This is not safe or normal right?
I'm in the process of replacing the outlets around my house, originally for aesthetics and now for safety as well (I heard backstabbing isn't good, seems that's how they were all done here). This outlet in particular has 3 wires going to each side, two backstabs and one just sorta laying on a screw. I have never seen anything like this. Should I pigtail two on each side together or is there something special I should know?
