Grounding Considerations

Express5800/320Ma: Site Planning Guide
reference ground is typically a metal stake in the ground to which the ground
conductors from one or more buildings are attached.
As shown in
Figure B-1
, 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
separately to a common point where a zero-volt (0V) earth ground exists. The star
ground ensures that all equipment is at the same potential and that no noise or safety
problems associated with an unpredictable or uncharacterized grounding system will
occur.
