I didn't use the adapter since the cable has a bottom entry. I understand why you think that trimming one wire isn't a good idea and I was considering the same question as I decided to do it. However, consider that these connections are just the wire being pinched beween 2 metal plates at the terminal. The surface area of wire contacting the plates likely does not change at all based on what I did. There is only a fraction of any wire in contact to the metal plates in any terminal.

Hrm yeah. I have know idea what the practical implications of this might be. You may be right?

Perhaps using ferrules might be a good idea and help in this situation?
