The Junction box we deal in works as the common meeting spot for many electrical wires. It is really needed to protect hot, grounding and neutral electrical wires. The box has many other secondary functions as well. Basically, this is a code requirement which is made to prevent electrical accidents and fires. Junction box must be installed in a correct way so as to allow high level of safety. It must be used to do away with many potential sparks. Also, it can do away with the problems of low-priced box extension. This is suited for metal or plastic enclosure. In a way, it can be used as the frame for wiring connections.
