An interface system may be used to connect an electrical device to an electrical bus. The interface system may include a first end and a second end in electrical communication with the first end. Where the interface system is used to connect an electrical device to an electrical bus, the first end may be connected to the electrical bus and the second end may be connected to the electrical device. The interface system may also include a reverse current blocking circuit configured to block current from flowing from the second end to the first end. Additionally, the interface system may include a discharge circuit electrically connected between the first end and the second end for discharging the blocked current.
