Types of Electrical Boxes
Electrical boxes, also known as junction boxes, enclose wire connections. They help protect against short circuits, which can cause fires. This guide describes the different types of electrical boxes, their materials and their applications. They come in many shapes and sizes to fit wherever you need them. Learn about the differences so you can feel confident that you’re choosing the right box for your project.
IMPORTANT: The National Electrical Code (NEC) and local building codes regulate the types of electrical boxes allowed in certain applications, as well as how they’re installed. Per their requirements, electrical boxes must be covered with matching electrical box covers. You can’t cover them with drywall, paneling or other wall coverings. The box also needs to have enough space for the conductors inside.
Check with your local building inspector before you start any electrical project and obtain the required permits. When you’re done, always have your work inspected for compliance with local codes. This is to ensure that the electrical boxes have been safely installed.
With a bit of preparation, you can add electrical boxes to your home. Just decide on the location and choose the right junction box for the job. Once you have power available where you need it, you can update your living space. Add new lights, ceiling fans or other appliances to enhance your decor.
