Nevada Constructing, Altering or Improving Contractor (C-42) Exam Book Package

Prepare for the Nevada Constructing, Altering or Improving Contractor (C-42) trade examination with an exam book package organized around video service networks, electrical-code requirements, cable installation, system components, and practical cabling knowledge. The official Nevada C-42 classification is Constructing, Altering or Improving Video Service Networks, and candidates should prepare specifically for the electrical and cable-related subjects associated with that scope of work.

This package includes the NFPA 70 - National Electrical Code, 2017 edition, which is the reference approved for use during the Nevada C-42 trade examination. Because the C-42 exam is open book, candidates should become comfortable navigating the 2017 National Electrical Code before test day and understand how its requirements relate to cable and video service network installations.

The package also includes the National Electrical Safety Code, 2012 and Data, Voice, and Video Cabling as study references. These materials support preparation involving outside electrical safety concepts, cable systems, installation practices, components, connectors, testing, and general communications cabling knowledge. These two references are not allowed into the C-42 examination room.

The examination places its greatest emphasis on general cable knowledge, making practical understanding especially important. Candidates should know cable types, installation considerations, connectors, terminations, routing, testing, system components, and common industry practices in addition to learning how to navigate the National Electrical Code.

A strong preparation strategy combines code navigation with technical study. Candidates should not rely on searching the NEC for every answer. The exam includes substantial material based on cable knowledge and industry practices, so effective preparation requires understanding the work as well as knowing how to locate specific electrical-code requirements when needed.

Exam Details

The Nevada C-42 Constructing, Altering or Improving Video Service Networks trade examination is administered through PSI for candidates who have received 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 C-42 examination is divided into three primary subject areas:

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

Cable-General is the largest exam category with 23 of the 35 questions. Candidates should devote significant preparation time to general video, data, and communications cabling concepts. This may include cable characteristics, installation practices, routing, terminations, connectors, system components, testing considerations, and general industry practices relevant to video service networks.

NEC accounts for 10 questions. Candidates should practice using the 2017 National Electrical Code and become familiar with provisions that affect communications, cable installations, grounding, bonding, separation, wiring methods, and related electrical requirements.

NESC accounts for two questions. Although the National Electrical Safety Code is not permitted inside the examination room, candidates should review the 2012 edition during preparation so applicable safety and system concepts can be recalled without the book on test day.

With only one hour to complete 35 questions, pacing is important. Candidates have less than two minutes per question on average. Efficient code navigation and strong cable knowledge can help prevent excessive time from being spent on individual questions.

Open Book Test

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

The exam-room-approved reference included in this package is:

• NFPA 70 - National Electrical Code, 2017 edition

The 2017 National Electrical Code should be used throughout preparation. Candidates should become familiar with its structure, index, terminology, and the portions that apply to communications and cable installations.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used. Temporary tabs such as Post-it notes are not permitted. Candidates should prepare their reference before test day and become familiar with any highlighting or indexing they intend to use.

The following included study references are not allowed into the C-42 examination:

• National Electrical Safety Code, 2012
• Data, Voice, and Video Cabling

These books should be used during preparation to strengthen technical understanding. The National Electrical Safety Code supports preparation for the NESC portion of the examination, while Data, Voice, and Video Cabling supports the much larger Cable-General portion.

Because Cable-General represents 23 questions, candidates should not treat this as an NEC-only examination. The National Electrical Code is an important exam-room tool, but the majority of the test requires broader knowledge of cable systems and common industry practices.

Licensing Steps

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

1. Confirm the C-42 classification. Determine that constructing, altering, or improving video service networks matches the contracting work the business intends to perform.
2. Identify the qualifying individual. Designate the person who will satisfy the applicable experience and examination requirements for the classification.
3. Document qualifying experience. Prepare records describing relevant work involving video service networks, communications cabling, cable installation, system components, routing, terminations, and related responsibilities.
4. Prepare the Nevada 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 application and determines examination eligibility.
6. Complete applicable background requirements. Follow the required fingerprint, disclosure, and background procedures associated with Nevada contractor licensing.
7. Meet applicable financial responsibility requirements. Provide the financial documentation required for the requested contractor license.
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 examination after receiving eligibility.
10. Prepare for the C-42 trade exam. Study cable-general topics, NEC requirements, NESC concepts, and efficient National Electrical Code navigation.
11. Complete applicable contractor management requirements. Nevada contractor licensing also includes contractor management qualification in addition to the trade examination.
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 officially designated for Constructing, Altering or Improving Video Service Networks. A person holding a C-42 license may construct, alter, or improve video service networks.

