1. A virtual branch circuit system for an electric vehicle supply equipment (EVSE), comprising:
a current sensor disposed in operative communication with circuit wires of a plurality of circuits of a virtual branch, the current sensor disposed between a plurality of circuit breakers and a plurality of respective loads, wherein at least one of the plurality of loads is not an EVSE, wherein the current sensor is configured to sense a virtual branch total current comprising a total current of all non-EVSE loads on the virtual branch; and
a control module operatively connected to the EVSE and configured to control a maximum EVSE current based on the virtual branch total current to maintain the virtual branch total current at or under a maximum branch current threshold.
