Abstract: An interconnect box between a utility meter and a main service panel having at least two grid electrical inputs from the utility meter; at least one grid neutral input from the utility meter, wherein the grid electrical inputs and the grid neutral inputs are combined to provide a combined grid stream; at least two external electrical inputs having circuit breakers for each of the at least two electrical inputs; at least one external neutral input; at least one shorting block used to merge together two of the at least two external electrical inputs and one of the at least one external neutral inputs to provide an external merged stream; a central computing unit receives and utilizes power from at least one of the combined grid stream and the external merged stream to generate power and source voltage on energy metering.
