Article 404 is associated with which component in electrical systems?

Article 404 of the National Electrical Code (NEC) specifically deals with switch installations and requirements. It outlines the standards governing the installation and use of various types of switches—including general-purpose switches, dimmer switches, and dual-switch configurations, among others. Switches are crucial components in electrical systems as they control the power to lighting and other circuits, making their safe installation and operation essential for both functionality and safety.

In the context of the NEC, this article ensures that switches are properly rated for their intended use and that they are installed according to specified guidelines to prevent hazards like electrical shorts or fires. It covers aspects such as switch location, mounting, and necessary clearances, emphasizing safety and compliance with building codes.

Understanding the role of Article 404 helps electricians and inspectors ensure that switch installations meet the required safety standards, thereby promoting safe electrical practices in residential, commercial, and industrial settings.
