1. A system, comprising:
an electric consumer; and
an electrical device including an operating device and wires adapted to supply the consumer, a first one of the wires adapted to conduct a first phase of a three-phase voltage during a normal operation, a second one of the wires adapted to conduct a second phase of the three-phase voltage, a third one of the wires adapted to conduct a third phase of the three-phase voltage, the wires adapted to supply the consumer with the three-phase voltage during the normal operation;
wherein the operating device is adapted to connect the first wire to the first phase of the three-phase voltage during the normal operation, and to separate the first wire from the first phase of the three-phase voltage and to connect the first wire to the second phase of the three-phase voltage in a safety case.
