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 candidate 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, and related trade knowledge.

The exam may include questions based on listed reference materials, trade knowledge, and general industry practices.

This package includes the 2018 International Plumbing Code, 2018 International Fuel Gas Code, and 2018 International Mechanical Code, along with OSHA, NFPA sprinkler standards, and Arizona wastewater provisions.

Students should be prepared for questions involving water supply systems, sanitary drainage, storm drainage, vents, fixtures, traps, interceptors, fuel gas piping, appliance venting, combustion air, mechanical equipment, sprinkler systems, on-site wastewater treatment provisions, excavation safety, and solar-related plumbing work. The reference list covers several technical areas, so candidates should study by topic and practice locating information in the correct book.

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 the allowed references to the examination center. Since this exam uses multiple code books, standards, and Arizona-specific provisions, book familiarity is a major part of exam readiness.

Open-book testing still requires serious preparation. Candidates must understand the subject matter, identify which reference applies to the question, locate the correct section, and read carefully. Many plumbing, fuel gas, mechanical, sprinkler, and wastewater questions depend on definitions, tables, exceptions, conditions, and exact code wording.

Students should prepare with the books included in this package and practice using them regularly. A strong routine includes reviewing a topic, answering practice questions, locating the supporting material in the references, and repeating weaker areas until the books become easier to use. The goal is to make the approved references familiar before exam day.

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 other 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 examination 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.

The Application Service included with this Ultimate package helps students stay organized while working through application-related steps. It can support preparation of application information and help candidates better understand the licensing process. State approval, license issuance, and exam results are determined by the appropriate Arizona licensing and testing authorities.

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, and repeated reference practice. The approved book list includes plumbing, fuel gas, mechanical, sprinkler, wastewater, and OSHA references, so students should organize their study by topic rather than moving randomly from book to book.

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 solar-related preparation, students should use the 2018 International Mechanical Code along with plumbing and fuel gas references to understand connected systems, combustion air, venting, mechanical equipment, hydronic system awareness, boiler-related concepts, and solar plumbing integration. Solar-related plumbing work may involve piping, water heating, pool heating, circulation, controls, and system installation concepts.

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 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 OSHA safety, students should study 29 CFR Part 1926 for common construction hazards. Plumbing contractors may encounter excavation hazards, ladders, scaffolds, material handling, personal protective equipment, electrical hazards, and general jobsite safety responsibilities. OSHA questions often describe a work condition and require the candidate to identify the correct safety practice or rule.

The 1 year of course access included with this Ultimate package gives students time to review exam topics, practice reference navigation, and work through the approved books at a steady pace. The course helps turn the reference list into a more manageable study plan by guiding students through the types of material that matter for exam preparation.
