I decided the move my AC circuit which was on the 20 amp breaker on the 3020 to the end of breaker panel. I wanted to move a circuit that didn't generate heat to the one next to the 30 so it meant shuffling a couple of wires around.
I did replace my 3020 breaker last year since it had popped so many times trying to run the AC together with the 110v water heater. I wish I could remember how I did it. I remember the tab. I think I had to remove it.
