Open Book Test

The NASCLA Accredited Trade Examination for Electrical Contractors is an open-book test using approved references allowed by the testing provider. Candidates are responsible for bringing their own reference materials to the examination center. References may be highlighted, underlined, annotated, and indexed before the examination session begins.

During the exam, candidates may not write, highlight, underline, or index inside the reference books. Any markings, notes, highlighting, underlining, or indexing must be completed before the exam begins. Candidates should arrive with their references already organized and ready to use.

Reference materials may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary removable tabs, including Post-it style tabs or other removable markers, are not allowed and must be removed before the exam begins.

Candidates may use a silent, nonprinting, non-programmable calculator in the examination center. Loose papers and additional attached papers are not allowed with approved references. Downloaded references may be brought into the testing center when they are properly bound, such as spiral bound or placed in a binder after being hole-punched.

Open-book electrical exams reward preparation and organization. The books can help during the exam, but candidates still need electrical knowledge, code familiarity, calculation practice, safety awareness, and the ability to identify which reference applies to the question. Highlighting and tabs help candidates move through the references with purpose instead of searching without a plan.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. Candidates pursuing the C-11 or CR-11 Electrical classification should begin by reviewing the classification scope, confirming the exam path they want to use, and preparing for the required trade examination. For this package, the exam path is the NASCLA Accredited Trade Examination for Electrical Contractors.

The person who satisfies the examination requirement is commonly the qualifying party for the license. The qualifying party is connected to the contractor license application and is responsible for demonstrating knowledge in the classification. Applicants must still follow the Arizona Registrar of Contractors licensing process for application forms, business information, bonding, financial responsibility items, and other required licensing materials.

A practical preparation path begins with gathering the approved references, reviewing the NASCLA electrical content outline, and building a study schedule around the major subject areas. Candidates should divide study time across NEC navigation, electrical theory, wiring methods, wiring protection, general equipment, special occupancies, energy standards, OSHA safety, NFPA 70E electrical safety, project management, and contractor business practices.

After preparing, candidates schedule and complete the required examination through the testing provider. Passing the NASCLA electrical exam is an important licensing step, but passing the exam does not automatically issue a contractor license. The license application must still be submitted to the Arizona Registrar of Contractors and reviewed according to state licensing requirements.

State Requirements

The Arizona C-11 and CR-11 electrical scope includes installation, alteration, and repair of wiring, related electrical material, and equipment used in generating, transmitting, or utilizing electrical energy less than 600 volts. The scope includes overhead electrical wiring on public rights-of-way for signs and street decorations, underground electrical distribution systems of less than 600 volts serving private properties, and wiring in or on buildings less than 600 volts.

Arizona C-11 and CR-11 Electrical applicants may choose between the NASCLA Accredited Trade Examination for Electrical Contractors and the Arizona ROC Electrical Commercial exam. This package is organized for the NASCLA exam option and uses the reference list effective for that examination path.

The NASCLA exam is not a contractor license by itself. It is a trade examination that may support licensing applications in participating jurisdictions that accept the NASCLA electrical exam. Candidates still need to follow each licensing agency’s application requirements, including Arizona’s contractor licensing process when applying in Arizona.

Test Information and Study Materials

The NASCLA electrical exam requires a balanced study plan because the test covers code navigation, calculations, safety, project management, and practical electrical contracting knowledge. Candidates should begin with the content outline, then connect each subject area to the references most likely to support that topic.

NEC preparation should be a major part of the study schedule. Candidates should practice navigating chapters, articles, definitions, tables, annex material where applicable, and index entries. Code questions may require fast movement between general requirements, wiring methods, overcurrent protection, grounding and bonding, equipment rules, and special occupancies.

Electrical theory preparation should include Ohm’s law, power formulas, series and parallel circuits, transformers, motors, conductor properties, voltage drop, grounding concepts, and load relationships. Theory study helps candidates understand why the NEC applies the way it does, especially on calculation-based and application-based questions.

Safety preparation should include both OSHA and NFPA 70E. Candidates should review construction jobsite hazards, workplace safety standards, electrical safe work practices, personal protective equipment, energized work concepts, shock hazards, arc flash awareness, ladders, tools, and hazard recognition.

Project management and business preparation should include planning, scheduling, communication, risk, contracts, documentation, project administration, and contractor responsibilities. Energy standard preparation should focus on commercial energy requirements connected to lighting, electrical systems, controls, and building performance.
