An electrical system includes (1) a distributed power source device structured to generate: (i) AC power, and (ii) a signal indicating an amount of current being produced by the distributed power source device, and (2) a circuit breaker having set trip characteristics coupled to distributed power source device, wherein the circuit breaker is structured to receive the signal and adjust the set trip characteristics (e.g., the trip curve) based on at least the signal from the distributed power source device.
