What is a Junction Box?
Electrical junction boxes are devices that contain the wiring junctions or intersections that allow the wiring in the home or public building to interface with the main power supply provided by a local utility. The presence of the junction box is generally regarded as both practical and more esthetically pleasing than a bunch of exposed electrical wires. While the exact configuration for electrical junctions containers of this type vary slightly, there are a few basic elements that are common to all junction box designs. For many people, the main purpose of a junction box is to conceal the electrical junctions from sight. Usually constructed with the use of metal or hard plastic, the general appearance of a junction box is either a square or rectangular design. A door on the front of the box allows access to the interior. The door may be recessed in the front of the junction box, or the entire facing may swing upward or downward to allow access to the junctions within the device. In ma
