A common mistake people make is, they think a Breaker will trip when they overload the supply system. In effect, the current drops as the amp load increases and the Heat build up causes electronic items to then fail. The ATS can handle 30 and 50 but cannot handle any type excess amp/current problems.

I am confused by this. What do you mean by "the current drops as the amp load increases"? Those are precisely opposite statements; it is akin to saying that speed decreases as mph increases.

The sole purpose of a circuit breaker or fuse is to cut the power in the event of an overload (overcurrent) situation. If it does not do that, it is dangerously defective.

not necessarily. Breakers trip by thermal energy on a bimettalic strip. If heat is absorbed by other means such as too small of a gauge wire or cord, the braker never sees the heat even though it is supplying far over its rating. It's not unusual to see 30A RV outlets melt to the plug because the load is using 40-50-60 amps but the 30a cord is shedding the heat instead of the breaker seeing it.

Regardless, I still don't see where the OP did anything wrong. The transfer switch needs replaced, simple as that. They are junk anyway. Ours on our 5er was recalled twice.
