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.
Gang Boxes are made using insulating plastic materials that safely act as a barrier between the internal live wires or connections and the users. By enclosing the wires and terminals, they also reduce the amount of dust that settles on them – ensuring a trouble-free use for a longer time.
Many hobbyists and electricians use gang boxes to make inexpensive DIY extension cords. You can find several videos and articles on the internet explaining how to create them. It gives them the flexibility to create customizable extension cords according to their specific application requirements.
