Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. A candidate pursuing the Arizona Electrical Commercial Contractor (C-11) license should begin by confirming that the C-11 commercial classification matches the work the business intends to perform. The classification should align with commercial electrical systems, wiring methods, services, feeders, branch circuits, equipment, grounding, bonding, fire alarm systems, photovoltaic work, and related electrical construction.

After confirming the proper classification, the candidate should review the required examination path. Arizona contractor licensing may include a trade examination, statutes and rules requirements, qualifying party requirements, experience requirements, bonding, business entity information, and application documentation. This exam book package supports preparation for the technical trade exam portion of the licensing process.

The qualifying party is responsible for demonstrating the knowledge and experience required for the license classification. Candidates should prepare for the C-11 trade exam using the approved references and supplemental study materials included in this package. A practical preparation routine should include reviewing OSHA, studying the 2017 National Electrical Code, learning NFPA 72 fire alarm and signaling system requirements, practicing electrical calculations, and reviewing photovoltaic system fundamentals.

After preparation, the candidate can schedule the required examination through the proper testing process and complete the exam according to current procedures. Once examination requirements are completed, the applicant continues through the Arizona contractor license application process. This may include submitting the correct application, naming the qualifying party, satisfying experience requirements, obtaining any required bond, and meeting other state licensing requirements that apply to the classification and business structure.

This exam book package does not replace the state license application. It supports the study portion of the licensing path by giving candidates the references needed to prepare for commercial electrical work, electrical code requirements, fire alarm systems, OSHA safety, photovoltaic systems, calculations, wiring methods, grounding, bonding, equipment, services, feeders, and branch circuits connected to the Arizona C-11 classification.

State Requirements

The Arizona Registrar of Contractors issues residential, commercial, and dual contractor license classifications. The C-11 classification is a commercial electrical classification.
