What is the primary purpose of accessory boxes in electrical installations?

The primary purpose of accessory boxes in electrical installations is to accommodate devices like switches, outlets, and other types of electrical controls. These boxes are designed to provide a secure and organized space for making electrical connections while helping to keep the wiring contained and protected.

Accessory boxes serve as the mounting point for switches and outlets, allowing for easy access for users while minimizing the risk of accidental contact with live electrical components. By housing these devices within a box, safety is enhanced, as the box also helps contain sparks or heat that may arise from the electrical connections.

While other purposes for electrical boxes exist, such as supporting fixtures or offering some level of protection against electrical faults, the central role of accessory boxes is specifically tied to facilitating the mounting and installation of devices that control or connect electrical circuits, making the correct choice evident.
