An electrical box is an enclosure that houses electrical connections, switches, or outlets to protect wiring and meet code requirements.

An electrical box is a protective enclosure used to contain electrical wiring connections, switches, outlets, and fixtures. It provides a secure, code-compliant way to organize electrical components while protecting them from damage and reducing fire and shock hazards.

In construction, electrical boxes are installed during the rough-in phase and are available in various shapes, sizes, and materials, including plastic and metal. Different box types are used depending on application, such as junction boxes, switch boxes, outlet boxes, and ceiling boxes. Proper box sizing is critical to prevent overcrowding of wires and ensure safe operation.

From a code and safety perspective, electrical boxes must be installed flush with finished surfaces, properly grounded when required, and accessible for inspection and maintenance. Building and electrical codes specify box fill limits, mounting requirements, and approved uses to ensure long-term safety and performance.

Electrical box size is regulated by code to prevent overheating caused by overcrowded wires.
