A monitor circuit that monitors power delivered by an electrical utility or other source to a consumer. The device may be located at or near an entry point, such as near an electrical meter. The device senses a material change in voltage, and terminates power to the consumer until normal voltage is restored. The device automatically resets when normal voltage is restored, without need for a service call.

A system for a vehicle includes a converter configured to, responsive to a first signal from a first adaptor indicating a first plug type having a first electrical parameter configuration, output power to the adaptor according to the first electrical parameter configuration, and responsive to a second signal from a second adaptor indicating a second plug type having a second electrical parameter configuration, output power to the adaptor according to the second configuration.

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.
