I recently added a dual 20 amp breaker to the Montie's panel box so I could add an outlet in the basement. Everything went fine with one exception. The panel box uses a small plastic wedge to hold in wires, and I have no idea where to get one of these. In fact, I don't even know what to call it. The local RV counterman looked at me like I was a three headed unicorn when I asked him if they had any "little plastic wedges that hold the 110v wires in the panel box" and gave me his standard "we don't carry those" answer.
Any ideas????
