2026 Hawaii Master Electrician Exam Prep Study Package Includes Instructor-Led NEC Course (Based on the 2026 NEC)

Prepare for advanced electrical licensing and supervisory responsibilities in Hawaii with a comprehensive study package built around the 2026 National Electrical Code. This Hawaii Master Electrician Exam Prep Study Package combines NFPA 70, National Electrical Code, 2026 Edition, NEC tabs, flash cards, a Master Electrician Study Guide, a Calculations Study Guide, an online instructor-led NEC course, simulated practice exams, an NEC overview, and live and recorded instructional videos.

Hawaii does not use Master Electrician as the official title of its broad statewide supervisory electrician license. The comparable credential is the Supervising Electrician license, identified by the license code ES and regulated by the Hawaii Board of Electricians and Plumbers within the Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division.

A Hawaii Supervising Electrician is licensed to direct and supervise the performance of electrical work and may also personally perform electrical work. This makes the ES credential the Hawaii electrician classification most closely associated with the responsibilities commonly described as master-level electrical work.

This study package is based on the 2026 National Electrical Code and provides advanced electrical code instruction, calculations practice, reference-navigation training, electrical theory review, and structured exam preparation. Hawaii’s current PSI electrician examination bulletin identifies the 2020 National Electrical Code as the NEC reference provided for the Supervising Electrician examination. Candidates taking the current Hawaii exam should therefore also prepare with the 2020 NEC required by the official testing program.

The included 2026 NEC gives electricians a current-code learning platform covering services, feeders, branch circuits, grounding and bonding, conductors, overcurrent protection, raceways, motors, transformers, lighting, equipment, special occupancies, special conditions, and other advanced electrical subjects.

The included NEC tabs help students organize important articles, definitions, and tables while developing faster navigation habits. The Master Electrician Study Guide provides advanced electrical review, while the Calculations Study Guide focuses on electrical mathematics involving loads, conductor sizing, services, feeders, motors, transformers, voltage drop, raceway fill, box fill, and other practical applications.

Flash cards provide active-recall practice for formulas, definitions, terminology, and important electrical concepts. The online course adds instructor-led NEC education, simulated practice examinations, an organized NEC overview, live instructional videos, and recorded lessons that can be reviewed around a working electrician’s schedule.

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. Candidates must first apply to the Board of Electricians and Plumbers and receive examination approval before registering with PSI.

The current Supervising Electrician examination contains 70 scored questions and allows 180 minutes, or three hours, for completion. A minimum score of 70 percent is required to pass.

The examination may also include a small number of experimental questions that are not scored. These questions are used for future examination development and do not count toward the candidate’s final score.

General Electrical Knowledge accounts for six questions. Candidates should understand electrical theory, terminology, practical trade concepts, formulas, electrical power relationships, and general principles expected of an experienced supervising electrician.

Services, Feeders, and Branch Circuits account for 10 questions. Preparation should include service conductors, service equipment, feeder sizing, branch-circuit requirements, load calculations, disconnecting means, conductor ampacity, overcurrent protection, and electrical distribution requirements.

Grounding and Bonding account for another 10 questions. Candidates should understand grounding electrode systems, grounding electrode conductors, equipment grounding conductors, bonding jumpers, service bonding, separately derived systems, enclosures, raceways, and effective ground-fault current paths.

Conductors and Cables account for eight questions. Candidates should review conductor ampacity, insulation types, temperature limitations, correction factors, adjustment factors, conductor sizing, cable applications, terminations, and protection requirements.

Raceways and Boxes account for four questions. Preparation should include permitted raceway types, conduit fill, support requirements, box sizing, conductor installation, cabinets, fittings, enclosures, and physical protection.

Special Occupancies, Conditions, and Equipment account for four questions. These subjects require candidates to understand how specialized NEC rules modify or supplement the general electrical requirements that apply to ordinary installations.

Electrical Power accounts for six questions and Motors account for another six. Master-level preparation should include voltage, current, resistance, power, single-phase and three-phase calculations, motor conductors, overload protection, short-circuit and ground-fault protection, disconnects, controllers, and motor-related NEC tables.

Low Voltage and Communication Circuits account for two questions, Lighting for four, Illuminated Signs for two, Safety Information for four, and Overcurrent Protection for four.

The simulated practice exams included with this package help candidates combine electrical theory, calculations, code navigation, and trade knowledge while identifying areas that require additional review before the official examination.

Open Book Test

The Hawaii Supervising Electrician examination is an open-book examination. The examination center provides the National Electrical Code reference used during the test.

The current PSI examination bulletin identifies NFPA 70, National Electrical Code, 2020 Edition, as the examination reference provided at the testing center. Candidates are not expected to bring their personal NEC book into the testing room for the current Supervising Electrician examination.

This package includes the 2026 NEC and uses it throughout the instructor-led course. Candidates can use the 2026 edition to develop current-code knowledge and navigation skills while also studying the 2020 NEC required by the current Hawaii exam program.

The testing center provides the authorized NEC reference, and other electrical reference materials identified in the bulletin are not permitted in the examination room. Candidates should therefore focus on understanding how to navigate the NEC efficiently rather than relying on multiple personal reference books during the official test.

