Which situations necessitate special installation considerations for luminaires?

Luminaires classified as low-voltage require special installation considerations because their operating characteristics and safety requirements can differ significantly from standard line voltage installations. Low-voltage systems often use different types of wiring, connectors, and components that are specifically designed to handle lower voltage levels safely. This may include considerations for insulation, grounding, and the choice of compatible fixtures, ensuring the system functions correctly without risking electrical shock or fire hazards.

When luminaires are part of a decorative design or intended for outdoor use, while they may have specific installation practices, these do not inherently change the standard requirements related to voltage. Luminaires operating at standard line voltage typically follow general installation guidelines without the need for additional considerations that come with lower voltage systems. Consequently, the distinction of low-voltage luminaires highlights the unique requirements and precautions that must be taken to ensure safety and compliance with the National Electrical Code.
