Yes I have the tandem 30A/20A breaker. The 30A side carries all 120V incoming from the power cord, while the 20A supplies the rooftop A/C unit. Bad arrangement really, because that one breaker assembly carries nearly the entire load in both directions, and it was getting very hot. My panel has a couple of spare slots, so today I bought a new Eaton BD2020 breaker at Lowes. I plugged it into the slot furthest away from the 30/20 breaker, and moved the wire for my A/C to the new breaker. Works great now. All breakers are running cool, and I now have a couple of spare breakers in case I ever need to run something temporarily.
