Nevada Constructing, Altering or Improving Contractor (C-42) Books Allowed into Exam Package

Prepare for the Nevada C-42 Constructing, Altering or Improving Video Service Networks trade examination with a focused exam-room book package built around the reference permitted for use during the test. This package includes the NFPA 70 - National Electrical Code, 2017 edition, the primary code reference candidates can use while completing the Nevada C-42 trade examination.

The Nevada C-42 classification is officially associated with constructing, altering, or improving video service networks. Candidates preparing for this license should be comfortable with electrical-code requirements that apply to communications and cable installations, along with the broader trade knowledge needed for video service network work.

This package is intended specifically for candidates who want the book allowed into the examination room rather than a broader study-reference package. It does not include additional study-only books such as the National Electrical Safety Code or Data, Voice, and Video Cabling.

The 2017 National Electrical Code should be used throughout the study process so candidates become familiar with its layout, article structure, index, terminology, and the code provisions most likely to apply to communications and cable installations. Open-book testing rewards candidates who know how to navigate the reference efficiently rather than those who attempt to search the entire code book for every question.

Because the C-42 exam also includes significant cable-general knowledge, candidates should combine NEC navigation practice with practical understanding of cable systems, installation methods, connectors, terminations, routing, components, testing, grounding, bonding, and related industry practices.

Exam Details

The Nevada C-42 Constructing, Altering or Improving Video Service Networks trade examination is administered through PSI for candidates who receive examination eligibility through the Nevada State Contractors Board.

• Exam: Nevada C-42 Constructing, Altering or Improving Video Service Networks
• Testing Provider: PSI
• Number of Questions: 35
• Time Allowed: 1 hour
• Minimum Passing Score: 25 correct answers

The examination is divided into three primary subject areas:

• NEC: 10 questions
• NESC: 2 questions
• Cable-General: 23 questions

Cable-General is the largest portion of the examination with 23 questions. Candidates should expect the test to emphasize practical cabling knowledge, including cable types, installation practices, routing, connectors, terminations, system components, testing concepts, and general communications-cabling principles.

NEC accounts for 10 questions. The included NFPA 70 - National Electrical Code, 2017 edition supports preparation for this portion of the exam. Candidates should become familiar with the sections that apply to communications systems, cable installations, grounding, bonding, wiring methods, and separation requirements.

NESC accounts for two questions. Although the National Electrical Safety Code is not included in this exam-room-only package, candidates should still understand the applicable safety concepts as part of their overall preparation.

With 35 questions to complete in one hour, time management matters. Candidates have less than two minutes per question on average. Efficient NEC navigation can help preserve time for cable-general questions that depend more heavily on trade knowledge.

Open Book Test

The Nevada C-42 Constructing, Altering or Improving Video Service Networks examination is an open-book test with designated reference material permitted in the examination room.

The book included in this package and allowed into the C-42 examination is:

• NFPA 70 - National Electrical Code, 2017 edition

The National Electrical Code is a large technical reference, so candidates should avoid treating the open-book format as a substitute for preparation. The most effective approach is to learn where major topics are located and practice moving from a question to the appropriate article or section quickly.

Candidates should become comfortable using the index, table of contents, article structure, definitions, and cross-references. Familiarity with the book can make it easier to recognize whether a question is likely to involve communications systems, grounding, bonding, wiring methods, raceways, cable support, separation, or another code topic.

Because only 10 of the 35 questions are specifically categorized as NEC questions, candidates should also develop strong technical knowledge outside the code book. Cable-General represents most of the exam, so practical cabling knowledge remains essential.

Licensing Steps

The Nevada State Contractors Board regulates the C-42 classification. Passing the trade examination is one part of the complete Nevada contractor licensing process.

