Article 410 covers luminaires and several other items. Which of the following is also included?

Article 410 of the National Electrical Code (NEC) specifically addresses luminaires, which include lighting fixtures, as well as various related components and items associated with lighting. Decorative lighting products fall under this umbrella since they are considered a type of luminaire used to enhance aesthetic appeal while providing illumination in residential, commercial, and industrial settings.

The inclusion of decorative lighting products means that the NEC recognizes the safety and installation requirements for these fixtures, ensuring they are installed in a way that minimizes electrical hazards, just like standard lighting fixtures. This is essential for maintaining safety standards across all types of luminaires used in different environments.

In contrast, items like circuit breakers, transformers, and safety switches are governed by different NEC articles that address their specific functions and requirements. Circuit breakers are covered under Article 240, transformers under Article 450, and safety switches under Article 404, which collectively do not pertain to the luminaire category of Article 410. Therefore, the correct recognition of decorative lighting products aligns with the focus of Article 410 on luminaires.
