In one aspect, the invention provides a system for protecting a plurality of circuits including a plurality of circuit protective devices wherein each circuit protective device includes a respective nominal current rating. According to one embodiment, the system includes current sensing circuitry configured to measure a current of each circuit protective device; and a controller configured to receive each of the measured currents. According to one embodiment, the controller is further configured to determine a ratio between a total current being carried by all of the circuit protective devices combined and a total nominal current rating of all of the circuit protective devices combined and employ the ratio to determine a modified nominal current rating of each circuit protective device, respectively. In a further embodiment, the controller is configured to generate an output signal to isolate a selected circuit selected from among the plurality of circuits based on the modified nominal current rating of the circuit protective device included in the selected circuit.
