Abstract
Abstract A terminal strap is formed having turned down side edges and a turned down frontal tab for supporting the strap in spaced relation to the floor of a terminal recess formed in the molded case of a circuit breaker. An inverted U-shaped lug is slideably received on the strap with upwardly formed flanges engaging the turned down side edges. Lips formed on the deflectable sidewalls of the terminal recess retain the lug in place. The strap is also formed with a tapped hole to accommodate a bolted joint binding head screw or wire keeper in lieu of the lug.
