Anyone have some suggestions on how to properly terminate larger wires in panels? I'm faced with a 200A panel but we are sub feeding a seperate 100A panel on the second floor of the house. 3C #2 AL NMD cable is what we used. The problem now is that the neutral busbar has all the same size holes to terminate and they are all only good for up to #4. The panel is an Eaton Cuttler Hammer.
