Which type of installation does NEC Article 410 primarily apply to?

NEC Article 410 specifically addresses the requirements for lighting fixtures and luminaires. This article covers various aspects of installation, including the safety standards, fixture assembly, and locations where such fixtures should or should not be installed.

The emphasis on lighting fixtures and luminaires in this article is vital because it ensures that these systems meet necessary safety codes, thus reducing hazards associated with electrical lights, such as shock or fire risks.

In contrast, the other options focus on different areas of electrical installations that are governed by other NEC articles. Heating systems, for example, are typically covered under separate standards, while power distribution systems and grounding systems have their own articles that focus on the specific requirements and guidelines relevant to those installations. Understanding the specific scope of each NEC article helps ensure compliance with safety standards and effective electrical system performance.
