1. A load shed module configured to be connected in series between a power source and a load, the load shed module comprising:

  • an input configured to receive a first electrical connection from the power source;

    an output configured to provide a second electrical connection for the load;

    a switch operatively connected in series between the input and the output, wherein the switch receives a control signal to selectively open and close the switch;

    a sensor configured to generate a feedback signal corresponding to an alternating current (AC) voltage present at the input;

    a priority selector operable to generate a priority signal for the load shed module,a controller connected to the sensor to receive the feedback signal, connected to the priority selector to receive the priority signal, and connected to the switch to supply the control signal, wherein the controller is operable to;

    determine whether the power source is a utility power source or an alternate power source as a function of the feedback signal,compare the feedback signal to a threshold when the power source is the alternate power source,generate the control signal to open the switch when the feedback signal exceeds the threshold for a first predetermined time, andgenerate the control signal to close the switch when the power source is the alternate power source and when a second predetermined time has passed, wherein the second predetermined time is selected as a function of the priority signal.
