Exam Details

The Nevada C-2F Residential Wiring Contractor examination contains 50 questions. Candidates are allowed 2 hours to complete the examination and must answer 35 questions correctly to pass.

The examination content is divided into the following subject areas:

• General Electrical Knowledge: 9 questions
• Service, Feeders, and Branch Circuits: 10 questions
• Grounding and Bonding: 7 questions
• Conductors and Cables: 7 questions
• Overcurrent Protection: 4 questions
• Electrical Power: 2 questions
• Low Voltage: 2 questions
• Fire and Intrusion Detection and Alarm Systems: 2 questions

• Raceways and Enclosures: 3 questions

Service, Feeders, and Branch Circuits is the largest exam category with 10 questions. Candidates should understand residential service equipment, service conductors, disconnecting means, feeder arrangements, panelboards, branch circuits, and common residential load relationships.

General Electrical Knowledge accounts for 9 questions. This category supports the rest of the exam and can include basic electrical principles, terminology, circuit relationships, equipment, formulas, and practical electrical concepts.

Grounding and Bonding and Conductors and Cables each account for 7 questions. These two areas deserve substantial study because they represent a significant percentage of the overall examination.

Overcurrent Protection and Safety Information each account for 4 questions. Raceways and Enclosures accounts for 3 questions, while Electrical Power, Low Voltage, and Fire and Intrusion Detection and Alarm Systems each account for 2 questions.

Open Book Test

The Nevada C-2F Residential Wiring Contractor examination is an open-book test.

The following reference included in this package is allowed into the examination:

• NFPA 70 - National Electrical Code, 2017 edition

The following books are included for study but are not allowed into the trade examination room:

• Ugly's Electrical References
• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)

Because the NEC is the primary exam-room reference, candidates should use it throughout preparation. The highlighted and tabbed format can help make important sections easier to revisit, but candidates should also become familiar with the overall structure of the code.

Open-book testing still requires strong electrical knowledge. With 50 questions in two hours, candidates have a little more than two minutes per question on average. Searching the NEC without understanding the topic can take too much time.

A more efficient approach is to recognize the electrical subject first, identify the likely article or section, and then use the NEC to confirm the requirement. Candidates should practice this process with services, feeders, grounding, conductors, raceways, overcurrent protection, and other major residential wiring subjects.

Highlighted sections and tabs can support faster navigation, but they work best when candidates already understand what each article covers. Repeated study with the prepared book can help build that familiarity.

Licensing Steps

1. Confirm the C-2F classification. Make sure Residential Wiring matches the electrical work the business intends to perform.
2. Identify the qualifying individual. The contractor application must identify the person responsible for satisfying the applicable trade qualification requirements.
3. Prepare qualifying experience information. Organize the work-history documentation required for the C-2F classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. After the application and qualification information are reviewed, the qualifying individual can proceed with the required examinations.
6. Prepare for the C-2F trade examination. Study services, feeders, branch circuits, grounding and bonding, conductors, overcurrent protection, raceways, safety, electrical calculations, and low-voltage topics.
7. Practice NEC navigation. Use the highlighted and tabbed NFPA 70 National Electrical Code, 2017 edition throughout preparation.
8. Prepare for Nevada Business and Law. Contractor applicants must satisfy the applicable Nevada business and law requirement unless an authorized waiver applies.
9. Complete the required examinations. Take the applicable trade and business examinations.
10. Complete remaining licensing requirements. Finish the additional requirements associated with contractor license issuance.

State Requirements

Nevada recognizes C-2F Residential Wiring as a subclassification within the C-2 Electrical classification.

The C-2F scope covers the installation, alteration, and repair of electrical wires, fixtures, appliances, and apparatuses whose electrical current does not exceed 600 volts on new or existing structures that do not exceed more than three stories above the ground.

This means the classification is focused on residential electrical work within defined limits. Candidates should understand both the voltage limitation and the building-height limitation when evaluating the type of work authorized by the classification.

Residential wiring work can involve service equipment, feeders, branch circuits, panelboards, grounding and bonding, raceways, cables, receptacles, switches, lighting, appliances, overcurrent protective devices, and other electrical equipment within the authorized scope.