This classification is specialized around video service network infrastructure rather than unrestricted electrical contracting. Candidates should understand the distinction between video service network work and activities that fall within other Nevada electrical or communications-related classifications.

The trade examination reflects this specialized scope by concentrating heavily on cable-general knowledge. Twenty-three of the 35 questions fall into the Cable-General category, while electrical-code and electrical-safety concepts account for the remaining questions.

Applicants pursuing a Nevada contractor license must also satisfy the licensing qualifications established by the Nevada State Contractors Board. For the standard licensing pathway, qualifying experience generally must demonstrate the required level of practical experience in the classification requested.

Experience documentation should clearly describe relevant duties rather than relying only on a job title. Work involving communications cabling, video service network construction, installation methods, cable routing, termination, testing, system components, and related supervision can help demonstrate the nature of the applicant's experience when applicable.

Passing the C-42 trade examination does not by itself issue a Nevada contractor license. Applicants must also satisfy applicable application, experience, management qualification, financial responsibility, bonding, background, and other Nevada State Contractors Board requirements.

Exam Room Approved Books

• NFPA 70 - National Electrical Code, 2017 edition
  This is the exam-room-approved reference included for use during the Nevada C-42 Constructing, Altering or Improving Video Service Networks examination.

The National Electrical Safety Code and Data, Voice, and Video Cabling references are study materials only. Candidates should use them before test day to build knowledge for the NESC and Cable-General portions of the examination.

Test Information and Study Materials

A productive C-42 preparation plan should begin with the exam weighting. Cable-General represents 23 questions, making practical cabling knowledge the clear priority.

Prioritize general cabling knowledge. Review cable types, applications, routing, installation methods, connectors, terminations, system components, testing principles, and common communications-cabling practices.

Study video service network concepts. Understand how cable systems and related components work together to provide video services and how installations may be constructed, altered, or improved.

Practice NEC navigation. Use the 2017 National Electrical Code regularly. Learn how to locate requirements involving communications wiring, cable systems, grounding, bonding, separation, wiring methods, and related installations.

Review NESC concepts before exam day. Because the National Electrical Safety Code cannot be brought into the examination room, candidates should study applicable concepts in advance and be prepared to answer those questions from knowledge.

Know which questions require the NEC. Not every C-42 question is an electrical-code lookup. Recognizing whether a question is primarily NEC-based or cable-general can save valuable testing time.

Practice using the index. The NEC index can be a valuable navigation tool when a candidate knows the terminology associated with the question. Practice identifying key terms and tracing them to the applicable article or section.

Develop familiarity instead of memorizing page numbers. Understanding the organization and article structure of the NEC is generally more useful than relying on page-number memorization, especially when navigating a large code book under time pressure.

Use timed practice. Candidates have one hour for 35 questions. Practice maintaining a steady pace, answering familiar cable questions efficiently, and reserving reference lookups for questions that genuinely require the code.

Review the largest category repeatedly. With nearly two-thirds of the examination devoted to Cable-General, candidates should return to cabling topics throughout their study plan rather than focusing primarily on the NEC.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep supports Nevada C-42 Constructing, Altering or Improving Video Service Networks Contractor candidates through organized study guidance, trade-focused review, practice-oriented preparation, reference navigation when applicable, and confidence-building study structure.

The C-42 examination has a distinctive balance. Candidates need to use the National Electrical Code effectively, but they also need strong cable-general knowledge because the majority of questions are drawn from that subject area. Structured preparation helps keep both parts of the examination in proper proportion.

Reference-navigation practice focuses on the 2017 National Electrical Code. Candidates can work on locating communications, cable, grounding, bonding, and other relevant provisions efficiently instead of searching broadly through the book during the timed examination.

Trade-focused review helps reinforce cable knowledge that cannot be solved simply by opening the NEC. Cable types, installation practices, system components, terminations, connectors, testing, and general video service network concepts all require technical understanding.

The National Electrical Safety Code and Data, Voice, and Video Cabling study materials provide additional preparation for subjects that must be answered without those references in the exam room. Candidates can use them to strengthen weaker areas and reinforce concepts before testing.

Practice-oriented preparation can help candidates determine where additional study is needed. Someone experienced with cable installation may need more NEC navigation practice, while another candidate may need more work with cable terminology, system components, testing, or NESC concepts.

By combining the approved National Electrical Code reference with focused cable and electrical-safety study materials, 1 Exam Prep helps candidates build an organized preparation strategy for the Nevada C-42 trade examination.
