A bused electrical center and a method for its construction. The bused electrical center includes a plurality of bus bars, which are housed between a bus bar housing and a filter housing, a filter device and a plurality of interface terminals that couple leads on the filter device to isolation tabs formed on the bus bars. No solder is employed to electrically or mechanically couple the interface terminals to the leads or to the isolation tabs such that the interface terminals are the sole means for electrically connecting the isolation tabs and the leads.
