A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. The housing has a cover securable to a base, with the cover including a downwardly-facing abutment portion. An electrical terminal is releasably disposed within the base and has a tab that abuttingly engages the abutment portion of the cover when the cover is secured to the base. The base also includes channels formed in the sides of the base, and the electrical terminal includes sides that insert into the channels and that include rib portions that frictionally engage the channels upon insertion. The base also includes tapered sides, with the electrical terminal sides being tapered in order to follow or mirror the tapered sides of the base.
