Abstract: A buss bar for electrically coupling a plurality of electrical terminal posts or wires including a generally tubular elongated body formed of electrical conducting material which defines a slot extending substantially along the entire lateral side of the body, a plurality of holes or apertures arranged in pairs such that one of the holes of each pair is positiond in the upper surface of the body and one of the holes of each pair is positioned in the lower surface of the body to allow one of the terminal posts to be positioned through each of the aperture pairs, a groove or other similar indentation along the opposite side of the body from the slot and extending inward into the center of the body such that the interior surface of the groove is in a position of abutment with a terminal post positioned through the upper and lower holes, the amount of lateral pressure exerted by this interior pressure exerting surface upon the terminal posts being variable proportionally in response to the width of the slot locat
