We recently discovered that our Trail Runner's AC system is running on a 15 amp breaker. Last year we thought all the cottonwood seeds were clogging the cois and tripping the system, but when we cleaned the system this year, the AC breaker was still tripping. Looking at the breaker panel revealed the 15 amp breaker triping and not the 20 amp breaker as listed on thr panel. When I shut of the 20 amp breaker everything in the outlets go off. Seems to me an assembly error.
