Installation procedures for luminaries are outlined in which NEC article?

The installation procedures for luminaires are specifically outlined in Article 410 of the National Electrical Code (NEC). This article covers the requirements and regulations for various types of lighting fixtures, including their proper installation, mounting, and connection to electrical systems. It addresses safety considerations, wiring methods, and other essential factors that ensure luminaires operate safely and effectively.

Article 410 also provides directives regarding the installation of lighting fixtures in different environments, including residential, commercial, and hazardous locations. It is crucial for electricians to be familiar with this article to ensure compliance with code requirements and to maintain safety standards during the installation of lighting systems.

The other articles mentioned do not specifically address luminaires. Article 400 deals with flexible cords and cables, Article 420 pertains to fixed electric space-heating equipment, and Article 500 covers hazardous locations. Therefore, they are not relevant to the installation procedures of luminaires, making Article 410 the correct choice.
