This device is the modification of my patent number 9293903, date: 03/22/2016. A convenient electrical connector box will be used for repairing a broken household electrical line, or connecting an existing electrical line to new multiple locations. It provides all components in a package for completing a task. The package will include an electrical connector unit, a cover for enclosing the entire electrical connector unit, screws for securing the electrical connector box on a building structure, and screws for attaching the cover to the electrical connector unit. The electrical connector box can be mounted on a building structure in an open space such as the attic, crawlspace, or outer wall of a frame of a building or similar structure.
