Abstract

A junction box includes a first cover plate that covers a first open side defined by a main body, and a second cover plate that covers a second open side defined by the main body. The second cover plate includes a mounting pad to attach an electrical component thereto. The electrical component is disposed in an inner cavity defined by the main body when the second cover plate is in a closed position. Further, the junction box includes a fastening device that retains the first cover plate and the second cover plate in the closed position and operates without interfering with a mounting structure in which the junction box is disposed. Furthermore, the junction box includes chamfer walls and wire traps disposed thereon to receive and pass electrical wiring cables into the junction box therethrough.
