1. For use in a home or business which receives single or multiple phase A.C. electric power from at least a first power source, the A.C. electric power having a standard frequency and voltage and powering a group of loads in the home or business, a load coupler device operating to disconnect one or more loads to prevent or relieve an overload of the power source which is supplying power thereto, the load coupler device comprising:
a) a contactor comprising one or more each of a control connection for opening and closing the contactor, a line connection for receiving A.C. electric power from a power source, and a load connection for supplying power to a corresponding first load when the contactor is closed,
b) a power supply circuit having an input coupled at the line connection to the electric power and an output providing lower voltage power to power a processor circuit,
c) a user input circuit coupled to the processor circuit, the user input circuit to receive inputs from an installer thereby allowing configuration of the load coupler device by the installer when it is installed to operate with the first load,
d) the processor circuit coupled to the line and control connections of the contactor and executing a program whereby via the connection or sensor coupled to the line connection the processor is responsive to the amount of total load on the power source and one or more of voltage, current or frequency of the electric power supplied at the contactor line connection to cause a load shed by opening the contactor to either relieve an actual overload or prevent a potential overload of the power source, or both, and following the load shed after at least a known time period the processor closes the contactor to resupply power to the first load, the known time period responsive to the configuration of the load coupler.
