1. A contactor system comprising:
a contactor actuator that causes an input bus bar to be electrically connected to an output bus bar;
an actuator control element that controls operation of the contactor actuator, wherein the actuator controller includes an input and an output;
a connection that includes two inputs configured to receive signals from two or more controllers and provide one control signal to the input of the actuator control element; and
a relay coupled between the output of the actuator control element and ground that disrupts the signal from passing through the actuator control element when commanded by any of the one or more controllers.