The included NEC tabs are valuable during preparation even though a personal tabbed NEC is not used during the current Hawaii examination. Repeated practice with tabs can help candidates build a mental map of the code and become familiar with the general location of frequently tested subjects.

Students should practice locating services, feeders, branch circuits, grounding and bonding, conductor tables, raceways, boxes, motors, overcurrent protection, lighting, special occupancies, equipment, definitions, and general-use provisions.

Use the NEC table of contents, index, Article 100 definitions, chapter organization, article numbering, conductor tables, grounding tables, motor tables, exceptions, informational notes, and cross-references during regular study sessions.

An open-book exam still requires strong preparation. With 70 scored questions and three hours available, candidates should recognize the electrical subject quickly and then move directly toward the relevant article or table instead of searching through the NEC without a plan.

The Master Electrician Study Guide, Calculations Study Guide, flash cards, simulated practice exams, live videos, recorded videos, and course materials are designed for preparation and should not be treated as authorized exam-room references unless the official testing program specifically permits them.

Licensing Steps

Begin by obtaining the experience required for Hawaii Supervising Electrician examination eligibility. The standard ES qualification requires four years of experience as a licensed Journey Worker Electrician or equivalent experience accepted by the Board.

For applicants using equivalent experience obtained outside Hawaii, the Board evaluates whether the applicant held a journey-worker or supervising-level electrician license and whether the licensing requirements in the other jurisdiction were substantially equivalent to Hawaii’s requirements.

Maintain accurate documentation of electrical employment, license history, supervisors, and the type of work performed. Hawaii requires experience verification from the licensed electricians under whom qualifying training or experience was obtained.

Submit the required Supervising Electrician application and supporting experience documentation to the Hawaii Board of Electricians and Plumbers.

The Board reviews the application and determines whether the candidate meets the qualification requirements in effect at the time of application. Hawaii does not reciprocate electrician licenses with other jurisdictions, so out-of-state applicants must follow Hawaii’s application and qualification process.

After receiving Board approval, register for the Supervising Electrician examination through PSI. Examination eligibility remains valid for the period established by the current testing program.

Prepare systematically for the exam by starting with the NEC overview. Use the included 2026 NEC and tabs to learn the organization of the code, then apply those navigation skills to the NEC edition used by the official Hawaii examination.

Work through the Master Electrician Study Guide for advanced review. Use the Calculations Study Guide regularly to strengthen services, feeders, loads, conductors, motors, transformers, voltage drop, raceway fill, box fill, and electrical theory.

Use flash cards for active recall of formulas, definitions, terminology, grounding concepts, conductor requirements, motor rules, and other information that benefits from repetition.

Attend live instructor-led NEC sessions and use recorded videos to revisit difficult technical subjects. Complete simulated practice exams using the three-hour Hawaii testing period as a pacing target.

After passing the examination and completing all licensing requirements, obtain the Hawaii Supervising Electrician license before representing yourself as holding that credential or performing work that requires it.

Hawaii electrician licensing does not by itself authorize an individual or business to contract directly with customers for electrical work. Electrical contracting is regulated separately under Hawaii contractor licensing laws.

State Requirements

Hawaii licenses electricians statewide through the Board of Electricians and Plumbers within the Professional and Vocational Licensing Division of the Department of Commerce and Consumer Affairs.

Hawaii uses the title Supervising Electrician rather than Master Electrician for the broad supervisory electrician classification. The license code for this credential is ES.

A Supervising Electrician is authorized to direct and supervise electrical work and may also perform electrical work within the scope of the license.

To qualify for the Supervising Electrician examination, an applicant must document four years of experience as a licensed Journey Worker Electrician or equivalent experience accepted by the Board.

Hawaii does not have electrician license reciprocity with other jurisdictions. Applicants with out-of-state experience must submit documentation and demonstrate qualifications that satisfy Hawaii’s licensing standards.

Journey Worker Electrician applicants are subject to separate experience and educational requirements. Hawaii currently requires Journey Worker Electrician applicants to document five years and at least 10,000 hours of qualifying residential or commercial wiring experience together with 240 hours of approved electrical academic coursework.

The Hawaii Supervising Electrician examination is administered by PSI and currently consists of 70 scored questions with a three-hour time limit and a 70 percent passing requirement.

The current testing bulletin identifies the 2020 NEC as the electrical code reference provided for the Supervising Electrician examination. This 2026 NEC study package therefore provides newer-code education while candidates also prepare with the code edition used by the official examination.

Active Hawaii electrician licenses are renewed on a three-year cycle. Electrician licenses were due for renewal by June 30, 2026, with the next regular renewal period ending June 30, 2029.

Active Supervising Electricians are subject to Hawaii’s continuing-competency requirements for license renewal. Hawaii uses approved National Electrical Code update training as part of the continuing-competency process.

Licensed electricians remain responsible for complying with Hawaii licensing law, adopted electrical standards, supervision requirements, safety requirements, permits, inspections, and the limits of their license classification.
