Which article outlines standards for low-voltage lighting?

The correct choice pertains to Article 411, which specifically addresses the standards and requirements for low-voltage lighting systems. This article is crucial because it defines the categories of low-voltage lighting applications and sets the guidelines for their installation and safety measures. It focuses on systems operating at low voltages, ensuring that they function correctly while minimizing risks associated with electrical hazards.

Article 411 establishes parameters for low-voltage lighting installations, including allowable operating voltages, types of conductors, and necessary clearances from other services to maintain safety and efficiency. The standards outlined in this article are essential for electrical professionals to follow when working with low-voltage designs, ensuring compliance with the National Electrical Code (NEC) and promoting safe practices in electrical installations.
