CIRCUIT BREAKER LINE TERMINAL SCREW RETAINER ABSTRACT OF THE DISCLOSURE A composite line strap is used with molded case circuit breakers to support the circuit breaker station- ary contact and to retain the circuit breaker line ter- minal screw. The fixed contact is welded to the line strap within the breaker at a first end and the line terminal screw is attached to the opposite end of the line strap by a through-hole in a spring-steel retainer which extends partially within the circuit breaker. The line terminal screw is tightly held within the through- hole of the retainer at the first end and the retainer itself is trapped between the bottom of the circuit breaker case and the line strap at the opposite end of the line strap.
