Stacked electrical system for connecting a printed circuit board to a busbar

An electrical system, comprising:

• a busbar assembly including first and second bush ars, wherein a first contact tab extends from the first busbar, and a second contact tab extends from the second busbar, wherein the first and second contact tabs include first and second interface ends, respectively, within a common plane;
• and
• a connector assembly including a housing that retains first and second electrical contacts, wherein each of the first and second electrical contacts is a one-piece unit, wherein the first electrical contact includes a first contact terminal and the second electrical contact includes a second contact terminal, wherein the first contact terminal defines a first interfacing space and the second contact terminal defines a second interfacing space, wherein the first and second interfacing spaces are aligned with one another, and wherein the first and second interface ends are configured to mate with the first and second contact terminals within the first and second interfacing spaces, respectively.
