Abstract
A miniature molded case circuit breaker is adapted for use with load conductors having ring lug terminations by extending the circuit breaker load terminal conductor through the terminal recess and beyond the molded housing. An adapter includes an insulative shield member having an open slot in which the load terminal conductor terminates for connection to the ring lug on a load conductor. The adapter further includes an insulator which seats snugly in the terminal recess of the housing and through which the load terminal conductor extends. A bifurcated neck on the insulator extends through an opening into the shield member. The shield member is secured to the circuit breaker by projections which snap into grooves in the neck portion of the insulator and a cantilevered resilient finger which engages a catch on the molded housing.
