A system having electric consumers includes an electrical device including an operating device and wires supplying the consumer. A first wire is provided for conducting the first phase of a three-phase voltage during a normal operation, a second wire conducts a second phase of the three-phase voltage, and a third wire conducts a third phase of the three-phase voltage. The consumer is able to be supplied with the three-phase voltage from the wires during a normal operation. The operating device is configured so that: in a normal operation, the first wire is connected to the first phase of the three-phase voltage; and in a safety case, the first wire is separated from the first phase of the three-phase voltage and will be or is connected to the second phase of the three-phase voltage.
