There are several types of electrical boxes used in residential, commercial, and industrial electrical systems. These boxes serve as a protective enclosure for electrical wires and components.

What Are The Types of Electrical Boxes?

Electrical Box

Some common types of electrical boxes include:


  • Junction boxes: These are used to connect two or more electrical circuits or wires together. They can be either surface-mounted or recessed, and they come in various sizes to accommodate the number of wires and connections needed. Junction boxes must be properly sized and rated for the amount of current they will be carrying.
  • Outlet boxes: These boxes are used to hold electrical outlets and receptacles. They can be mounted on a wall or ceiling, and they come in various sizes to accommodate different types and numbers of outlets. Outlet boxes must also be properly sized and rated for the amount of current they will be carrying.
  • Switch boxes: These boxes are used to hold switches that control the flow of electricity to various electrical devices. Like outlet boxes, switch boxes can be mounted on a wall or ceiling and come in various sizes. They must also be properly sized and rated for the amount of current they will be carrying.
  • Ceiling boxes: These boxes are used to hold light fixtures, ceiling fans, and other electrical devices that are mounted on the ceiling. They come in various sizes and shapes, and they must be properly rated for the weight of the electrical device being installed.
  • Load centers: These boxes, also known as breaker boxes or panel boxes, contain the main circuit breaker or fuse for an electrical system. They are typically mounted on a wall and provide a central location for distributing electricity throughout a building. Load centers come in various sizes to accommodate the number of circuits and devices in a building.
  • Floor boxes: These boxes are used to provide electrical outlets on the floor of a building. They are typically installed in areas where it is difficult to run electrical cables through walls or ceilings, such as in offices with raised floors. Floor boxes come in various sizes and shapes and must be properly rated for the amount of current they will be carrying.
  • Weatherproof boxes: These boxes are designed for outdoor use and are used to hold electrical outlets, switches, and other devices that are exposed to the elements. They are typically made of metal or plastic and have a gasket or seal to keep moisture out.

In addition to these common types of electrical boxes, there are also specialized boxes for specific applications, such as fire-rated boxes, which are used in areas where a fire-resistant barrier is required, and explosion-proof boxes, which are used in areas where flammable gases or vapors may be present.

Regardless of the type of electrical box being used, it is important to ensure that it is properly sized and rated for the electrical load it will be carrying. Using the wrong type or size of the electrical box can result in electrical fires, shocks, or other dangerous situations. It is also important to follow all local building codes and electrical codes when installing electrical boxes to ensure the safety of the electrical system.