1. Confirm the C-42 classification. Determine that constructing, altering, or improving video service networks matches the type of contracting work the business intends to perform.
2. Identify the qualifying individual. Designate the person who will satisfy the applicable experience and examination requirements.
3. Document qualifying experience. Prepare records describing relevant work involving video service networks, communications cabling, cable installation, routing, terminations, system components, testing, and related responsibilities.
4. Prepare the contractor license application. Gather the required business information, qualifier information, experience documentation, financial information, and supporting materials.
5. Submit the application. The Nevada State Contractors Board reviews the applicant's qualifications before examination eligibility is established.
6. Complete applicable background requirements. Follow required disclosure, fingerprint, and background procedures associated with Nevada contractor licensing.
7. Meet applicable financial responsibility requirements. Provide the financial information required as part of the licensing process.
8. Receive examination eligibility. Candidates required to test can proceed with scheduling after authorization.
9. Schedule the C-42 examination through PSI. Arrange the trade exam after receiving eligibility.
10. Prepare for the trade examination. Review NEC requirements, cable-general topics, NESC concepts, and efficient code-navigation methods.
11. Complete applicable contractor management requirements. Nevada contractor licensing also includes management qualification in addition to the trade exam.
12. Complete remaining licensing requirements. Satisfy applicable financial, bonding, background, and other Nevada State Contractors Board requirements before license issuance.

State Requirements

The Nevada C-42 classification is designated for Constructing, Altering or Improving Video Service Networks. A contractor holding this classification may perform work within that defined specialty scope.

The classification is narrower than unrestricted electrical contracting. Candidates should understand that the C-42 license is centered on video service network infrastructure and related systems rather than the full range of electrical construction work.

The exam reflects this specialized scope. Cable-General accounts for 23 of the 35 questions, making technical knowledge of communications cabling and video service network systems a major part of preparation.

Applicants pursuing the C-42 classification must also satisfy applicable Nevada contractor licensing qualifications. Experience should relate to the scope of the classification and should be documented clearly enough to show the nature of the candidate's responsibilities.

Relevant experience may involve cable installation, routing, terminations, connectors, system components, testing, communications infrastructure, video service network construction, alteration, improvement, or supervision of related work.

Passing the C-42 trade examination does not automatically result in license issuance. Applicants must also satisfy the applicable Nevada State Contractors Board requirements involving experience, contractor management qualification, financial responsibility, bonding, background procedures, and other licensing requirements.

Reference Books

• NFPA 70 - National Electrical Code, 2017 edition
  Exam-room-approved code reference supporting preparation involving communications systems, cable installations, grounding, bonding, wiring methods, separation requirements, and other NEC provisions relevant to video service network work.

Exam Room Approved Books

• NFPA 70 - National Electrical Code, 2017 edition
  This is the designated exam-room reference included in the Nevada C-42 Books Allowed into Exam Package.

This package is focused specifically on the reference candidates can bring into the Nevada C-42 trade examination. It does not include the National Electrical Safety Code, 2012 or Data, Voice, and Video Cabling.

Candidates should practice using the NEC before test day. Knowing the general location of applicable topics can make a meaningful difference in a one-hour examination where every lookup consumes part of the available testing time.

Test Information and Study Materials

A productive C-42 study plan should reflect the exam weighting. Because Cable-General represents 23 of the 35 questions, candidates should dedicate substantial preparation time to practical cabling knowledge while also building strong NEC navigation skills.

Practice cable terminology. Candidates should understand commonly used cable types, connectors, components, pathways, terminations, installation methods, testing concepts, and communications infrastructure terminology.

Study installation practices. Review cable routing, support, protection, separation, termination, and general workmanship considerations associated with video service network installations.

Develop NEC navigation skills. Use the 2017 National Electrical Code regularly rather than waiting until the final stage of preparation. Repeated navigation builds familiarity with the structure of the book and helps candidates recognize where information is likely to be located.

Use the index strategically. The NEC index is especially useful when the candidate can identify the correct technical term from the question. Practice extracting key words from a question and tracing them to the appropriate article or section.

Review grounding and bonding. Communications and cable systems can involve grounding and bonding requirements, making these concepts important areas for code-based study.

Understand separation requirements. Candidates should be familiar with how communications and cable installations relate to other wiring systems and where applicable separation or installation rules can be found.

Practice timed lookups. Candidates have only one hour for the entire 35-question exam. Practice finding NEC answers within a limited amount of time so a single difficult lookup does not interfere with the rest of the test.

Know when not to use the book. Many Cable-General questions may be answered from trade knowledge rather than a direct NEC lookup. Candidates should avoid searching the code book unnecessarily when the question is testing practical cabling knowledge.

Review weak areas repeatedly. Practice questions can help reveal whether more study is needed in code navigation, cable types, system components, installation practices, grounding, bonding, or general communications concepts.

Build familiarity with the approved reference. The National Electrical Code is most useful when the candidate has already practiced navigating it under study conditions. Familiarity can help reduce time spent searching and make the open-book format more effective.
