Candidates should prepare for electrical theory, personal and jobsite safety, project design and management, grounding and bonding, circuit protection, wiring methods, equipment for general use, special electrical systems, test equipment, and energy-efficiency concepts. Because these topics are spread across several technical references, familiarity with the books is an important part of preparation.

The Idaho NASCLA Master Electrical Contractor - Highlighted and Tabbed Book Package gives candidates a structured collection for studying those subjects. Use the books to reinforce electrical theory, practice National Electrical Code research, complete calculations, review OSHA and NFPA 70E safety material, and develop a repeatable process for finding information under timed conditions.

Exam Details

The NASCLA Accredited Trade Examination for Electrical Contractors is designed for Electrical Contractors, Master Electricians, and Unlimited Electricians. It is part of the NASCLA Accredited Electrical Examination Program, which provides standardized trade examinations accepted by participating licensing agencies.

• Examination: NASCLA Accredited Trade Examination for Electrical Contractors
• Classification: Electrical Contractors / Master Electricians / Unlimited Electricians
• Scored Questions: 100
• Minimum Passing Score: 70
• Time Allowed: 270 minutes
• Exam Type: Open book

The current examination outline includes electrical theory, personal and jobsite safety, project design, estimating and management, grounding and bonding, special systems and special equipment installations, tools and test equipment, circuit protection and installation, wiring methods and practices, equipment for general use, and energy-related material.

The examination is intended to evaluate practical electrical knowledge and the ability to apply technical information. Candidates should be prepared to move between direct trade knowledge and reference research. Some questions may require an electrical calculation, while others may require locating a Code provision, safety requirement, project-management concept, or specialized technical standard.

The 270-minute testing period makes pacing and navigation important. Candidates should practice identifying the subject of a question before opening a book. Determining whether the question involves Code requirements, theory, OSHA, NFPA 70E, project management, or another topic can reduce unnecessary searches and help candidates use their reference materials more effectively.

Open Book Test

The NASCLA Electrical Contractor/Master Electrician examination is an open-book examination. Approved reference materials may be used during testing in accordance with current examination rules.

Open-book testing does not eliminate the need for technical preparation. Electrical references can contain hundreds or thousands of pages of information, and candidates who are unfamiliar with their books may lose valuable time searching. Highlighting and permanent indexing can support more efficient navigation by making major subjects and important provisions easier to identify.

NASCLA permits approved examination references to be highlighted, underlined, and permanently indexed. Temporary markers and removable notes are not permitted. Candidates should use their highlighted and tabbed books during regular study sessions so the organization becomes familiar before the examination.

The 2023 National Electrical Code should receive extensive navigation practice. Candidates should become comfortable locating branch-circuit requirements, feeder and service provisions, conductor ampacity, grounding and bonding requirements, overcurrent protection, wiring methods, raceways, cables, motors, transformers, equipment, special occupancies, and special systems.

Safety references should also be incorporated into preparation. OSHA 29 CFR Part 1926 focuses on construction safety requirements, while NFPA 70E addresses electrical safety in the workplace. Understanding the purpose and organization of each reference can make it easier to determine where to look when a safety question appears.

Electrical theory and calculation references should be used actively rather than simply read. Practice solving voltage, current, resistance, power, motor, transformer, and circuit problems. For each question, determine what information is provided, identify the formula or Code requirement that applies, and work through the solution in a consistent sequence.

Timed lookup exercises can help candidates take full advantage of the highlighted and tabbed format. Select a practice question, identify the subject, choose the appropriate reference, navigate to the relevant section, and locate the supporting information. Repeating this process helps build familiarity with the entire reference set.

7. Take and pass the applicable examination. Candidates must satisfy the examination requirement associated with the Idaho license they are seeking.
8. Submit the Idaho license application. After satisfying the applicable qualification and examination requirements, applicants complete the licensing process through the Idaho Division of Occupational and Professional Licenses.
9. Designate the required supervising electrician for contractor licensing. An Idaho electrical contractor must designate an appropriately licensed supervising electrician responsible for the contractor's electrical activities.
10. Maintain the license and supervision requirements. Licensed contractors and supervising electricians must continue to comply with Idaho's electrical licensing and practice requirements.

State Requirements

Electrical licensing in Idaho is regulated by the Idaho Electrical Board through the Division of Occupational and Professional Licenses. Idaho licenses Electrical Contractors, Master Electricians, Journeyman Electricians, and additional electrical specialties under its electrical licensing laws and rules.

Idaho is a participating jurisdiction in the NASCLA Accredited Electrical Examination Program. The state accepts the NASCLA Electrical Contractor/Master Electrician examination and the NASCLA Journeyman Electrician examination.

The individual Master Electrician license and the Electrical Contractor license serve different purposes. A Master Electrician is an individual professional credential, while an Electrical Contractor license authorizes the contracting business to perform electrical contracting work within the scope allowed by the license and supervising electrician.

For the Idaho Master Electrician experience pathway, an applicant must have held an Electrical Journeyman license for at least four years. Idaho also provides a reciprocity pathway when the applicant satisfies the applicable license-verification conditions, including proof of qualifying journeyman licensure and an active master license.

Idaho electrical contractor applicants must pass an examination designated by the Electrical Board and submit the applicable application. Each electrical contractor must designate one supervising electrician who is responsible for the activities performed under the contractor license.

The supervising electrician must hold an Idaho electrical credential appropriate for the scope of work being performed. A master electrician, journeyman electrician, residential electrician, or limited electrical installer may serve as a supervising electrician when the contractor's work falls within that person's licensed scope of practice.

Idaho rules also specify that the contractor's allowable scope of electrical work follows the scope of its licensed supervising employee. This makes the supervising electrician an important part of the contractor licensing structure and distinguishes the business license from the individual electrical credential.

Passing the NASCLA examination does not automatically create an Idaho Master Electrician or Electrical Contractor license. Candidates must still apply through the Division of Occupational and Professional Licenses and satisfy the experience, supervision, application, and other requirements associated with the credential they are pursuing.

Idaho electrical examinations are administered through PSI. After achieving the required passing result, applicants proceed with the appropriate Idaho licensing application through the Division of Occupational and Professional Licenses.

Test Information and Study Materials

Highlighted and tabbed references are most useful when candidates work with them throughout their preparation. Use the tabs during regular Code review, electrical calculations, safety research, and practice questions so the location of major subjects becomes familiar.

Start with the 2023 National Electrical Code and practice navigating services, feeders, branch circuits, conductor sizing, overcurrent protection, grounding and bonding, wiring methods, motors, transformers, equipment, and special installations. Learn to use both the index and the Code's internal cross-references.

Electrical theory should be reinforced with active problem solving. Practice voltage, current, resistance, power, motors, transformers, and related calculations. Develop a consistent method for determining what the question asks, selecting the correct formula, completing the calculation, and checking whether a Code rule changes the result.

Use OSHA Part 1926 and NFPA 70E for focused safety review. Learn which reference applies to construction safety and which addresses workplace electrical safety. This distinction can make reference searches more efficient.

Project-management and contractor-business references should also remain part of the study schedule. Electrical contracting involves more than installation knowledge, and candidates should become familiar with planning, coordination, risk, communication, estimating concepts, and professional project responsibilities.

Finally, practice under timed conditions. Work through sample questions using the actual highlighted and tabbed references. Track how quickly you identify the subject, select the correct book, reach the relevant section, and confirm the answer. This approach helps combine technical understanding with practical open-book navigation.
