I broke the tab off without much effort trying to tighten it. I usually put 2 wrenches on the bolt to prevent something like you do with the copper fitting, but the width of the bottom nut is too thin to allow for this. What I liked about the switch is that the cable exit plates can be moved if you change your mind. It would work if the plastic was stronger. BTW, the nut is 5/8" and I was trying to fit a #2/0 spade lug with a 3/8" hole.
