What is the main subject of Article 411?

The main subject of Article 411 of the National Electrical Code (NEC) specifically addresses low-voltage lighting systems. This article outlines the necessary requirements for the installation and use of low-voltage lighting, including safety considerations and technical standards. Low-voltage lighting is often utilized for decorative purposes, task lighting, and other applications, making it essential for electricians to understand the guidelines set forth in this article to ensure compliance with the NEC.

In contrast, other articles mentioned focus on different electrical topics: fixed electric heating equipment encompasses systems designed for permanent heating installations, industrial control panels cover the construction and use of control equipment in industrial settings, and fixed resistance heating equipment pertains to devices that produce heat through electrical resistance. Each of these areas has its own distinct requirements and regulations, separate from the low-voltage lighting focus of Article 411.
