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.
