120, for this subject matter where the system includes signal means, an indicator, or an alarm.
121, and indented subclass, for this subject matter where there are a plurality of load devices in the system.
123, for this subject matter where the system includes a plurality of shunts and/or cutouts.
124, for this subject matter where the electrically operated switch is controlled by an auxiliary electrode in the load device.
125, and indented subclass, for this subject matter where the switch closes a shunt circuit about the load device.
