2026 Hawaii Master Electrician Exam Prep Study Guides & Code Book Ultimate Combo (Based on the 2026 NEC)

The 2026 Hawaii Master Electrician Exam Prep Study Guides & Code Book Ultimate Combo is designed for electrical professionals preparing for advanced Hawaii electrician licensing with a complete study package built around NEC study, electrical calculations, trade knowledge, open-book exam preparation, flash card review, online practice, and application service. This Ultimate Combo gives candidates an organized way to study for Hawaii’s supervising-level electrician exam preparation while using materials based on the 2026 National Electrical Code.

Hawaii does not use “Master Electrician” as the official electrical license title in the same way many other states do. Hawaii licenses individual electricians through the Board of Electricians and Plumbers under the Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division. The supervising-level electrician license is the Supervising Electrician license. A Supervising Electrician is licensed to direct and supervise the performance of electrical work and to perform electrical work.

This package is built for candidates who want master-level preparation depth for Hawaii supervising electrician exam readiness. The exam requires knowledge of electrical systems, services, feeders, branch circuits, grounding and bonding, conductors, cables, raceways, boxes, special occupancies, electrical power, motors, low voltage systems, lighting, illuminated signs, safety, overcurrent protection, and NEC-based code application. Candidates also need to understand how to work through a timed open-book exam efficiently.

The included study materials support a complete preparation routine. The 2026 Hawaii Master Electrician Study Guide helps organize trade and code review. The 2026 Electrician Calculations Study Guide supports focused practice with electrical math and formula work. The National Electrical Code 2026 Paperback with Tabs helps candidates build NEC familiarity and reference-navigation habits. The 2026 Master Electrician Flash Cards help reinforce important terms, formulas, and concepts through repetition. The 2026 Master Electrician Exam Questions and Study Guide - Online Test Success Kit adds question-based online review and exam-style practice.

For many experienced electricians, licensing exam preparation is different from field work. The exam requires careful reading, reference familiarity, time management, and the ability to answer questions based on code language rather than habit alone. This Ultimate Combo gives candidates a structured way to study, review, practice, and build confidence before exam day.

Exam Details

Hawaii electrician licensing is handled by the Hawaii Board of Electricians and Plumbers through the Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division. PSI administers the Hawaii electrician examination program. Candidates are not allowed to register for an exam until the Board approves the application and sends the candidate a letter of approval.

The Hawaii Supervising Electrician examination includes 70 questions, requires a minimum passing score of 70%, and allows 180 minutes of testing time. The examination may also include a small number of experimental questions that do not count toward the candidate’s score. The candidate’s score is displayed on screen at the end of the examination, and a score report is provided at the test site.

The Supervising Electrician content outline includes General Electrical Knowledge, Service, 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, and Overcurrent Protection.

Hawaii also licenses other electrical classifications, including Journey Worker Electrician, Journey Worker Specialty Electrician, Maintenance Electrician, Journey Worker Industrial Electrician, Supervising Industrial Electrician, and Supervising Specialty Electrician. Candidates should select the examination that matches the license classification they are applying for.

For candidates pursuing broader business authority, Hawaii electrical contracting is handled separately through the contractor licensing structure. A supervising electrician license is an individual license. Operating an electrical contracting business may require a separate contractor license classification and additional business-related licensing steps.

Open Book Test

The Hawaii Supervising Electrician exam is an open-book exam. The examination center provides the reference material used during the exam. The PSI candidate bulletin lists the National Electrical Code, 2020 edition, as the reference material provided by the examination center for the Supervising Electrician exam.

Candidates may not bring unauthorized reference materials into the examination room. The bulletin identifies several materials as not allowed in the examination center, including other listed electrical references and safety publications. Candidates should follow all PSI test-center rules for identification, calculators, personal items, scratch paper, and examination conduct.

Open book does not mean the exam is easy. Candidates still need to know how to read questions carefully, recognize the subject being tested, locate information efficiently, and apply the correct rule. Because the test center provides the reference book, candidates should focus their preparation on understanding NEC organization rather than relying on personal notes or custom exam-room materials.

The National Electrical Code 2026 Paperback with Tabs included in this Ultimate Combo is a study tool for building code familiarity before exam day. Studying with a tabbed NEC helps candidates become more comfortable with article structure, definitions, tables, wiring methods, service rules, feeder requirements, branch circuit rules, grounding and bonding, overcurrent protection, motors, lighting, and special installation requirements. Even when the exam center provides the reference edition used for testing, disciplined NEC study helps candidates work more efficiently with code-based questions.

Licensing Steps

Hawaii Supervising Electrician candidates begin by reviewing the licensing requirements established by the Hawaii Board of Electricians and Plumbers. Candidates must apply through the Board and receive approval before scheduling the examination with PSI. The Board’s application process requires the candidate to submit the proper application form, fee, and required supporting documentation.

To be eligible for the Supervising Electrician examination, Hawaii law requires the applicant to have been registered with the Board as a journey worker electrician for at least four years or to have equivalent experience in the trade. Candidates should document experience carefully and follow the Board’s instructions for application materials and verification.

After the Board approves the candidate, the candidate receives eligibility information and may schedule the examination with PSI. The PSI examination fee is listed in the candidate bulletin, and the candidate’s eligibility period is valid for two years. Candidates should schedule the exam under the same legal name that appears on their government-issued identification.

On exam day, candidates should arrive at least 30 minutes before the appointment. Candidates must bring valid identification that matches the registered name. PSI provides an online calculator during the exam, and candidates who bring their own calculator must use one that meets PSI’s calculator rules. Scratch paper and a pencil are provided by the test center and must be returned to the proctor at the end of the examination.

After passing the examination, candidates must complete any remaining licensing steps required by the Board. Candidates should keep copies of application forms, approval notices, score reports, and licensing correspondence for their records.

State Requirements

Hawaii requires individuals who perform or supervise electrical work to hold the appropriate license. A person who directs or supervises electrical work in the state is required to have a supervising electrician’s license. A person who performs electrical work is required to have a journey worker electrician’s license unless the person is working under a permitted exception and proper supervision.

Hawaii’s electrical licensing structure includes multiple electrician categories. The Supervising Electrician license is the supervising-level license for directing and supervising electrical work while also allowing the license holder to perform electrical work. Specialty and industrial classifications have separate license paths and separate examination outlines.

For the journey worker electrician path, Hawaii requires qualifying work experience and electrical academic coursework. The supervising electrician path builds on journey worker-level registration or equivalent experience. Candidates should follow the license classification that matches their work history and intended scope of work.

Electrical contracting in Hawaii may require a separate contractor license. Individual electrician licensing through the Board of Electricians and Plumbers is not the same as business licensing for electrical contracting. Candidates who plan to operate a contracting business should review the contractor licensing requirements that apply to electrical contractors in Hawaii.

Calculations should be practiced consistently. Electrical calculation questions often require candidates to identify the correct method, choose the correct formula or table, convert units correctly, and check whether the answer is reasonable. Repeated practice helps reduce errors and improves confidence under exam time limits.

Code navigation should also be part of regular study. Candidates should practice using the NEC table of contents, index, definitions, article layout, tables, notes, exceptions, and cross-references. A candidate who knows how the NEC is organized can work more efficiently when answering open-book, code-based questions.

Flash cards are useful for shorter review sessions. Candidates can use them to reinforce terminology, formulas, safety concepts, code topics, and trade knowledge when they do not have time for a full practice exam.
