✍️ Sample LLC Questions & Answers
1. An installer finds existing landscape wiring spliced inside a weathertight junction box buried underground without conduit fill. What NEC violation exists?
NEC Section 300.15 requires that all junction boxes remain accessible; a buried box without an accessible cover violates this rule.
2. Why is it important to document 'before' and 'after' voltage readings at fixture terminals in a PM report?
Before-and-after voltage documentation proves the value of PM work by showing measurable improvements in system voltage and performance resulting from the technician's actions.
3. When landscape lighting conductors are run in PVC conduit underground, the minimum burial depth under a public sidewalk is:
NEC Table 300.5 requires PVC conduit under sidewalks to be buried at least 12 inches deep.
4. How does collaboration enhance Tools & Equipment Operation in Landscape Lighting Certification?
Collaboration brings together different viewpoints and expertise, leading to better decision-making and outcomes.
5. In a low-voltage landscape lighting transformer, what does the 'timer' feature control?
The built-in timer in a landscape lighting transformer allows the installer to program specific on/off schedules for the connected lighting zones.
6. Which of the following actions is required before energizing a newly completed landscape lighting system for final inspection?
Verifying that all fixtures carry the correct Listing (wet, damp, or dry) for their actual installed environment is a fundamental compliance check before energizing.
