation. With 70 questions and 180 minutes, candidates have an average of slightly more than two and one-half minutes per question. Some questions can be answered quickly, while calculations and multi-section code research may require additional time.

A strong testing method begins with identifying the electrical subject before using the code book. Candidates should determine whether the question involves a service, feeder, conductor, raceway, grounding method, motor, overcurrent device, special occupancy, lighting system, or another installation. This approach narrows the search and reduces time spent in unrelated sections.

The included tabs help students organize their personal 2023 NEC during course participation and home study. Because PSI supplies an unmarked examination reference, students should also practice locating information in a clean code book without relying entirely on personal tabs.

Licensing Steps

1. Identify the appropriate Hawaii license classification. Review the electrical license categories regulated by the Board of Electricians and Plumbers and confirm that the Supervising Electrician credential matches your professional goal.
2. Review the application requirements. Obtain the current electrician application and instructions from the Hawaii Professional and Vocational Licensing Division.
3. Complete the license application. Provide the personal, employment, education, and licensing information requested by the Board.
4. Document electrical experience. Submit the required electrician experience-verification forms and supporting records in the format established by the state.
5. Provide academic-coursework documentation. Submit evidence of the approved academic coursework required for the selected electrical license classification.
6. Submit license verifications when applicable. Applicants who hold or previously held licenses in another jurisdiction may need to provide official verification.
7. Receive Board approval. Candidates may not register for the examination until the Board approves the application and issues examination eligibility.
8. Schedule the examination with PSI. After receiving eligibility, create a PSI account, select the Supervising Electrician examination, and choose an available testing appointment.
9. Prepare for the examination. Review the complete content outline, practice calculations, study the applicable NEC edition, and complete simulated practice exams.
10. Take the examination. Arrive with acceptable identification and comply with all PSI security, calculator, and testing procedures.
11. Complete license issuance. Follow the instructions provided by the Board after passing and satisfy any remaining licensing requirements.

Examination eligibility is valid for two years. Eligible candidates may retest during that period according to PSI’s scheduling and payment procedures. Passing the examination does not independently create an active Hawaii license; the applicant must complete the full state licensing process.

State Requirements

Hawaii regulates electricians through the Board of Electricians and Plumbers within the Department of Commerce and Consumer Affairs. Electrical license classifications include journey worker, industrial, specialty, maintenance, supervising, supervising industrial, and supervising specialty credentials.

The Supervising Electrician license is the classification most closely associated with broad master-level responsibility. The license allows the holder to direct and supervise the performance of electrical work and to perform electrical work within the authorized scope.

Applicants must satisfy the experience and academic-coursework requirements established for the selected classification. The Board reviews the submitted application, employment records, education documentation, and license history to determine whether the applicant qualifies for examination.

Experience documentation should accurately describe the electrical work performed, employment dates, supervision, types of systems, and level of responsibility. Applicants should ensure that employer information and license records are complete and consistent.

Academic coursework must meet the standards approved by the Board. General training, manufacturer instruction, informal education, or unrelated college classes should not be assumed to satisfy the required electrical coursework unless accepted by the state.

Hawaii electrician licenses renew on a three-year cycle. Active licensees are subject to the continuing-competency requirements established for the applicable renewal period. License holders should maintain their records and complete required education before the renewal deadline.

The Board determines whether an applicant meets the qualifications for examination and licensure. Purchasing a study package, completing a course, or passing simulated practice exams does not replace the state’s experience, education, application, examination, and licensing requirements.
