An electric animal fence shall not be supplied from
two separate energizers or from independent fence
circuits of the same energizer.
For any two separate electric animal fences, each
supplied from a separate energizer independently
timed, the distance between the wires of the two
electric animal fences shall be at least 2 m (6'6"). If
this gap is to be closed, this shall be effected by
means of electrically non-conductive material or an
isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an
energizer.
A non-electrified fence incorporating barbed wire or
razor wire may be used to support one or more offset
electrified wires of an electric animal fence. The
supporting devices for the electrified wires shall be
constructed so as to ensure that these wires are
positioned at a minimum distance of 150 mm (6")
from the vertical plane of the non-electrified wires.
The barbed wire and razor wire shall be earthed at
regular intervals.
Follow our recommendations regarding earthing. See
Installing and testing an earth system on page 8.
A distance of at least 10 m (33') shall be maintained
between the energizer earth electrode and any other
earthing system connected parts such as the power
supply system protective earth or the
telecommunication system earth.
Connecting leads that are run inside buildings shall be
effectively insulated from the earthed structural parts
of the building. This may be achieved by using
insulated high voltage cable.
Connecting leads that are run underground shall be
run in conduit of insulating material or else insulated
high voltage cable shall be used. Care must be taken
to avoid damage to the connecting leads due to the
effects of animal hooves or vehicle wheels sinking into
the ground.
Connecting leads shall not be installed in the same
conduit as the mains supply wiring, communication
cables or data cables.
Connecting leads and electric animal fence wires shall
not cross above overhead power or communication
lines.
Crossings with overhead power lines shall be avoided
wherever possible. If such a crossing cannot be
avoided it shall be made underneath the power line
and as nearly as possible at right angles to it.

If connecting leads and electric animal fence wires are
installed near an overhead power line, the clearances
shall not be less than those shown in the table below.
Minimum clearances from power lines for electric
animal fences
Power line voltage
≤1,000 V
>1,000 ≤33,000 V
>33,000 V
If connecting leads and electric animal fence wires are
installed near an overhead power line, their height
above the ground shall not exceed 3 m (10'). This
height applies to either side of the orthogonal
projection of the outermost conductors of the power
line on the ground surface, for a distance of:
2 m (6'6") for power lines operating at a nominal
•
voltage not exceeding 1,000 V.
15 m (50') for power lines operating at a
•
nominal voltage exceeding 1,000 V.
Electric animal fences intended for deterring birds,
household pet containment or training animals such
as cows need only be supplied from low output
energizers to obtain satisfactory and safe
performance.
In electric animal fences intended for deterring birds
from roosting on buildings, no electric fence wire shall
be connected to the energizer earth electrode. A
warning sign shall be fitted to every point where
persons may gain ready access to the conductors.
Where an electric animal fence crosses a public
pathway, a non-electrified gate shall be incorporated
in the electric animal fence at that point or a crossing
by means of stiles shall be provided. At any such
crossing, the adjacent electrified wires shall carry
warning signs.
Any part of an electric animal fence that is installed
along a public road or pathway shall be identified at
frequent intervals by warning signs securely fastened
to the fence posts or firmly clamped to the fence
wires.
The size of the warning sign shall be at least
•
100x200 mm (4x8").
The background colour of both sides of the
•
warning sign shall be yellow. The inscription on
the sign shall be black and shall be either:
Clearance
3 m (10')
4 m (13')
8 m (27')
