Open Book Test

The Arizona Electrical Residential Contractor (R-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 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 study references used for preparation include Ugly's Electrical References and Photovoltaic Systems, 3rd Edition, 2011. These references support preparation in electrical formulas, calculations, field reference information, photovoltaic system concepts, solar electric components, system layout awareness, and practical electrical review, but they are not listed here as exam-room-approved materials.

Open-book testing can help prepared candidates, but it does not replace study. The exam time limit does not allow unlimited searching. Candidates should know where to find OSHA safety requirements, NEC definitions, conductor rules, wiring method provisions, service requirements, grounding and bonding requirements, overcurrent protection rules, and NFPA 72 topics 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 residential electrical work, the relevant classification is R-11 Electrical Residential Contractor.

After selecting the correct classification, candidates should review the examination requirements tied to that license. The R-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 residential electrical systems, National Electrical Code requirements, OSHA safety, fire alarm and signaling awareness, wiring methods, services, feeders, branch circuits, grounding, bonding, overcurrent protection, calculations, devices, equipment, and photovoltaic system concepts. 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 R-11 electrical residential exam.

State Requirements

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

The R-11 classification is connected to residential electrical work within the allowed Arizona license scope. Electrical contractor work may include installation, alteration, and repair of wiring, electrical materials, and equipment used in residential electrical systems. Candidates should prepare for service equipment, feeders, branch circuits, wiring methods, devices, conductors, raceways, grounding and bonding, overcurrent protection, lighting, low-voltage awareness, and related residential electrical topics.

Residential electrical contractors should understand where their classification begins and ends. Work outside the license classification may require another properly licensed contractor. Candidates should also understand how electrical work may involve coordination with building, fire alarm, photovoltaic, mechanical, plumbing, and safety requirements.

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 R-11 electrical residential contractor classification.
