DCFirst Claim
1. A prefab bracket and open back junction box assembly comprising:
- an open back junction box having an open front for mounting an electrical device and plaster ring, and an open back comprising a single opening about the same size as the open front and opposite the open front for accepting a detachable rear cover plate;
a plaster ring attached to the open back junction box;
a mounting bracket sandwiched between the plaster ring and the junction box;
an electrical device attached to the plaster ring;
a protective cover over a face of the electrical device;
first ends of electrical leads attached to the electrical device;
labels proximal to a second end of each electrical lead identifying each lead;
wire nuts residing over free ends of each electrical lead; and
a detachable rear cover plate attached to the back of the open back junction box over the open back while leaving the second ends of the leads inside the junction box and unattached.

Abstract
A bracket and junction box assembly and method allows simplified wiring at a prefab production facility and at a construction site. A junction box including a detachable and reattachable rear cover plate is pre-assembled with a plaster ring, electrical device, and leads attached to the switch or outlet, at a prefab facility. A Metal Clad (MC) cable may be attached to the junction box and wires carried in the MC Cable may be connected to the leads. A mounting bracket is generally sandwiched between the junction box and the plaster ring for mounting to framing members at the construction site. Following assembly at the prefab facility, the prefab junction box is shipped to the construction site where the bracket and junction box assembly is mounted to framing members. Connections to wires carried by MC Cables are then facilitated by removing the rear cover plate to access the interior of the junction box.
