SECTION ONE: QUESTIONS 1–50
════════════════════════════════════
1. What is the primary purpose of a low-voltage transformer in outdoor lighting
systems?
A. Increase voltage for long-distance transmission
B. Convert 120V to a safer low voltage
C. Store electrical energy
D. Regulate current frequency
🟢 Correct Answer: B. Convert 120V to a safer low voltage
🔴 Explanation: Transformers reduce standard household voltage to safer levels (typically
12V–24V) for outdoor lighting systems.
2. Which wire type is most commonly used for low-voltage landscape lighting?
A. THHN
, B. Romex
C. Direct burial cable
D. Coaxial cable
🟢 Correct Answer: C. Direct burial cable
🔴 Explanation: Direct burial cable is designed to withstand soil exposure and moisture in
outdoor installations.
3. What is the recommended maximum voltage drop for outdoor lighting systems?
A. 25%
B. 10%
C. 5%
D. 1%
🟢 Correct Answer: C. 5%
🔴 Explanation: Keeping voltage drop under 5% ensures proper brightness and system
efficiency.
4. What device prevents overloading in lighting circuits?
A. Transformer
B. Breaker
C. Switch
D. Relay
🟢 Correct Answer: B. Breaker
🔴 Explanation: Circuit breakers automatically disconnect power when overload conditions
occur.
, 5. What is the purpose of a photocell in outdoor lighting systems?
A. Increase voltage output
B. Detect motion
C. Control lights based on ambient light
D. Store energy
🟢 Correct Answer: C. Control lights based on ambient light
🔴 Explanation: Photocells turn lights on at dusk and off at dawn automatically.
6. Which tool is essential for measuring voltage in a lighting circuit?
A. Clamp meter
B. Multimeter
C. Wire stripper
D. Fish tape
🟢 Correct Answer: B. Multimeter
🔴 Explanation: A multimeter measures voltage, current, and resistance.
7. What is the primary hazard when working with outdoor lighting systems?
A. High temperature
B. Electrical shock
C. Noise pollution
D. Chemical exposure
🟢 Correct Answer: B. Electrical shock
🔴 Explanation: Improper handling of electrical circuits can result in shock hazards.
