A two-piece bus bar electrically couples a printed circuit board to a power supply. The power supply is mounted to a chassis. A power supply bus bar extends from the power supply, defining a power supply bus bar plane. A first printed circuit board is mounted to the chassis and oriented in a plane that is not parallel with the power supply bus bar plane. A first printed circuit board bus bar extends from the first printed circuit board. At least one of the power supply bus bar or the first printed circuit board bus bar includes a bend that creates a parallel relationship between a mating portion of the power supply bus bar and a mating portion of the first printed circuit board bus bar. A first fastener couples the mating portions of the bus bars together. A second printed circuit board may be mounted to the chassis and oriented in a plane at right angles with the power supply bus bar plane. A second printed circuit board bus bar extends from the second printed circuit board and includes a 90-degree bend and a 180-degree bend such that a mating portion of the second printed circuit board bus bar is parallel with the power supply bus bar plane. A resilient conductive member having a convex surface is disposed within a channel formed in one of the bus bars to enhance electrical contact between the bus bars. Shock and short-circuit hazards are reduced with a removable insulating shield.
