Abstract: Circuit breakers having a cover that includes a medial segment with an aperture for a switch handle. The medial segment merges into a line side segment having at least one channel overlying a lug compartment. The at least one channel has an inner end portion overlying a lug access path to the lug compartment. The circuit breakers also include at least one gas-blocking member coupled to the at least one channel.

Abstract: A maintaining system is for an electrical switching apparatus. The electrical switching apparatus includes an electrical switching apparatus cover having an edge portion defining a thru hole. The maintaining system includes a test port cover member and an insert. The test port cover member is structured to be coupled to the edge portion. The test port cover member has a plate portion and a pair of opposing leg portions extending from the plate portion. The leg portions are structured to extend into an interior of the electrical switching apparatus and engage the electrical switching apparatus cover. The insert extends through the plate portion. The insert is structured to engage each of the leg portions in order to prevent the leg portions from deflecting toward each other, thereby maintaining the test port cover member on the electrical switching apparatus cover.

Abstract: A retention system is for an electrical switching apparatus. The electrical switching apparatus includes a frame having a number of slots, a cover coupled to the frame, an electrical component enclosed by the frame and the cover, separable contacts enclosed by the frame and the cover, and an operating mechanism to open and close the separable contacts. The retention system includes: at least one bundle of wires having a plurality of individual wires extending through a corresponding one of the number of slots to be electrically connected to the electrical component; and at least one restriction mechanism each including an insulative sleeve surrounding a corresponding one of the at least one bundle of wires, and a blocking member connected to the insulative sleeve. The blocking member engages the frame to prevent undesired movement of the individual wires with respect to the corresponding one of the number of slots.
