Open Book Test

The Arizona C-11 Electrical trade examination is an open-book test using approved reference materials. Candidates must bring the permitted books and follow the testing provider’s current requirements regarding editions, highlighting, annotations, permanent tabs, attachments, calculators, and book inspection.

An open-book examination still requires strong electrical knowledge. Candidates must identify the installation condition, determine the calculation or code subject involved, select the correct reference, locate the applicable requirement, and apply it within the available testing time.

All books are highlighted and Tabbed. Highlighting draws attention to important National Electrical Code provisions, fire-alarm requirements, photovoltaic topics, electrical formulas, field tables, and OSHA safety standards. Permanent tabs support faster movement among major articles and commonly researched subjects.

The references should be used throughout the course rather than opened for the first time on examination day. Repeated navigation practice helps candidates become familiar with article locations, indexes, definitions, tables, exceptions, diagrams, formulas, and permanent tab positions.

Questions involving services, feeders, branch circuits, wiring methods, conductor ampacity, raceway fill, grounding, bonding, motors, transformers, equipment, special occupancies, and photovoltaic installations may require the National Electrical Code.

Questions involving fire-alarm control units, initiating devices, notification appliances, circuits, power supplies, supervision, testing, or maintenance may require NFPA 72.

Ugly’s Electrical References supports faster review of formulas, conductor information, motor data, conversions, voltage drop, and practical electrical calculations. Photovoltaic Systems supports broader solar-electric preparation involving system components, design, installation, commissioning, and troubleshooting.

Questions involving electrical hazards, temporary wiring, ladders, tools, fall protection, personal protective equipment, material handling, or construction-site safety may require OSHA 29 CFR Part 1926.

Candidates should bring only references authorized for the examination they schedule. Loose pages, temporary tabs, removable notes, electronic materials, and unauthorized attachments are not permitted under standard testing rules.

State Requirements

The C-11 classification is an Arizona commercial specialty contractor license for qualifying electrical work. It does not provide residential electrical contracting authority.

The proposed qualifying party must demonstrate the experience, knowledge, and skills needed to supervise or perform commercial electrical work. Experience records may describe services, feeders, branch circuits, raceways, panels, motors, transformers, lighting, controls, fire alarms, photovoltaic systems, commercial projects, estimating, and field supervision.

The qualifying party must remain associated with the applicant business in the capacity recognized by the Arizona Registrar of Contractors. Examination results, experience records, and business information should remain consistent throughout the licensing process.

The legal business entity applying for the license must be properly established and identified. The company name, ownership information, qualifying-party records, EIN documentation, contractor bond, and application should remain consistent.

Persons listed on an Arizona contractor license application must complete the applicable criminal background-check process and provide the identifying and disclosure information required for state review.

A commercial specialty contractor license bond is required. The applicable bond amount depends on the anticipated gross volume of commercial work.

Because C-11 is a commercial-only classification, the residential financial-protection requirements associated with Arizona residential and dual licenses do not apply.

Passing the examination is only one part of the licensing process. The business may not operate as a licensed C-11 contractor until the Arizona Registrar of Contractors approves the application and issues the active license.

After licensing, the contractor must remain within the authorized C-11 scope, maintain the required bond, renew the license, and keep qualifying-party and business information current.
