The base of that contactor is not a conductor nor a jumper.
I am forced to read the words of the code and enforce them. I can't make things up.
I also wonder how much evidence there is that these provide a less than satisfactory mounting strength.
I asked before, how do you attach boxes to metal studs?
I see them using self drilling thread forming screws.
There is certainly a lot more direct force applied to a receptacle box with plugging and unplugging than you have with a contactor making and breaking. In Florida that is also how you bond the steel studs.
