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.
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

≤1000 V
>1000 V to ≤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 1000 V.
•
15 m (50') for power lines operating at a nominal
voltage exceeding 1000 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:
or the substance of "CAUTION: Electric fence".
The inscription shall be indelible, inscribed on both sides
of the warning sign and have a height of at least 25 mm
(1").
Ensure that all mains-operated, ancillary equipment
connected to the electric animal fence circuit provides a
degree of isolation between the fence circuit and the
supply mains equivalent to that provided by the energizer.
Protection from the weather shall be provided for the
ancillary equipment unless this equipment is certified by
the manufacturer as being suitable for use outdoors, and
is of a type with a minimum degree of protection IPX4.
