Arizona Electrical Commercial Contractor (C-11) Exam Prep - Live Virtual + Self Study Training

Prepare for the Arizona Electrical Commercial Contractor (C-11) examination with a flexible training program that combines a complete online self-study course, recorded instruction, and live virtual classes covering the electrical codes, construction safety regulations, fire alarm requirements, calculations, and photovoltaic subjects associated with this contractor license exam.

The Arizona C-11 Electrical classification applies to commercial electrical contracting work within the scope established by the Arizona Registrar of Contractors. Candidates preparing for this classification need a strong working knowledge of commercial electrical systems, National Electrical Code requirements, grounding and bonding, conductors, raceways, services, feeders, branch circuits, motors, overcurrent protection, fire alarm systems, jobsite safety, special occupancies, and photovoltaic installations.

This Arizona C-11 electrical contractor exam prep program provides several ways to review the tested material. The full online course gives you an organized self-paced study path. Recorded instruction allows you to pause explanations, repeat calculations, and revisit difficult code-navigation lessons. Live virtual classes add scheduled instructor-led training organized around the books and technical references used for the license examination.

The training 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 commercial electrical installations, OSHA construction safety, National Electrical Code requirements, fire alarm systems, electrical calculations, and photovoltaic installation practices, you only need to attend the sessions covering the books included on your specific exam. The complete online course and recordings provide additional opportunities to study outside the scheduled live sessions.

Live Class Schedule

The live training schedule is organized around the books and technical references used on the exam.

Because this is a seminar-style training program that covers electrical code requirements, commercial wiring systems, OSHA safety regulations, fire alarms, photovoltaic systems, conductor sizing, grounding and bonding, motors, raceways, overcurrent protection, services, feeders, and branch circuits, you only need to attend the sessions covering the books included on your specific exam.

The live classes work together with the full online course and recorded instruction. You can begin with self-paced lessons, attend the applicable live sessions for guided review, and return to the recordings when you need additional practice with a calculation, code article, safety rule, fire alarm topic, or photovoltaic concept.

Licensing Steps

1. Select the C-11 classification. Review the Arizona Registrar of Contractors classification scope and confirm that the commercial electrical license matches the work your business plans to perform.
2. Identify the qualifying party. The qualifying party must satisfy the examination and experience requirements associated with the classification.
3. Complete the Arizona Statutes and Rules requirement. The qualifying party must complete the applicable Arizona statutes and rules training or qualify for an authorized waiver.
4. Select the electrical trade examination. C-11 applicants may choose the Arizona C-11 Electrical Commercial examination or the NASCLA Accredited Trade Examination for Electrical Contractors.
5. Prepare with the correct materials. Use the examination outline and reference list that apply to the selected test.
6. Register with PSI. Schedule the applicable electrical trade exam through PSI and select an available testing appointment.
7. Pass the required examination process. Complete the required trade and statutes and rules requirements before submitting the contractor license application.
8. Submit background checks. Complete the approved background-check process for each person required to be listed in the license application.
9. Obtain the contractor bond. Secure the bond required for the commercial contractor license and the anticipated volume of work.
10. Submit the license application. Provide the completed application, qualifying-party information, identification, examination records, background-check information, bond, fees, and supporting documents to the Arizona Registrar of Contractors.

Arizona requires applicants to complete all applicable examination requirements before the contractor license application can be accepted for processing. Examination results must be submitted within the period established by the Arizona Registrar of Contractors.

State Requirements

The C-11 Electrical license is a commercial specialty contractor classification. It applies to the installation, alteration, and repair of wiring, electrical materials, and equipment used in generating, transmitting, or using electrical energy below 600 volts.

The scope includes qualifying overhead electrical wiring, underground electrical distribution systems serving private properties, outside electrical construction, and wiring in or on commercial buildings within the limitations of the classification.

The C-11 classification is intended for commercial electrical contracting. Contractors seeking authority to perform both commercial and residential electrical work should review the CR-11 dual classification rather than relying on the commercial-only C-11 license.

The business must designate a qualifying party who meets the experience and examination requirements for the classification. The Arizona Registrar of Contractors evaluates the qualifying party’s experience based on the documentation submitted with the application.

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

Test Information and Study Materials

Begin by organizing the examination outline into code, safety, fire alarm, electrical calculation, and photovoltaic categories. This helps you determine which reference should be used when a question appears.

Spend substantial study time navigating the 2017 National Electrical Code. Learn the structure of the chapters, the Article 100 definitions, the index, major tables, and the articles associated with services, feeders, branch circuits, grounding, conductors, raceways, motors, overcurrent protection, special occupancies, and solar installations.

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

Review OSHA 29 CFR Part 1926 for construction safety subjects involving electrical hazards, employee protection, fall prevention, ladders, scaffolds, excavation, tools, and personal protective equipment.

Photovoltaics account for an important part of the examination outline. Study solar modules, arrays, direct-current circuits, inverters, batteries, disconnects, grounding, system sizing, installation, commissioning, and safety. Use the photovoltaic study references together with the applicable NEC requirements.

Practice using the approved books under timed conditions. Permanent tabs and organized highlighting can support faster navigation, but familiarity with the reference structure is more important than simply adding a large number of tabs.

During practice sessions, identify the subject first, select the correct reference, locate the relevant section, and complete the question before checking the answer. This develops the same sequence of skills required during an open-book examination.