Because residential electrical work directly affects life safety and property protection, candidates should understand conductor sizing, grounding, bonding, overcurrent protection, wiring methods, boxes, raceways, equipment installation, and the code provisions that apply to these systems.

The C-2F trade examination is one part of Nevada contractor licensing. Applicants must also satisfy applicable qualification, application, business and law, financial, and other licensing requirements before a contractor license is issued.

Exam Room Approved Books

• NFPA 70 - National Electrical Code, 2017 edition
  This highlighted and tabbed reference is the exam-room-approved book included with the Nevada C-2F Residential Wiring Contractor Highlighted & Tabbed Book Package. Candidates should use it regularly during preparation to build familiarity with definitions, articles, tables, grounding rules, conductor requirements, service provisions, and residential wiring requirements.

Test Information and Study Materials

A strong Nevada C-2F study plan should begin with Service, Feeders, and Branch Circuits. Review service conductors, service equipment, disconnects, feeder arrangements, branch circuits, panelboards, load relationships, and common residential applications.

General Electrical Knowledge should include voltage, current, resistance, power, circuit relationships, terminology, equipment, and the practical concepts needed to understand code requirements.

Grounding and Bonding deserves substantial attention. Candidates should understand grounding electrode systems, equipment grounding conductors, grounding electrode conductors, grounded conductors, bonding, and the purpose of an effective fault-current path.

Grounding terminology can be challenging because several terms sound similar but have different meanings. Use the highlighted NEC definitions and grounding sections to reinforce the distinctions during study.

Conductors and Cables should include conductor materials, insulation types, ampacity, temperature ratings, conductor identification, cable assemblies, and sizing considerations.

The highlighted and tabbed NEC can help candidates practice locating conductor tables, adjustment factors, correction factors, and notes that can affect conductor selection.

Overcurrent Protection should include circuit breakers, fuses, conductor protection, branch-circuit relationships, equipment protection, and the purpose of limiting current during overloads and fault conditions.

Raceways and Enclosures should include raceway types, boxes, fittings, protection from physical damage, support, conductor fill, and common installation requirements.

Electrical Power preparation should include common electrical formulas and calculations. Ugly's Electrical References can support this study by providing practical formula and conversion information.

Because Ugly's Electrical References is not allowed into the exam, candidates should eventually practice performing common calculations without relying on the book.

Low Voltage and Fire and Intrusion Detection and Alarm Systems should also be reviewed. Even though these categories contain fewer questions, they still contribute toward the required passing score.

Safety Information should be studied carefully because OSHA 29 CFR Part 1926 is not available in the exam room. Candidates should review electrical hazards, personal protective equipment, ladders, tools, fall protection, temporary conditions, and general construction safety practices.

The 2017 National Electrical Code should be used during every study session. The highlighted and tabbed preparation can help candidates return to important sections quickly while building familiarity with the organization of the book.

Start with the table of contents and major chapter structure. Then work through Article 100 definitions, Chapter 2 wiring and protection, Chapter 3 wiring methods and materials, and equipment articles that frequently apply to residential installations.

The NEC index is also a valuable navigation tool. When the correct article is not immediately known, search for the technical term used in the question and follow the reference to the appropriate section.

Practice reading beyond the first matching sentence. NEC requirements can contain exceptions, related subsections, tables, notes, and conditions that affect how the rule applies.

A useful study exercise is to choose a subject such as service disconnects, grounding electrodes, conductor ampacity, receptacle circuits, overcurrent protection, or raceways and find the applicable code material under a time limit.

Repeat the same type of lookup until the search path becomes familiar. Highlighting and tabs can reduce navigation time, but repetition is what helps candidates recognize where to begin.

Practice questions should first be organized by subject. Work separately on services, grounding, conductors, overcurrent protection, raceways, calculations, and safety. Once those topics are comfortable, move into mixed practice.

Mixed practice is important because the examination moves between different electrical subjects. Candidates should become comfortable switching quickly from a service question to grounding, conductor sizing, raceways, or overcurrent protection.

Time management should also be part of preparation. With 50 questions in two hours, spending too long on one difficult lookup can reduce the time available for easier questions.

A balanced approach is to answer familiar electrical questions efficiently, use the NEC for targeted confirmation, mark difficult items, and return to them after completing the easier portion of the exam.

Please allow up to 15 business days for tabbed and highlighted book package orders.
