Bussed electrical center

A bussed electrical center includes an electrical-assembly and a single fastening feature. The electrical-assembly includes a lower-housing, a printed-circuit-board, an upper-housing, and electrical-devices. The lower-housing engages an outer-housing that retains electrical-connectors having a plurality of electrical-terminals. The printed-circuit-board has a plurality of corresponding-electrical-terminals configured to mate with the plurality of electrical-terminals of the electrical-connectors. The electrical-assembly defines a guide-hole that passes through the upper-housing, the printed-circuit-board, and the lower-housing, wherein the guide-hole defines a shoulder in the upper-housing. The single fastening feature consists of one first-fastener element positioned within the guide-hole that has a flange and a shank. The shank is operable to engage one second-fastener element in the outer-housing. The flange engages the shoulder, wherein the electrical-assembly is drawn into the outer-housing when the first-fastener element and the second-fastener element are tightened together to mate the electrical-terminals with the corresponding-electrical-terminals.
