Nevada Low Voltage Contractor (C-2D) Exam Book Package

Prepare for the Nevada Low Voltage Contractor (C-2D) examination with an exam book package focused on electrical code navigation, low voltage systems, telecommunications wiring, conductors, grounding and bonding, wiring methods, communications systems, equipment installation, and other technical knowledge associated with low voltage contracting in Nevada.

This package includes the NFPA 70 - National Electrical Code, 2017 edition and Telecommunications Wiring, Clyde Herrick, 2001, 3rd Edition. The National Electrical Code is the reference included for exam-room use, while Telecommunications Wiring is a supplemental study reference and is not allowed inside the examination room.

Nevada classifies C-2D as Low Voltage Systems. The classification covers the installation, alteration, and repair of systems using fiber optics or operating at no more than 91 volts. The scope includes telephone systems, sound systems, cable television systems, closed-circuit video systems, satellite dish antennas, instrumentation and temperature controls, computer networking systems, and landscape lighting.

This broad scope means candidates should be comfortable with more than one type of limited-energy system. Preparation can involve communications cabling, data systems, sound and video, grounding and bonding, conductor selection, pathways, raceways, boxes, terminations, power supplies, equipment, and the electrical-code requirements that apply to low voltage installations.

The NFPA 70 - National Electrical Code, 2017 edition is especially important because candidates should be able to locate code provisions efficiently during open-book preparation. Knowing how to use the index, article structure, definitions, tables, exceptions, and cross-references can help candidates approach code-based questions more effectively.

Telecommunications Wiring, Clyde Herrick, 2001, 3rd Edition provides supplemental preparation for telecommunications cabling and related communications-system concepts. Because this book is not allowed inside the exam room, it should be used to build knowledge before test day rather than as a reference-navigation tool for the examination itself.

Exam Details

The Nevada Low Voltage Contractor (C-2D) trade examination evaluates knowledge related to low voltage electrical systems and the technical responsibilities associated with installing, altering, and repairing those systems.

Candidates should prepare for questions involving general electrical knowledge. Even though C-2D work is focused on low voltage systems, a contractor still needs a working understanding of electrical terminology, voltage, current, resistance, power, conductor characteristics, grounding, equipment, and safe installation practices.

Grounding and bonding should receive dedicated study time. Candidates should understand grounding terminology, bonding concepts, grounding conductors, equipment grounding, and the role of grounding and bonding in protecting equipment and reducing electrical hazards.

Conductors and cables are another central preparation area. Low voltage systems depend on correct cable and conductor selection, routing, support, termination, protection, and identification. Candidates should understand how installation conditions affect wiring methods and how different low voltage systems may require different cabling approaches.

Communications systems are particularly relevant to C-2D work. Telephone, networking, sound, video, cable television, closed-circuit video, and related systems can require candidates to understand pathways, cabling, equipment connections, separation, grounding, and installation practices.

Raceways, boxes, and pathways should also be reviewed. Candidates should understand when wiring needs physical protection, how cables are routed through buildings, how enclosures and raceways are used, and how electrical-code requirements affect installation.

Preparation should also address power supplies and equipment. Many low voltage systems rely on transformers, power supplies, control equipment, communication hardware, or interfaces with other electrical systems. Candidates should understand the basic role of these components and the requirements affecting their installation.

Open Book Test

The Nevada Low Voltage Contractor (C-2D) examination is an open-book test using the approved electrical code reference included with this package.

The book included for exam-room use is:

• NFPA 70 - National Electrical Code, 2017 edition

The following book is included for study but is not allowed inside the examination room:

• Telecommunications Wiring, Clyde Herrick, 2001, 3rd Edition

Open-book testing should not be treated as an opportunity to look up every answer from scratch. Candidates benefit from learning the structure of the National Electrical Code before exam day. Practice should include finding articles through the index, recognizing common NEC terminology, working with definitions, using tables, and following cross-references.

A practical method is to identify the subject before opening the NEC. If a question involves grounding, first determine whether it concerns bonding, equipment grounding, grounding electrodes, or another grounding concept. If the question involves communications wiring, identify the system involved and then locate the applicable code subject.

Use Telecommunications Wiring for deeper study of cabling concepts, telecommunications pathways, installation principles, and communication-system terminology. Since the book cannot be used inside the exam room, candidates should practice recalling those concepts without the reference after reviewing them.

Licensing Steps

The Nevada C-2D trade examination is one part of the contractor licensing process. Candidates must satisfy the applicable licensing requirements in addition to preparing for the trade exam.

