Abstract
A load management control apparatus with an improved duty cycle operation has a programmed means to control the off time for a selected interval of time for several loads. The total percentage of off time of the loads being controlled is summed and the total integer is used by a sequential operational means to maintain that number of load off at all times even if loads which are off on demand limit control are included to make the number.
