Introduction
This practice examination is designed to assess the comprehensive knowledge required for the Nevada C-2D Low
Voltage Contractor license. The exam evaluates competencies in the installation, service, and maintenance of low-
voltage and limited-energy systems, including fire alarms, security, access control, structured cabling, and audio-
video distribution. The 100-question multiple-choice format includes scenario-based questions that test the
application of the National Electrical Code, NFPA standards, and Nevada-specific regulations to real-world
installation and troubleshooting situations. Candidates must demonstrate critical thinking in system design, code
,compliance, grounding practices, and job-site safety. Mastery of this material confirms the professional decision-
making skills necessary to perform as a licensed low-voltage contractor in the State of Nevada, ensuring public
safety and system integrity.
SECTION ONE
Question 1
According to the Nevada State Contractors Board, the C-2D classification authorizes a licensed contractor to
perform which scope of work?
A. High-voltage electrical transmission line installation
B. Installation, repair, and maintenance of low-voltage systems including fire alarms, security, sound, and
telecommunications
C. General building construction including framing and concrete
D. Plumbing and mechanical system installation only
🟢 Correct Answer:
B
🔴 RATIONALE:
The Nevada C-2D classification specifically covers low-voltage and limited-energy systems. This includes fire
detection and alarm systems, intrusion and security systems, closed-circuit television, access control, sound
systems, telephone and data cabling, and other systems operating at 91 volts or less, as defined by the Nevada
State Contractors Board.
,Question 2
Which NEC article specifically governs the installation of fire alarm and signaling system wiring?
A. NEC Article 800
B. NEC Article 760
C. NEC Article 725
D. NEC Article 820
🟢 Correct Answer:
B
🔴 RATIONALE:
NEC Article 760 covers the installation of wiring and equipment for fire alarm systems, including detection and
notification circuits. Article 800 covers communications circuits, Article 725 covers Class 1, 2, and 3 remote-
control and signaling circuits, and Article 820 covers community antenna and radio distribution systems.
Question 3
In Nevada, a low-voltage contractor must hold a valid C-2D license issued by which state agency?
A. Nevada Department of Business and Industry
B. Nevada State Contractors Board
C. Nevada Public Utilities Commission
D. Nevada Occupational Safety and Health Administration
, 🟢 Correct Answer:
B
🔴 RATIONALE:
The Nevada State Contractors Board is the regulatory body responsible for issuing all contractor licenses in the
state, including the C-2D Low Voltage classification. The Board establishes licensing requirements, administers
examinations, and enforces compliance with Nevada contractor law.
Question 4
What is the maximum voltage level that defines a "low-voltage" system under the typical scope of the C-2D
classification in Nevada?
A. 48 volts
B. 70 volts
C. 91 volts
D. 120 volts
🟢 Correct Answer:
C
🔴 RATIONALE:
The C-2D classification in Nevada limits low-voltage work to systems operating at a maximum of 91 volts. This
threshold aligns with the NEC's definition of Class 2 and Class 3 limited-energy circuits and distinguishes low-
voltage work from standard electrical wiring, which requires a different license classification.
