Low-Voltage Wiring, Installation, and Safety Practices
Introduction
This comprehensive practice examination is designed to prepare candidates for the Connecticut Limited Electrical
Journeyperson (Low Voltage) L-6 licensing exam. The exam assesses the candidate's knowledge of the Connecticut
General Statutes, the National Electrical Code (NEC), and industry standards such as NFPA 72 for fire alarms. It
evaluates foundational electrical theory, applied professional knowledge, regulatory compliance, and real-world
decision-making skills. The format includes multiple-choice questions and scenario-based problems, reflecting the
actual exam's emphasis on practical application and safe, code-compliant work practices. Mastery of these topics is
essential for ensuring public safety and professional competence in the low-voltage field.
,SECTION ONE: QUESTIONS 1–100
Question 1
According to Connecticut regulations, what is the maximum voltage for an L-6 limited electrical system where work
commences at an outlet receptacle or connection previously installed by a properly licensed person?
A. 12 volts or 3 amperes
B. 25 volts or 5 amperes
C. 48 volts or 8 amperes
D. 120 volts or 15 amperes
🟢 B. 25 volts or 5 amperes
🔴 Explanation: Connecticut state statutes explicitly limit the work of an L-6 licensee to circuits not exceeding 25
volts or 5 amperes when work begins at an existing outlet receptacle. This restriction defines the scope of low-
voltage work permitted under this license classification .
Question 2
Which article of the National Electrical Code (NEC) provides the specific requirements for power-limited fire alarm
circuits?
A. Article 725
B. Article 760
C. Article 800
D. Article 300
🟢 B. Article 760
,🔴 Explanation: NEC Article 760 is the dedicated section that covers the installation of fire alarm circuits, including
both power-limited and non-power-limited wiring. It provides specific rules for these systems to ensure they operate
reliably in a fire emergency. Article 725 covers remote-control and signaling circuits generally, while Article 800
addresses communications circuits .
Question 3
An end-of-line resistor (EOLR) is used in a conventional fire alarm circuit to:
A. Increase the alarm volume of notification appliances.
B. Draw more current during an alarm state.
C. Allow the panel to supervise the wiring for open or short circuits.
D. Step down the voltage to a safe level for initiating devices.
🟢 C. Allow the panel to supervise the wiring for open or short circuits.
🔴 Explanation: The EOLR is placed at the end of the circuit to provide a known resistance value. The fire alarm
control panel (FACP) monitors this resistance; a change indicates a fault (open or short circuit), ensuring the system's
integrity is constantly supervised .
Question 4
What is the primary standard governing the installation, testing, and maintenance of fire alarm systems in the United
States?
A. NFPA 70 (National Electrical Code)
B. NFPA 72 (National Fire Alarm and Signaling Code)
C. NFPA 101 (Life Safety Code)
D. NFPA 90A (Standard for Air Conditioning Systems)
🟢 B. NFPA 72 (National Fire Alarm and Signaling Code)
, 🔴 Explanation: NFPA 72 is the nationally recognized standard that provides comprehensive requirements for fire
alarm systems, covering everything from system design and installation to testing and maintenance. While other
codes reference fire alarm systems, NFPA 72 is the primary governing document .
Question 5
A "Class 2" power-limited circuit, as defined by the NEC, has a maximum power output of:
A. 25 VA
B. 50 VA
C. 100 VA
D. 240 VA
🟢 C. 100 VA
🔴 Explanation: According to NEC Article 725, a Class 2 power-limited circuit has a maximum power output of 100
VA. This is a key safety characteristic that limits the potential for fire and shock hazards, distinguishing it from Class 1
circuits .
Question 6
Which of the following is a characteristic of a "fail-secure" electric lock used in an access control system?
A. The lock is unlocked when power is applied.
B. The lock is locked when power is removed.
C. The lock is unlocked when power is removed.
D. The lock does not require power to operate.
🟢 B. The lock is locked when power is removed.
