Switchgear ground and test device having ground shoe assembly with conductive clamp assembly and associated methods

A ground and test (G&T) device, comprising:

• a test device housing configured to be installed within a compartment of a switchgear frame into a testing position;
• a ground shoe assembly carried by the test device housing configured to engage a grounding circuit having a grounding bar carried by the switchgear frame, said ground shoe assembly comprising a conductive clamp assembly configured to slide on the grounding bar as the test device housing is moved into the testing position, wherein the conductive clamp assembly is configured to clamp onto the grounding bar in secure electrical contact when the test device housing is in the testing position;
• a plurality of upper terminals and plurality of lower terminals carried by the test device housing, said upper and lower terminals configured to connect to load and line conductors of the switchgear frame when in the testing position;
• a lower ground bus bar carried by the test device housing, said ground shoe assembly connected to the lower ground bus bar;
• and
• a plurality of grounding bars that selectively connect either the upper terminals to the lower ground bus bar or connect the lower terminals to the lower ground bus bar.
