    Patent number: 4421992
    Abstract: Apparatus for controlling the peak load demand of a home or business establishment by preventing the simultaneous application of electrical power to first and second electrical loads is disclosed. The apparatus includes first and second sensing means (16, 18), one each of which monitors each of the first and second electrical loads (12, 14) respectively for determining when the first and second electrical loads (12, 14) are demanding electrical power. The sensing means (16, 18) then provide sensing signals to a combining means (24) which receives the sensing signals, or representations of these sensing signals. Combining means (24) provides a timer start signal to timer (28) when the sensing signals or representations of these sensing signals are present at combining means (24).
