Which article is particularly relevant to Appliances and their installation?

Article 422 of the National Electrical Code (NEC) specifically addresses the requirements for the installation of appliances. This includes guidelines on wiring methods, circuit sizing, and the selection of overcurrent protection devices for various types of appliances, such as cooking, heating, and cooling equipment. The intent of this article is to ensure safety and efficiency in the installation and utilization of appliances within residential and commercial settings.

By focusing on the specific characteristics and operational needs of appliances, Article 422 provides clear standards that help prevent hazards related to electrical appliances, such as overheating or electrical fires. This makes it essential for electricians and installers to be familiar with this article when working on or near appliances.

In contrast, Articles 430 and 440 pertain to motor circuits and hermetic refrigerating equipment, respectively, while Article 411 addresses low-voltage lighting systems. Therefore, these articles serve different purposes and are not centered on the general installation requirements for appliances. Understanding the distinctions between these articles is crucial for ensuring compliance with the NEC and optimizing electrical safety in various installations.
