Since the CR-11 classification covers both residential and commercial electrical work, candidates should prepare for a broad range of electrical contractor topics.

Open Book Test

The Arizona Electrical Residential/Commercial Contractor (CR-11) trade exam is an open-book exam. Candidates are responsible for bringing their own approved references to the examination center. The approved exam-room references include the Code of Federal Regulations - 29 CFR Part 1926 (OSHA), NFPA 70 - National Electrical Code, 2017 edition, and NFPA 72 National Fire Alarm and Signaling Code, 2016.

The references used for study but not allowed in the examination center include Ugly's Electrical References, Photovoltaic Systems, 3rd Edition, 2011, and The Easy Guide to Solar Electric Part II Installation Manual. These study references are useful for preparation because they support electrical formulas, quick reference tables, photovoltaic system fundamentals, and solar electric installation concepts, but they should not be brought into the exam room unless specifically listed as approved by the testing provider.

Open-book electrical testing rewards candidates who know how to use their references quickly. The National Electrical Code is especially important for the CR-11 exam, so candidates should become familiar with article structure, definitions, tables, wiring method rules, grounding and bonding provisions, overcurrent protection requirements, photovoltaic provisions, and equipment requirements before test day.

Reference materials may be highlighted, underlined, annotated, and indexed before the examination session. References may not be written in during the exam. Additional loose or attached papers are not permitted with approved references. Permanent tabs are allowed. Temporary removable tabs are not allowed. Candidates may use a silent, nonprinting, non-programmable calculator in the examination center.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Applicants should begin by selecting the correct license classification for the work they plan to perform. For electrical contracting work in both residential and commercial settings, the relevant classification is CR-11 Electrical Residential/Commercial.

After selecting the correct classification, candidates should review the examination requirements tied to that license. The CR-11 trade exam is one part of the licensing process. Contractor applicants may also need to complete the Arizona business management or statutes and rules requirement, application requirements, qualifying party requirements, bonding requirements, experience requirements, and other items required by the Arizona Registrar of Contractors.

A practical licensing plan separates exam preparation from application preparation. Exam preparation focuses on electrical code, wiring methods, services, feeders, branch circuits, grounding and bonding, conductors, raceways, boxes, overcurrent protection, motors, lighting, fire alarm systems, photovoltaics, low voltage, and OSHA safety. Application preparation focuses on state forms, business structure, qualifying party information, bond requirements, fees, and supporting documents.

Using online practice questions during the exam preparation phase gives structure to your study time. Questions help reveal which subjects are already familiar and which ones need more review. This makes it easier to use the 3-month access period productively and keeps preparation focused on the subjects most closely tied to the CR-11 exam outline.

State Requirements

The Arizona Registrar of Contractors issues contractor licenses by classification. Commercial classifications apply to commercial work, residential classifications apply to residential work, and dual classifications may apply when a contractor qualifies for both commercial and residential work. The CR-11 classification is the residential/commercial electrical contractor classification.

The CR-11 classification allows the scope of work permitted by the related residential and commercial electrical classifications. Electrical work may include installation, alteration, and repair of electrical systems, electrical wiring, electrical materials, and equipment used in generating, transmitting, or using electrical energy under the applicable license scope.

Electrical contractors should understand code compliance, jobsite safety, service equipment, branch circuits, feeders, grounding and bonding, wiring methods, raceways, boxes, conductors, lighting, motors, fire alarm systems, low-voltage systems, overcurrent protection, and photovoltaic systems. Work outside the license classification may require another properly licensed contractor.

Passing the trade exam is not the same as receiving a license. Applicants are responsible for meeting the full Arizona licensing requirements that apply to the classification, qualifying party, business entity, bond, application, and related state requirements. The trade exam supports the licensing process by testing technical knowledge connected to the electrical classification.

Test Information and Study Materials

The Arizona CR-11 exam requires preparation across electrical code, wiring methods, safety, fire alarm systems, photovoltaic systems, calculations, and practical electrical installation knowledge. Candidates should study the complete outline because the exam includes a broad mix of code-heavy topics and field-based electrical concepts.

General electrical knowledge preparation should include electrical theory, terminology, basic calculations, voltage, current, resistance, power, circuit behavior, conductor properties, and common field concepts. Service feeders and branch circuit preparation should include service equipment, load relationships, feeder rules, branch-circuit requirements, conductor sizing, disconnects, and code navigation within the National Electrical Code.

Grounding and bonding preparation should include grounding electrode systems, equipment grounding conductors, bonding jumpers, grounding conductor sizing, service bonding, separately derived systems, and related code rules. This is one of the most important study areas because grounding and bonding questions often require careful reading and accurate use of NEC tables.

Conductors and cables preparation should include conductor ampacity, insulation types, temperature ratings, adjustment and correction factors, cable assemblies, wiring limitations, and installation conditions. Raceways and boxes preparation should include conduit types, raceway fill, box sizing, pull boxes, junction boxes, supports, bending, and installation rules.

Special occupancies and equipment preparation should include code provisions for locations, equipment types, and installation conditions that require specific rules. Motors preparation should include motor circuits, disconnecting means, overload protection, branch-circuit protection, conductor sizing, and control concepts. Lighting and illuminated sign preparation should include lighting outlets, fixtures, controls, signs, and related wiring requirements.

Fire detection and alarm system preparation should include NFPA 72 terminology, initiating devices, notification appliances, fire alarm control equipment, circuits, placement concepts, inspection, testing, and system documentation awareness. Low-voltage preparation should include limited-energy systems, communication-related wiring concepts, and installation practices.

Photovoltaic preparation should include PV modules, arrays, conductors, disconnects, inverters, overcurrent protection, grounding and bonding, rapid shutdown concepts where applicable to the adopted code edition, system sizing, installation safety, and code-related photovoltaic requirements. Since photovoltaics account for a meaningful portion of the exam outline, candidates should give solar electric topics dedicated study time.

OSHA safety preparation should include electrical hazard awareness, personal protective equipment, ladder safety, fall hazards, tool safety, housekeeping, material handling, excavation awareness, and general jobsite hazard recognition. Electrical contractors work around energized systems, ladders, sharp tools, equipment, and active jobsites, making safety preparation important for both exam readiness and field performance.

Online practice questions help candidates move from passive reading to active recall. When you miss a question, use it as a signal for what to review next. Return to the related code article, safety section, fire alarm provision, photovoltaic topic, or electrical calculation reference, then practice again until the material becomes more familiar.

For open-book preparation, organize approved references before test day. Highlight important sections, use approved permanent tabs, and practice locating information while answering questions. The goal is not to search every answer from scratch. The goal is to understand the electrical topics well enough to answer efficiently and use the references when they are most helpful.
