Location of the earthing system
The following examples are to help you locate a suitable position for your earthing system given a
variety of conditions:
1. All live earthing system: Recommended where the soil is highly conductive, i.e. most moist soils.
2. Earth-wire return earthing system: Where soils are not conductive e.g. dry, sandy, pumice soils
as well as frozen soils or snow conditions, an earth-return wire should be used in conjunction
with the earthing system – as per diagram
3. Bentonite salt earthing system: A known alternative for extremely dry soil conditions. A mixture
of bentonite and coarse salt (10 lbs bentonite : 5 lbs coarse salt, mixed into a slurry) is placed in
and around each earth stake. The salt attracts moisture making it highly conductive, while the
bentonite retains moisture over prolonged periods.
Note: For this particular application stainless steel earth stakes are required to prevent salt
corrosion and should be spaced 10 m apart.
