Adaptive arc fault detection and smart fusing system

An adaptive fusing electrical circuit (circuit) including a power supply and an electrical load drawing an electrical current therethrough. The circuit includes a current detector that measures a current level through the circuit. An interruption switch, which is normally closed, is electrically coupled to the electrical load and the current detector having an open state and a closed state. A controller is coupled to the power supply, the current detector, and the switch, the controller monitors the current level and a first circuit parameter of the electrical circuit. The controller interrupts the electrical current by switching the interruption switch from the closed state to the open state when the current level and the first circuit parameter are outside corresponding guard bands.
