Non-Modular Gang Boxes are used to encase electrical components such as switches, sockets, dimmers, etc. The main purpose of a gang box is to provide the framework for distributing the main power supply across various devices and appliances. The idea is that you can “gang” up electrical components in the box, hence the name.
Gang Boxes are one of the most commonly used devices for making household power connections. A gang box houses switches, sockets, and other devices used to operate various electrical appliances.
