Circuit Breakers Tripping? Find out why they typically trip.

The primary reasons for circuit breakers tripping include: Overload: Description: An overload occurs when the electrical demand on a circuit exceeds its capacity. For example, plugging in too many high-wattage appliances into a single circuit can cause it to overload. The circuit breaker trips to prevent overheating and potential fire hazards.

There was one eaton 20a normal breaker, one eaton 20a gfci breaker, and the rest were eaton afci breakers (green ones). Yesterday we swapped out 2 of the afci breakers with new ones (same kind). We also eliminated a few on lighting circuits and put in non-afci breakers to test things out. So 7 breakers tripped twice at 10pm last night.
