Prepare for the Arizona Electrical Residential / Commercial Contractor (CR-11) examination with a flexible training program that combines a complete online self-study course, recorded instruction, and live virtual classes covering the electrical code books, safety regulations, fire alarm requirements, and photovoltaic references associated with this license exam.

The Arizona CR-11 classification is a dual electrical contractor classification that combines residential and commercial electrical work within the applicable scope established by the Arizona Registrar of Contractors. Candidates preparing for this license need a broad working knowledge of electrical systems, National Electrical Code requirements, construction safety, fire alarm systems, photovoltaic installations, electrical calculations, wiring methods, services, feeders, branch circuits, grounding, bonding, conductors, raceways, equipment, and special occupancies.

This Arizona CR-11 electrical contractor exam prep program gives you multiple ways to study. The full online course provides an organized self-paced path through the major examination subjects. Recorded classes let you pause difficult explanations, repeat calculations, and revisit book-navigation lessons. Live virtual classes provide instructor-led training organized around the books and technical references connected to the examination.

The course covers the following references:

• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
• NFPA 70 - National Electrical Code, 2017 Edition
• NFPA 72 National Fire Alarm and Signaling Code, 2016 Edition
• Ugly's Electrical References
• Photovoltaic Systems, 3rd Edition, 2011
• The Easy Guide to Solar Electric Part II Installation Manual

Because this is a seminar-style training program that covers electrical systems, OSHA construction safety, National Electrical Code requirements, fire alarm and signaling systems, calculations, solar-electric equipment, and photovoltaic installation practices, you only need to attend the sessions covering the books included on your specific exam. The online course and recordings provide additional flexibility for reviewing topics outside the scheduled live sessions.

Preparation should include repeated practice identifying the subject, choosing the correct reference, locating the applicable section, and applying the information efficiently.

Open Book Test

The Arizona C-11/CR-11 Electrical Commercial examination is an open-book test with specific restrictions on which references may enter the examination area.

The following references are identified as approved exam-room references for this examination:

• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
• NFPA 70 - National Electrical Code, 2017 Edition
• NFPA 72 National Fire Alarm and Signaling Code, 2016 Edition

Candidates are responsible for bringing their approved references to the examination. Approved books may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or add indexing during the test.

Additional loose or attached papers are not permitted. References may be organized with permanent tabs that would tear the page if removed. Temporary tabs, removable sticky markers, and Post-it-style tabs are not allowed. Downloaded references may be accepted when properly bound, such as spiral-bound or placed in a binder after being hole-punched.

The remaining books listed with this course support preparation but are not identified as approved exam-room references:

• Ugly's Electrical References

State Requirements

The Arizona CR-11 classification is a dual residential and commercial electrical contractor classification. It combines the applicable scopes of the R-11 Residential Electrical and C-11 Commercial Electrical classifications.

The commercial electrical scope includes the installation, alteration, and repair of wiring, electrical material, and equipment used in generating, transmitting, or using electrical energy under 600 volts. It also includes applicable overhead and underground electrical construction and wiring in or on buildings under 600 volts.

The residential portion addresses electrical installation and repair within the residential scope recognized by the Arizona Registrar of Contractors. Candidates pursuing the dual CR-11 classification should be prepared to demonstrate experience and competence across both residential and commercial electrical work.

The qualifying party must meet the experience requirement assigned to the classification. The Arizona Registrar of Contractors evaluates experience based on the classification requirements and the documentation submitted with the application. Experience should reflect the practical trade knowledge and supervisory ability needed to perform or manage work within the CR-11 scope.

The licensing process may also require a business entity or sole-proprietor application, qualifying-party documentation, government-issued identification, background checks, a contractor bond, examination records, and the applicable licensing fees. The Arizona Registrar of Contractors determines whether an applicant and qualifying party satisfy all licensing requirements.

Test Information and Study Materials

Begin your preparation by dividing the content outline into code, safety, fire alarm, calculations, and photovoltaic categories. This makes it easier to identify which reference should be used when a question appears.

Spend significant time navigating the 2017 National Electrical Code. Learn the arrangement of the chapters, the Article 100 definitions, the index, major tables, and the articles connected to services, feeders, branch circuits, grounding, motors, overcurrent protection, special occupancies, and photovoltaic systems.

Use NFPA 72 to review fire alarm circuits, initiating devices, notification appliances, supervision, system performance, testing, and installation requirements. Practice separating NEC wiring questions from NFPA 72 fire alarm system questions so you can select the right book quickly.

Review OSHA 29 CFR Part 1926 for construction safety topics. Electrical contractors may encounter questions involving employee protection, fall hazards, ladders, scaffolds, excavation, tools, personal protective equipment, and safe work practices.

The photovoltaic references should be used to strengthen your understanding of solar modules, arrays, direct-current circuits, inverters, batteries, disconnects, grounding, system sizing, installation, commissioning, and safety. Photovoltaics account for ten questions on the examination outline, making solar preparation an important part of the study plan.

Practice under timed conditions with the approved books. Open-book success depends on knowing where information is located before the examination begins. Permanent tabs, organized highlighting, and repeated navigation practice can help reduce search time.
