Electrical loads are powered by one of several different power sources through a selector switch. A monitoring circuit monitors the different power sources to sense a change of state, that is, power up or shut down. Such a change indicates that the selector switch is likely to be operated to select a new power source. The monitoring circuit shuts down certain loads to limit current surges when the new power source is connected.


[ What is claimed is:] [1.] A power circuit comprising:first and second power sources;a power bus connected to provide power to loads;a transfer switch for selectively connecting the power bus to one of the power sources;a controlled load connected to receive power from the power bus;a controller connected to control power supplied to the controlled load from the power bus; anda monitoring circuit including first and second sensors for monitoring the first and second power sources, respectively, wherein the monitoring circuit is connected to cause the co...
