This was a multiple-choice question, but I am assuming that you meant
"Yes, you can run 162A through this puppy by paralleling all the
contacts". If I'm wrong, please let me know before I burn my house

I have decided to run both lines through the relay regardless of what's
hot or not. That way, I won't have to worry about anything and I will still
be able to safely switch 81A...more current than I'm going to be able to
safely suck out of my 50A wall socket anyway. I will also be able to get
120V from the 240V outlet by only using one hot side.
