Exam Details

The Arizona Plumbing, Including Solar Commercial Contractor (C-77) exam is part of the Arizona contractor licensing examination process. Arizona contractor trade exams are administered through PSI for the Arizona Registrar of Contractors. PSI provides examination information, content outlines, approved reference lists, exam rules, scheduling procedures, and testing requirements for Arizona contractor classifications.

The C-77 Plumbing, Including Solar commercial contractor exam includes 100 questions, allows 240 minutes of testing time, and requires a 70% minimum passing score. Candidates should prepare for commercial plumbing and solar-related topics, including plumbing code, fuel gas, mechanical systems, sprinkler references, wastewater provisions, OSHA safety, pipe trade calculations, hydronic heating, boiler concepts, utility locating, and related trade knowledge.

The C-77 exam may include questions based on reference material, trade knowledge, and general industry practices. Code-based questions are tied to the specific code editions listed for the examination, which is why candidates should study from the correct references. This package includes the 2018 International Plumbing Code, 2018 International Fuel Gas Code, 2018 International Mechanical Code, OSHA 29 CFR Part 1926, NFPA sprinkler standards, Arizona wastewater provisions, and additional trade references supplied for C-77 preparation.

Open Book Test

The Arizona C-77 Plumbing, Including Solar commercial contractor exam is an open-book trade exam using approved references. Candidates are responsible for bringing their allowed references to the examination center. Because the C-77 reference list includes multiple code books, standards, trade manuals, and Arizona-specific provisions, reference familiarity is one of the most important parts of preparation.

Open-book testing does not mean the answers are easy to find. Candidates must understand the subject matter, choose the right reference, locate the right section, and read carefully. Many plumbing, fuel gas, mechanical, sprinkler, and wastewater questions depend on definitions, tables, exceptions, notes, system conditions, and exact code wording.

Highlighted and tabbed books can help students practice more efficiently. Tabs help candidates move to important sections faster, while highlighting can help draw attention to commonly used rules, tables, definitions, and study areas. Students should still read the surrounding text, because exam questions often require more than a highlighted line or single table entry.

Reference materials may be highlighted, underlined, annotated, and indexed before the exam session under PSI rules. Candidates should not write in the references during the exam. Additional papers, whether loose or attached, are not allowed with approved references. Permanent tabs may be used, while temporary removable tabs are not allowed. Downloaded references must be bound before being brought into the testing center.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. A candidate pursuing the C-77 Plumbing, Including Solar Commercial Contractor classification should begin by confirming that the C-77 classification matches the commercial plumbing and solar plumbing work the business intends to perform.

The qualifying party is the individual responsible for meeting the examination requirements for the license classification. For many applicants, this includes passing the required trade exam and completing Arizona statutes and rules training when applicable. Applicants must also prepare business information, qualifying party information, and state application documents required by the Arizona Registrar of Contractors.

The general licensing path includes selecting the correct classification, preparing for the required examination, completing the exam process, gathering application materials, and submitting the contractor license application to the Arizona Registrar of Contractors. PSI administers the trade examination program, so candidates should follow PSI procedures for exam registration, scheduling, testing rules, and score reporting.

After exam requirements are completed, the licensing application is reviewed through the Arizona Registrar of Contractors. State approval is separate from exam preparation and depends on the applicant meeting all applicable requirements. This highlighted and tabbed book package supports exam preparation by providing an organized reference set for study and open-book practice.

State Requirements

The Arizona Registrar of Contractors issues contractor licenses for commercial, residential, and dual classifications. The C-77 Plumbing, Including Solar classification is a commercial classification for plumbing work, including solar, within the limits of the classification.

The C-77 classification covers installation, alteration, and repair of plumbing, including solar, when performed solely within property lines and not on public easements or rights-of-way except as permitted by the classification. It includes installation, alteration, and repair of piping, fixtures, and appliances related to water supply; venting and sanitary drainage systems; septic tanks and leaching lines; roof leaders; lawn sprinkler systems; water conditioning equipment; and piping and equipment for swimming pools.

The classification also allows sewer, gas, and water lines and connections from the structure to the nearest point of public supply or disposal to cross public or private easements or be installed within private easements, subject to the limits of the classification. Candidates should understand the state-defined scope before applying for the license and should make sure the classification fits the work their business intends to perform.

Arizona licensing requirements may include trade exam completion, qualifying party requirements, business entity information, application documents, financial or bonding-related requirements, and Arizona statutes and rules training when applicable. Requirements can vary based on the applicant’s business structure, qualifying party status, prior licensing history, and selected classification.

Test Information and Study Materials

Effective preparation for the Arizona C-77 Plumbing, Including Solar exam should include code study, safety review, solar system review, trade math, and repeated reference practice. The book list is extensive, so students should organize study by topic instead of trying to memorize each reference. A better approach is to learn which book answers which type of question and practice locating information quickly.

For plumbing code preparation, the 2018 International Plumbing Code is a major reference. Students should study water supply systems, sanitary drainage, storm drainage, venting, fixtures, traps, interceptors, cleanouts, materials, installation requirements, and inspection provisions. The IPC contains definitions, tables, and exceptions that require careful reading.

For fuel gas preparation, the 2018 International Fuel Gas Code should be reviewed closely. Students should focus on gas piping, sizing, appliance connections, combustion air, venting, shutoff valves, pressure testing, and installation requirements. Fuel gas questions often depend on system type, pressure, appliance condition, location, or table use.

For mechanical and hydronic preparation, students should use the 2018 International Mechanical Code, Modern Hydronic Heating, Boiler Operator’s Guide, and related pipe trade references. Preparation should include hydronic piping, boilers, pumps, controls, combustion air, venting, system operation, heating-system components, and mechanical equipment requirements.

For solar preparation, students should study solar water heating and solar pool heating concepts. Solar-related plumbing work can involve collectors, storage tanks, piping, pumps, controls, circulation, heat transfer, freeze protection, mounting considerations, and installation practices. Candidates should connect solar system knowledge with plumbing and mechanical system understanding.

For fire sprinkler preparation, students should review NFPA 13, NFPA 13D, and NFPA 13R. These standards support study for sprinkler system concepts, occupancy differences, system components, installation rules, water supply considerations, and fire protection requirements. Students should understand which sprinkler reference applies to which type of building or occupancy.

For wastewater and excavation-related preparation, candidates should review the Arizona wastewater provisions, Arizona 811 Blue Stake Brochure, and OSHA 29 CFR Part 1926. Plumbing work often involves underground systems, excavation, utility awareness, and site coordination. Understanding safe digging practices, excavation hazards, and jobsite safety responsibilities supports both exam preparation and professional work.

For trade math, students should use Mathematics for Plumbers and Pipefitters and IPT’s Pipe Trades Handbook to review measurements, conversions, offsets, slopes, pipe data, volume, area, pressure-related concepts, formulas, and practical jobsite calculations. Math questions are best prepared for through repeated practice, not quick review right before the exam.

Highlighted and tabbed books should be used actively during study. A productive routine is to answer a practice question, identify the subject, choose the correct reference, use the tabs to move to the likely section, and then read the highlighted material and surrounding text carefully. Students should not rely only on highlighted lines because exam questions may require definitions, table notes, exceptions, or related sections nearby.

Timed practice is important. The C-77 exam allows 240 minutes for 100 questions, so candidates should build a steady pace. Students should learn when to search a reference, when to rely on prepared knowledge, and when to move forward and return to a difficult question later.
