reference ground is typically a metal stake in the ground to which the ground
conductors from one or more buildings are attached.

, a
star ground
is often used to obtain the same earth reference
ground. Each earth reference ground, such as the system base ground, is returned

problems associated with an unpredictable or uncharacterized grounding system will
occur.
