Abstract
A ground overcurrent control system includes ground circuit with a first section and a second section. The first section is electrically connected to a ground member of an electrical connector and the second section is electrically connected to a ground reference. A switch element is positioned between the first section of the ground circuit and the second section of the ground circuit. A controller is configured to determine the current within the ground circuit while current is passing through the switch element and, upon the current exceeding a current threshold, the switch element is modified to an open condition. Upon determining that the voltage between the first section of the ground circuit and the ground reference is less than a voltage threshold, a command is generated to modify the switch element back to a closed condition.
