Connecticut (CT) L-6 Limited Electrical Journeyperson EXAM
ACTUAL EXAM COMPLETE 350 QUESTIONS AND VERIFIED
SOLUTIONS LATEST UPDATE THIS YEAR
Connecticut (CT) L-6 Limited Electrical Journeyperson Exam Overview
The L-6 Limited Electrical Journeyperson license in Connecticut is a specialty classification that
permits the installation, maintenance, and repair of low-voltage systems. Under Connecticut
Licensing Rules, the L-6 scope is generally restricted to circuits not exceeding 48 volts and 8
amperes.
Full Exam Content Areas:
National Electrical Code (NEC): Primary focus on Articles 725 (Remote-Control, Signaling, and
Power-Limited Circuits), 760 (Fire Alarm Systems), and 800 (Communication Circuits).
NFPA Standards: Extensive coverage of NFPA 72 (National Fire Alarm and Signaling Code)
and NFPA 70E (Electrical Safety in the Workplace).
System Components: Identification and operation of initiating devices, notification appliances,
and control panels.
Grounding and Bonding: Specific requirements for low-voltage and IT systems as per NEC
Article 250.
Theory and Calculations: Ohm’s Law (), voltage drop, and conduit fill calculations.
First Set of 150: Questions 4-53
The following continues the set covering electrical safety, wiring methods, and fire protection
systems.
4. What is the maximum permissible amperage for a circuit under the L-6 license scope?
A. 5 A
,Page 2 of 223
B. 8 A
C. 15 A
D. 20 A
Answer: B ✅
Rationale: Connecticut regulations limit L-6 journeypersons to low-voltage circuits that draw no
more than 8 amperes.
5. According to the NEC, which article covers communication circuits like telephone and data
networks?
A. Article 725
B. Article 760
C. Article 800
D. Article 645
Answer: C ✅
Rationale: NEC Article 800 specifically addresses communication circuits, including cabling,
grounding, and bonding.
6. Which formula represents Ohm's Law correctly?
,Page 3 of 223
A.
B.
C.
D. Both A and C
Answer: D ✅
Rationale: Ohm's Law defines the relationship between Voltage (
), Current (
), and Resistance (
, Page 4 of 223
); both
and
are mathematically accurate representations.
7. Why is voltage drop a critical factor to consider when designing low-voltage systems?
A. It increases equipment lifespan
B. It ensures proper operation and performance
C. It reduces energy costs
D. It prevents overloads
Answer: B ✅
Rationale: Excessive voltage drop can cause low-voltage equipment to malfunction or fail to
activate; maintaining voltage within limits ensures consistent system performance.
8. For exposed non-current-carrying metal parts of an IT system, what does NEC 645.15
require?
A. They shall be left alone for IT staff to fix
