An electrical distribution box including a bus bar with a quick connect assembly for engaging or disengaging wiring. The bus bar housing defines an interior chamber and includes a wall defining a plurality of holes and release ports therein A space bar within the chamber includes a plurality of spaced-apart fixed contacts and spring contacts. Each spring contact includes an arm that moves towards or away from the fixed contact and is partially aligned with one hole and one release port in the housing. The spring contact moves from an at rest position by inserting a wire through one of the holes. The spring contact locks the wire between itself and the fixed contact. The wire is release by inserting a tool through the release port and applying a linear force to the spring contact, thereby rotating the spring contact away from the fixed contact and releasing the wire.
