Abstract: A terminal block having a front face and a rear face is provided. An array of counterbores are formed in the terminal block which extend between the faces and define abutment surfaces therein. The counterbores are positioned so that the portion of greater diameter is adjacent the rear face. The counterbores are adapted to receive terminal contacts via the rear face so that the female end of the terminal contacts rest near the front face. Grooves are formed in the rear face which connect selected counterbores. The selected counterbores received one type of terminal contact having a male end of reduced length. A face plate having apertures formed therein is removably secured to the rear face. The apertures are aligned with only the counterbores receiving another type of terminal contact having a male end which extends beyond the rear face to allow the male ends to pass. Ground wires are passed along the grooves and contact the male end of the one type terminal contacts.

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.
