Claim 13:
14. A gas insulated switchgear (GIS) device comprising:
a frame defining a sealed interior compartment;
an electrical breaker component carried within the sealed interior compartment, the sealed interior compartment comprising an upper compartment above the electrical breaker component, and a lower compartment below the electrical breaker component;
a first optical sensor carried within the sealed interior compartment;
a grounding device coupled to the electrical breaker component and being within the sealed interior compartment, the grounding device comprising
an axle extending between the sealed interior compartment and an exterior of the frame,
a magnetic actuation device coupled to a distal end of the axle,
a linkage coupled to the axle, and
a grounding switch coupled to the linkage and switching between a first open state and a second closed state, the grounding switch comprising at least one switch arm coupled to the linkage and having a first end, and a second end opposite the first end, the first end being coupled to the frame;

three incoming cable connectors carried in the upper compartment, and three outgoing cable connectors carried in the lower compartment; and
a controller coupled to the electrical breaker component, the first optical sensor, and the grounding device and configured to
cause the grounding switch to switch to the second closed state based upon the first optical sensor, and
cause the electrical breaker component to switch to an open state based upon the first optical sensor.
