THE EARTH GROUNDING SYSTEM
a
Theory. An earth grounding system helps keep the electrical potential on metal surfaces at the same level
as the surrounding earth. Earth grounding also provides a discharge path for externally generated electrical surges,
including lightning. An earth ground is made by electrically connecting a generator, shelter or structure to a buried metal
conductor which is in con- tact with moist subsoil or reaches into the underground water table The type of ground
conductor and method of installation you use depends on the climate and soil conditions of the site
b Ground rods and plates. A ground rod is generally the most effective conductor. You may get a good ground by
connecting to a buried metal object already at the site, such as a metal pipe or a steel building frame. In the desert or
other places where
