Proper Grounding Practices

Grounding is one of the most important parts of equipment installation. Proper grounding practices
ensure that the buildings and the installed equipment within them have low-impedance connections and
low-voltage differentials between chassis. When you properly ground systems during installation, you
reduce or prevent shock hazards, equipment damage due to transients, and data corruption.
lists some general grounding practice guidelines.

Environment
Commercial building is
subjected to direct lightning
strikes.
For example, some places in the
United States, such as Florida,
are subject to more lightning
strikes than other areas.
Commercial building is located
in an area where lightning
storms frequently occur but is
not subject to direct lightning
strikes.
Commercial building contains a
mix of information technology
equipment and industrial
equipment, such as welding.
