1. A system for monitoring and controlling a power distribution system that has a plurality of circuit branches for providing power to a plurality of devices, the system comprising:

  • a control module configured to;

    control a first device on a first circuit branch to increase power draw to operate at a predetermined percentage of maximum power, wherein the predetermined percentage of maximum power is less than 100%;

    detect a first value for a characteristic;

    of power provided to the first circuit branch using a first power monitoring device;

    control a second device on a second circuit branch to increase power draw to operate at a predetermined percentage of maximum power;

    detect a second value for a characteristic of power provided to the second circuit branch using a second power monitoring device;

    add the first value to the second value to obtain a total value;

    compare the total value to an overload value to detect an overload condition; and

    indicatean alarm condition when the total value exceeds the overload value.
