- A junction box is an electrical box used to run multiple conductors in two or more directions to bring power to various electrical devices.
- Junction boxes are required to be installed so they are always accessible;
- Never install a junction box in a concealed wall or ceiling space where is can not be accessed in the future.
- Wire connectors (wire nuts) and wire lengths take up a lot of space in a box. Because square boxes provide maximum volume for multiple conductors and connectors they are most often used as a junction box.
