Abstract

A pair of adapter blocks, each arrangeable in two physical orientations, provide an interface between an electrical outlet receptacle block and four different electrical circuits of a power distribution block. Each adapter block has terminals on one end for engaging the receptacle block, including one terminal disposed on the centerline of the adapter and a pair of terminals disposed on opposite sides of and equidistant from the centerline. Furthermore, each adapter has terminals on an opposite end for engagement with the power distribution block including terminals disposed on opposite sides of the centerline and offset from the centerline by different distances. Each receptacle block may be changed from one physical orientation to another by rotation about the centerline. One of the blocks, in a first physical orientation, connects a first positive terminal, a first neutral terminal, and a ground terminal of the power distribution block to the outlet receptacle block and in a second orientation connects a second of the positive terminals, a second of the neutral terminals and a ground terminal of the power distribution block to the power receptacle block. Similarly, the second adapter block in a first physical orientation connects a third positive terminal, a third neutral terminal, and a ground terminal of the power distribution block to the outlet receptacle and in a second physical orientation connects a fourth positive terminal, a fourth neutral terminal and a ground terminal of the power distribution block to the outlet receptacle block.
