Safety and project-management subjects expand preparation beyond installation rules and reflect the broader responsibilities of experienced electrical professionals.

Open Book Test

The NASCLA Accredited Trade Examination for Electrical Contractors is an open-book examination. Approved reference materials may be used during testing in accordance with the current NASCLA and examination-center rules.

Open-book testing does not eliminate the need to study. The reference collection contains a large amount of technical information, and candidates have a fixed amount of testing time. Searching every question from the beginning of an unfamiliar book can quickly consume valuable minutes.

National Electrical Code navigation should become part of regular preparation. Candidates should practice using the NEC index, definitions, chapter organization, articles, tables, exceptions, and cross-references. Important areas can include branch circuits, feeders, services, conductor ampacity, overcurrent protection, grounding and bonding, raceways, cables, motors, transformers, electrical equipment, special occupancies, and specialty systems.

Supporting references should also be used throughout preparation. OSHA Part 1926 addresses construction safety requirements. NFPA 70E addresses electrical workplace safety practices. Electrical theory references provide formulas and principles, while project-management resources address planning, coordination, risk, communication, and project responsibilities.

NASCLA examination rules permit approved references to be highlighted, underlined, and permanently indexed. References must otherwise comply with the current testing requirements and may not contain unapproved loose or attached material. Candidates should prepare their books according to the rules that apply to their scheduled examination.

Licensing Steps

1. Determine the Kentucky electrical credential you need. Kentucky separately licenses master electricians, electricians, and electrical contractors through the Department of Housing, Buildings and Construction.

5. Prepare with the examination references. Study the NEC, electrical theory, OSHA requirements, NFPA 70E, project-management concepts, energy-efficiency material, and supporting electrical references.
6. Take and pass the NASCLA examination. Candidates must achieve the applicable passing score on the NASCLA Electrical Contractor examination.
7. Submit examination documentation to Kentucky. Kentucky applicants using NASCLA are required to provide their passing score information and submit an electronic NASCLA transcript through the National Examination Database.
8. Complete the Kentucky license application. Submit the applicable application and required experience documentation for the master electrician or other electrical credential being pursued.
9. Complete electrical contractor requirements when applicable. Applicants operating as electrical contractors must satisfy Kentucky's separate contractor licensing requirements, including the required relationship with a Kentucky licensed master electrician.

State Requirements

Electrical licensing in Kentucky is administered by the Department of Housing, Buildings and Construction. Kentucky regulates electrical contractors, master electricians, and electricians as separate license categories.

Kentucky accepts the NASCLA Electrical Contractor/Master Electrician examination for applicable electrical licensure. The Department announced the NASCLA electrical examination option as part of its transition to examinations aligned with the 2023 National Electrical Code. Kentucky's mandatory enforcement of the 2023 NEC began January 1, 2025, and electrical examinations transitioned fully to the 2023 NEC beginning January 1, 2026.

A Kentucky master electrician applicant must document 16,000 hours of verifiable electrical-trade experience completed since the applicant's sixteenth birthday. Kentucky law permits qualifying education and training to substitute for portions of the experience requirement.

Completion of an acceptable electrical training course may substitute for 4,000 hours of required experience. Two years of teaching electrical technology or a related field at an accredited college or university may also substitute for 4,000 hours.

Completion of an associate degree or diploma program in electrical technology or a related field through the Kentucky Community and Technical College System or another accredited college or university may substitute for 6,000 hours of required electrical-trade experience.

Applicants must also satisfy the applicable examination requirement. Kentucky requires electrical-license applicants to pass an examination administered by an approved examination provider. Under Kentucky's current regulations, a passing examination score remains valid for three years.

An electrical contractor license is different from a master electrician license. Kentucky requires an applicant for an electrical contractor license to identify the master electrician affiliated with the contractor. Kentucky law also requires an electrical contractor to comply with applicable insurance requirements before the contractor license can be issued.

Passing the NASCLA examination does not automatically create a Kentucky master electrician or electrical contractor license. NASCLA provides an accepted examination credential. Kentucky continues to evaluate the applicant's experience, documentation, affiliated master electrician requirements when applicable, and other state licensing conditions.

Test Information and Study Materials

The strongest way to use an exam book package is to work with the references throughout your study period. Candidates should learn the purpose and organization of each book rather than waiting until the examination to decide where information may be located.

Begin with the 2023 National Electrical Code. Review services, feeders, branch circuits, conductor sizing, ampacity, overcurrent protection, grounding and bonding, raceways, cables, boxes, motors, transformers, and equipment requirements. Practice finding the controlling Code sections and related tables instead of relying exclusively on memorized article numbers.

Electrical theory should be studied through active problem solving. Use the electrical theory references to reinforce voltage, current, resistance, power, circuit relationships, motors, transformers, and other fundamentals. Develop a consistent process for identifying known values, selecting a formula, completing the calculation, and checking whether an NEC requirement affects the final result.

Safety preparation should include both OSHA Part 1926 and NFPA 70E. Learn the role of each reference and how its information is organized. This makes it easier to recognize whether a question is addressing general construction safety or electrical workplace safety.

Project-management study should include planning, communication, coordination, risk, scheduling, documentation, and other responsibilities associated with managing electrical construction work. The project-management and NASCLA contractor references broaden preparation beyond technical installation subjects.

Energy-efficiency material should also be included in the study schedule. Become familiar with the terminology and organization of the ASHRAE/IES standard so relevant information can be located more efficiently during practice and testing.

Timed navigation exercises help bring these skills together. Select practice questions from different subjects, identify the most appropriate reference, locate the supporting information, complete any necessary calculation, and track the time required. Repeated practice can reveal which books and subject areas need additional attention.
