ABSTRACT:
A circuit breaker operating handle formed from a plastic composition includes a handle access post and a curvilinear handle skirt. A pair of opposedly positioned detent members are integrally-formed on the surface of the handle skirt opposite the handle access post. The detents correspondingly engage the top planar surface of a U-shaped handle yoke which interfaces with the circuit breaker operating mechanism. The circuit breaker operating handle is robotically down-loaded onto the handle operating yoke prior to attachment between the handle yoke and the circuit breaker operating mechanism.
