Select a suitable site for the ground
system. Sites need to be:
At least 33' (10 m) from other
ground systems (e.g. telephone,
110 V power or the ground
system from another energizer).
Away from stock or other traffic
that could interfere with the
installation.
At a site that can be easily
observed for maintenance.
Ideally at a site that has damp soil
(e.g. a shaded or swampy
location). Note that the ground
does not need to be directly
adjacent to the energizer
installation.
Drive ground rods into the soil. Use
high-voltage, insulated cable and
ground clamps to continuously connect
the ground rods and the energizer's
Fence ground terminal. Make sure the
insulation is stripped back to ensure
good contact between the wire and the
ground rod. The table below specifies
the minimum number of ground rods
recommended for a grounding system:

For an all live fence only, test the
ground system using the following
procedure:
1
Turn off the energizer.
2
At least 330' (100 m) away from
the energizer, short-circuit the
fence by laying several steel rods

or lengths of pipe against the
fence. For best results, the fence
voltage should be lowered to 2 kV
or less. In dry or sandy conditions,
it may be necessary to drive the
rods up to 12" (300 mm) into the
ground.
Note: It is not acceptable to short-
circuit a ground wire return
system to the ground wire of the
fence.
3
Turn the energizer back on.
4
Using a digital voltmeter, ensure
that the fence voltage is below
2 kV.
5
Check your ground system. Insert
the voltmeter's ground probe into
the ground at the full extent of the
lead, and hold the other terminal
against the last ground rod. The
tester should not read more than
0.3 kV. Anything higher than this
indicates that better grounding is
required. Either add more ground
rods or find a better ground area
to drive in the ground rods.
Note: When grounding energizers
located in dairies, ground at least
65' (20 m) away from the dairy
using double-insulated wire to
avoid touching the dairy building
or equipment.
