ABSTRACT:
A circuit breaker switchgear housing device having a stab positioning system whereby a draw-out circuit breaker having separable contacts is contained in the switchgear housing. A stab positioning system is utilized so as to precisely locate stabs so that a circuit breaker having contact clusters which are electrically attached to the circuit breaker contacts make accurate and uniform contact with the stabs. The stabs are generally a rectangular-shaped bar with one of the ends being rounded off. Cut into two sides of the stab and opposing each other are notches. The stab is inserted into a retainer or positioning washer which has a bayonet-type lock opening into which the stab is inserted and rotated 90.degree., thereby prohibiting axial movement of the stab with respect to the washer. A retainer or positioning washer having an opening slightly larger than the stab cross-section is used to rigidly position an inserted stab, prohibiting rotational movement with respect to the opening in the stab. An insulating partition which is rigidly attached to the switchgear housing, facilitates the positioning and attachment of the two positioning washers containing the stab. The positioning washers are separated by a ledge contained in the insulating partition.
