Technical Examples

A control system for a power distribution system includes electrical operators each of which has an open input, a close input and an operator member adapted to cooperate with a corresponding circuit breaker operating mechanism. Each operator member responds to the corresponding open input to actuate the operating mechanism and open the corresponding circuit breaker, and responds to the corresponding close input to actuate the operating mechanism and close the corresponding circuit breaker. A control circuit includes an input for a normal power source, an input for an emergency power source, open outputs electrically connected to the open inputs of the corresponding electrical operators, and close outputs electrically connected to the close inputs of the corresponding electrical operator. The control circuit delays one or more of the close outputs or inhibits one or more of the close outputs after a transfer switch output switches to the emergency source.
