An electrical box, also known as a junction box, serves as a protective enclosure for wiring connections and electrical devices. Electrical boxes are designed to contain and protect wires, ensuring their safety and organization.
Electrical boxes are essential because they serve as a hub for wiring connections. They provide space for switches, outlets, and other electrical devices.
Yes, electrical boxes are installed according to standard specifications and regulatory requirements. These regulations include guidelines for the use of materials, such as PVC conduit and conduit fittings. To ensure their compliance, it is important to have a licensed professional handle the installation.
Depending on the type and size of your electrical box, the NEC specifies that it must have enough volume to accommodate the wires as well as any necessary conduit fittings. For example, a standard plastic switch or outlet box can accommodate up to eight 14-gauge wires, or six 12-gauge wires.

Proper grounding is crucial for the safe operation of electrical systems. Your electrician will ensure that the boxes are properly grounded, and all connections are secure.
Before purchasing an electrical box, you should determine if it will install in a residential space or a commercial facility. This will help determine the type and size of the electrical box needed:
