Abstract: A ground conductor monitoring device, having: at least one ground conductor connection which is designed to connect a ground conductor potential, at least one first potential connection which is designed to connect a first electrical potential which differs from the ground conductor potential, at least one second potential connection which is designed to connect a second electrical potential which differs from the first potential and the ground conductor potential, at least one electrical switching device which is designed to establish an electrical connection, optionally in accordance with an electrical control signal, between the first potential connection and the ground conductor connection (connection state) or to interrupt same (interruption state), at least one control unit which is designed to automatically output control signals to the electrical switching device.
