1. An energy management system for controlling a plurality of electrical loads, the electrical loads having first, second, and third priorities of use, respectively, comprising:

  • first sensing means for sensing currenrt flow in the first electrical load and for providing an output signal in response thereto;

    second sensing means for sensing current flow in the first electrical load or the second electrical load and for providing an output signalin response thereto;

    first interrupting means for interrupting current flow in the second electrical load, the first interrupting means being electrically connected to the first sensing means and being actuated upon receiving an output signal from the first sensing means;

    second interrupting means for interrupting current flow in the third electrical load, the second interrupting means being electrically connected to the second sensing means and being actuated upon receiving an output signal from the second sensing means; and

    a step-down transformer, the output side of the transformer being electrically connected to each of the sensing means and the interrupting means.