1. Confirm the C-2D classification. Make sure the work the business intends to perform falls within Nevada's Low Voltage Systems subclassification.
2. Identify the qualifying individual. The contractor license application must designate the individual responsible for providing the applicable trade qualification.
3. Document qualifying experience. Prepare applicable work-history information involving low voltage wiring, communications systems, networking, sound, video, controls, fiber optics, or other work within the classification.
4. Complete the Nevada contractor license application. Submit the required business, qualifying individual, experience, financial, and supporting information.
5. Submit the application for review. Nevada contractor examination eligibility is determined through the licensing process.
6. Receive authorization to test. After eligibility is established, the qualifying individual can schedule the applicable examinations.
7. Prepare for the C-2D trade examination. Study NEC navigation, grounding and bonding, conductors, low voltage systems, telecommunications wiring, equipment, raceways, and related technical subjects.
8. Practice with the NEC 2017. Become comfortable locating electrical requirements efficiently using the exam-room reference.
9. Complete applicable examinations. Satisfy the examination requirements associated with the contractor license application.
10. Complete remaining licensing requirements. Finish the other applicable requirements before the contractor license is issued.

State Requirements

Nevada designates C-2D Low Voltage Systems as a subclassification of C-2 Electrical Contracting.

The C-2D scope covers the installation, alteration, and repair of systems that use fiber optics or do not exceed 91 volts. The classification includes several common low voltage and communications technologies.

Work within the classification includes telephone systems, sound systems, cable television systems, closed-circuit video systems, satellite dish antennas, instrumentation and temperature controls, computer networking systems, and landscape lighting.

This variety requires candidates to understand how low voltage electrical principles apply across different technologies. A networking installation may have different equipment and cabling than a sound system, while temperature controls or landscape lighting may involve another set of components. However, fundamental concepts such as conductor routing, electrical protection, grounding, wiring methods, and safe installation remain important throughout the classification.

The contractor licensing process also extends beyond the technical trade exam. Applicants must complete the applicable qualification, application, examination, financial, and other requirements before a Nevada contractor license is issued.

Test Information and Study Materials

A strong C-2D preparation strategy combines electrical-code navigation with practical low voltage knowledge. The NEC should be used regularly during practice, while Telecommunications Wiring should be used to strengthen understanding of communication cabling and installation concepts.

General Low Voltage Knowledge should include limited-energy circuits, equipment, cabling, voltage characteristics, wiring methods, and system installation concepts. Candidates should be able to identify how low voltage systems differ from conventional power wiring while still recognizing the electrical principles that apply to both.

Grounding and Bonding should include terminology, equipment grounding, bonding methods, grounding conductors, and related NEC requirements. Practice locating applicable grounding provisions rather than relying solely on memory.

Conductors and Cables should include conductor properties, cable types, routing, support, protection, termination, separation, identification, and installation conditions.

Telephone and Telecommunications Systems should be studied for cabling methods, pathways, distribution concepts, connections, terminations, equipment, and general installation practices. Telecommunications Wiring can provide useful background preparation in this area.

Computer and Data Systems should include structured cabling concepts, network cabling, pathways, equipment interfaces, and the physical installation considerations involved in data systems.

Sound and Video Systems may involve cabling, equipment, signal distribution, terminations, power considerations, and installation methods. Candidates should understand how these systems fit within the broader C-2D scope.

Closed-Circuit Video Systems should be reviewed for cabling, equipment placement, signal transmission, power, pathways, and installation concepts.

Instrumentation and Temperature Controls should be studied as low voltage control systems that may involve sensors, controllers, wiring, power supplies, and equipment interfaces.

Landscape Lighting is specifically included within the Nevada C-2D classification. Candidates should recognize the electrical and installation considerations associated with low voltage landscape lighting systems.

Raceways and Boxes should be reviewed through the NEC. Understand how conductors and cables are routed and protected, how boxes and enclosures are used, and how wiring methods relate to the installation environment.

Power Supplies should be studied for their role in providing appropriate electrical power to low voltage equipment. Candidates should understand basic transformer and power-supply concepts and how the equipment relates to the connected system.

During NEC practice, begin each question by identifying the main topic. Use the index to locate a likely article or section, then read the surrounding requirements carefully. Pay attention to definitions, exceptions, tables, and references to other sections.

For Telecommunications Wiring, follow each study period with closed-reference review. Read a section, set the book aside, and explain the concept without looking at the text. This method is useful because the telecommunications reference will not be available during the exam.

Practice questions can help identify weak areas. If grounding questions take too long, spend additional time learning NEC grounding terminology and organization. If telecommunications questions are difficult, review cabling and communication-system concepts. If raceways or conductor questions are challenging, increase NEC navigation practice in those areas.

Mixed practice is also useful. Low voltage work often combines multiple topics within one installation. A single system may require cable selection, grounding, pathways, equipment connections, power supplies, and code compliance. Studying these subjects together can help candidates develop a more complete understanding.
