GEORGIA LOW-VOLTAGE CONTRACTOR
LV-T EXAM 2026/2027 QUESTIONS WITH
VERIFIED ANSWERS & COMPLETE
RATIONALES
**1. What is the primary purpose of a low-voltage system?**
A. Transmitting high-power electricity
B. Controlling, signaling, or communication
C. Heating buildings
D. Providing backup power
**Correct answer:** B
**Rationale:** Low-voltage systems are designed for
communication, signaling, and control rather than supplying
high-power electricity .
**2. The maximum voltage allowed for a low-voltage system
under Georgia code is:**
,2 | Page
A. 120V
B. 48V
C. 50V
D. 24V
**Correct answer:** C
**Rationale:** Georgia code defines "low-voltage wiring" as
wiring systems of **50 volts or less** and control circuits
directly associated therewith .
**3. Which device is commonly used to protect low-voltage
circuits from overload?**
A. Transformer
B. Fuse or circuit breaker
C. Contactor
D. Relay
**Correct answer:** B
**Rationale:** Fuses and circuit breakers prevent damage to
low-voltage equipment by interrupting overcurrent .

**4. In a structured cabling system, which type of cable is
primarily used for backbone connections?**
A. Cat 5e
B. Cat 6
C. Fiber optic
D. Coaxial
**Correct answer:** C
**Rationale:** Fiber optic cables are used for backbone
connections due to high bandwidth and long-distance
transmission .
**5. For an alarm system, which component detects
unauthorized entry?**
A. Keypad
B. Sensor or detector
C. Control panel
D. Siren
**Correct answer:** B
