The 2nd floor bedroom circuit tripped turning off window A/C unit in child’s room. I found that this circuit also controlled room underneath bedroom and lights in the basement corner. The A/C unit is 1000W and is on a 15 amp breaker. Circuit breakers are all new Cutler Hammer CH breakers. I found that the circuit is slightly over loaded. This size of equipment should have a dedicated circuit if other devices (ceiling fans, computers) want to be ran at the same time.
