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.

fences

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 animal 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.
