Abstract: A junction box that facilitates the connection of a conductor to a component located within the box. The box comprises a rear panel, side panels extending around the periphery of the rear panel and a front closure panel spaced from the rear panel. A pair of apertures are located in opposite ones of the side panels to allow passage of the conductor through the box. The side panels are formed in two sections with the sections meeting on the center line of the aperture. One section is attached to the rear panel and the other section is attached to a further side panel that extends between the opposite ones of the side panels. The further side panel is releasably connected to the rear panel by a releasable fastening positioned to be accessible upon removal of the closure panel.
