ABSTRACT:
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.
