Abstract: An enclosure (10) contains an APU (12) and an electrical distribution system (14) to form a self-contained module that can be mounted at any suitable location on a truck's exterior, eliminating significant portions of the wire/cable routing that would otherwise typically be required.

Abstract: The catch for an auxiliary power unit cover comprises a bracket which has an opening therein sized and configured to receive shore power receptacles of the unit within the opening, the bracket being engaged to and extending outwardly of the cover, and over the receptacles, such that the cover cannot be removed while shore power lines remain engaged within the receptacles therefor.

Abstract: A bus bar (20) for grounding multiple wires/cables (74) in an engine compartment of a truck. The bus bar has four threaded studs (24, 26, 28, 30) extending from an outer face of a plate (22) and two circular rings (32, 34) on an opposite face spacing the plate from the dash panel (60). An array of multiple through-slots (24A, 26A, 28A, 30A) in the plate surround each threaded stud with the through-slots arranged in unique circumferential locations about the respective stud to provide unique circumferential locators for a tab (78) of an eyelet terminal (76) on a wire/cable (74) to locate the terminal in a correspondingly unique circumferential location about the threaded stud when placed thereon and in contact with the plate preparatory to tightening of a nut (80) that, when tightened, forcefully holds the terminal against the plate.
