Welcome, Pilgrim! I do NOT like those two-in-one Breakers. Even without being an electrical engineer, it doesn't make sense how (at least our) a Load Center is wired.
It has several 15/15 tandems, then a 30/20 where 30 feeds power INTO the whole breaker buss and feeds the A/C with its own 20 side. How can that NOT help overheat a thermal breaker?
I've replaced ours twice. Wonder how much it'd help to make the Main breaker a 30/15 and some other Branch a 15/20 to at least divide the load up.
I work in DFW, Texas and it is one of the HOTTEST areas of the country. I have never had a problem with a combo breaker set up. I have worked on thousands of AC units over the years and I rarely have to replace a breaker from being worn out or Heat related. I usually replace due to customer wanting it done, not because it is defective. Doug
