Open Book Test

The NASCLA Accredited Trade Examination for Electrical Contractors is an open-book examination. Candidates may use approved reference materials during testing according to current NASCLA and PSI examination-center rules.

An open-book examination still demands significant preparation. The reference collection contains thousands of pages of technical information, and candidates have a fixed amount of testing time. Searching through unfamiliar books can consume valuable minutes, especially on questions involving several related Code provisions or calculations.

National Electrical Code navigation should be practiced repeatedly. Candidates should become comfortable with the NEC index, Article 100 definitions, chapter organization, tables, exceptions, notes, and cross-references. Frequently encountered topics can include services, feeders, branch circuits, conductor ampacity, overcurrent protection, grounding and bonding, raceways, cables, boxes, motors, transformers, and equipment.

Supporting references deserve the same attention. OSHA Part 1926 addresses construction safety. NFPA 70E focuses on electrical workplace safety. Electrical theory references support calculations and fundamental concepts. Project-management references address planning, coordination, estimating, risk, and professional project responsibilities. Energy-efficiency standards add another specialized area of study.

Reference preparation should follow current testing rules. Candidates should make sure any highlighting, underlining, indexing, or tabbing complies with the requirements in effect for their scheduled examination. Study sessions should use the books in a configuration similar to what will be permitted at the testing center.

State Requirements

Electrical contracting in North Carolina is regulated by the North Carolina State Board of Examiners of Electrical Contractors. The Board issues Limited, Intermediate, Unlimited, and Special Restricted electrical contracting licenses and establishes the experience and qualification standards associated with each classification.

North Carolina accepts the NASCLA Electrical Contractor/Master Electrician examination for multiple license classifications. Applicants who have passed this NASCLA examination may apply for Special Restricted, Limited, Intermediate, or Unlimited electrical contracting licensure, provided they meet the requirements associated with the desired classification.

North Carolina requires at least 3,000 hours of qualifying experience for the Limited classification. At least 2,000 of those hours must consist of primary experience. Primary experience generally involves direct electrical installation work governed by the National Electrical Code.

The Intermediate classification requires at least 5,750 hours of qualifying experience, including at least 5,000 hours of primary experience. The Intermediate license allows the licensee to engage in electrical contracting projects within the project-value limitations established for that classification.

The Unlimited classification requires at least 9,000 hours of qualifying experience, including at least 8,000 hours of primary experience. Unlimited applicants must also provide statements from two persons knowledgeable about the applicant's electrical experience that address the applicant's ability to supervise and direct electrical wiring or installation work performed by an electrical contracting business.

The Unlimited classification allows a licensed electrical contracting business to undertake electrical contracting projects without a project-value limitation. The Limited and Intermediate classifications operate under the project limits established by North Carolina law and Board rules.

North Carolina requires an electrical contracting licensee to have at least one listed qualified individual who is regularly employed and has responsibility and authority to supervise and direct the electrical contracting work performed under the license. Businesses with separate places of business must comply with the Board's requirements for qualified individuals.

Intermediate and Unlimited license applicants must also satisfy North Carolina's bonding ability or financial qualification requirements. These requirements are part of license activation and are separate from passing the NASCLA trade examination.

A passing NASCLA examination result is not itself a North Carolina electrical contracting license. The NASCLA examination can satisfy the accepted trade-examination component, but applicants must still send the required transcript and complete the North Carolina licensing process.

Test Information and Study Materials

A strong preparation plan uses the books actively rather than saving them for examination day. Begin by learning which reference is most useful for each major subject. This can help reduce time spent searching in the wrong book when working through practice questions.

Spend significant time with the 2023 National Electrical Code. Practice finding requirements involving services, feeders, branch circuits, conductor sizing, overcurrent protection, grounding and bonding, raceways, cables, boxes, motors, transformers, and electrical equipment. Pay attention to definitions, exceptions, tables, and cross-referenced provisions.

Electrical theory should be practiced through calculations. Use the theory references to reinforce circuit relationships and calculation methods. A consistent process can include identifying the information given, determining what must be solved, selecting the appropriate formula, maintaining correct units, completing the calculation, and then checking for applicable Code requirements.

Safety preparation should involve both OSHA and NFPA 70E. Learn the function and organization of each reference so you can determine which source is appropriate when a question addresses jobsite safety, electrical hazards, or workplace electrical practices.

Project design, estimating, and management also deserve focused preparation. Electrical contractors work within larger construction projects involving planning, communication, scheduling, coordination, risk management, documentation, and business responsibilities. These areas extend examination preparation beyond installation skills alone.

Timed reference-navigation exercises can help bring the material together. Choose practice questions from different subjects, identify the appropriate reference, locate the controlling information, and measure the time required. Repeated practice can reveal which books or topics need additional study.
