Abstract: An electrical panel having an extendible lower portion. The panel has an overall size equivalent of an ordinary panel. However, approximately one third of the panel is cut off and removed. This separate bottom piece is then replaced and held in place with thumbscrews. Thus, when stored, the lower portion is pushed up against the bottom of the cut portion. This reduces the overall length of the panel. The wires can then be placed into the panel and the panel can be secured inside the wall without having to cut a larger hole. Once the upper portion of the panel is secured, the lower portion can be extended downward until the opening is fully filled. The thumbscrews can be locked in place and the fully extended panel is then ready for wiring. A bonding jumper is used to ensure a proper ground between the two portions. Other than the bonding jumper and locking the extended panel into place, the panel is then made up as usual.
