Which of the following articles includes information about luminaires and lamps?

Article 410 of the National Electrical Code specifically deals with luminaires, which are the complete lighting units, and lamps, which are the light sources used in those units. This article covers the installation and requirements for different types of luminaires, such as fixtures and track lighting, and addresses their safety and usage standards. The regulations outlined in this article aim to ensure that lighting is not only effective but also safe for installation and operation in various environments, including residential, commercial, and industrial settings.

Other articles listed in the options pertain to different electrical devices and systems. For instance, Article 424 deals with hydronic equipment, Article 422 addresses appliances, and Article 406 focuses on receptacles and cords. Each of these articles has its own specific focus and does not include comprehensive information regarding luminaires and lamps. Thus, Article 410 is the only choice that directly pertains to the subject matter of luminaires and lamps, making it the correct answer.
