Wiring devices are essential components in electrical systems that facilitate the connection and control of electrical circuits. Common examples include switches, outlets, and plugs, which allow users to turn electrical devices on and off or connect them to a power source. These devices are designed to ensure safe and efficient electrical flow in homes and buildings. Typically made from durable materials, wiring devices come in various shapes and sizes to accommodate different applications. They are often installed in walls or ceilings and can be found in both residential and commercial settings. Proper installation and maintenance of wiring devices are crucial for electrical safety and functionality.
