I know this question is strange, but does anyone "correctly know how to use those green ground clips on standard steel switch/outlet boxes?" If you were holding the clip and the opening is to the right, where does the wire go in relation to the opening? Do you just slide the wire down through the left-side opening and then clip it to the box, or do you have to feed it someway through the side and then end. This is a very hard question to type, very awkward so I hope someone knows what I'm talking about. I always use screws, but was asked why and probably because I never thought of them or saw them as really being safe.
