1. A branch circuit monitoring system comprising: a first collection device configured to receive alternating current (AC) signals indicative of a measured current value in at least one branch circuit of a first plurality of branch circuits and convert the alternating current (AC) signals indicative of the measured current value in the at least one branch circuit of the first plurality of branch circuits from the alternating current (AC) signal to a direct current (DC) signal indicative of the measured current value; a second collection device configured to receive alternating current (AC) signals indicative of a measured current value in at least one branch circuit of a second plurality of branch circuits and convert the alternating current (AC) signals indicative of the measured current value in the at least one branch circuit of the second plurality of branch circuits from the alternating current (AC) signal to a direct current (DC) signal indicative of the measured current value; and a panel processor in communication with the first and second collection devices configured to receive the plurality of DC signals via an input circuit of the panel processor, the input circuit comprising multiplexers for receiving the first plurality of DC signals from the first collection device and the second plurality of DC signals from the second collection device, the panel processor configured to store in a local memory a plurality of data structures comprising the measured branch circuit current data values for said branch circuit along with a timestamp associated with a time at which the currents were measured.
