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
energisers 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 energiser 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
10
the supply mains equivalent to that provided by the
energiser.
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.
Requirements for electric security fences
Electric security fences and their ancillary equipment
shall be installed, operated and maintained in a
manner that minimises danger to persons, and
reduces the risk of persons receiving an electric shock
unless they attempt to penetrate the physical barrier,
or are in the secure area without authority.
Electric security fence constructions that are likely to
lead to the entanglement of persons shall be avoided.
Gates in electric security fences shall be capable of
being opened without the person receiving an electric
shock.
An electric security fence shall not be supplied from
two separate energisers or from independent fence
circuits of the same energiser.
For any two separate electric security fences, each
supplied from a separate energiser independently
timed, the distance between the wires of the two
electric security fences shall be at least 2.5 m (9'). 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
energiser.
Follow our recommendations regarding earthing. See
Installing and testing an earth system on page 7.
The distance between any electric security fence earth
electrode and other earth systems shall not be less
than 2 m (6'6"), except when associated with a
graded earth mat.
Note: Where possible this distance should be at least
10 m (33').
Exposed conductive parts of the physical barrier shall
be effectively earthed.
Where an electric security fence passes below bare
power line conductors, the highest metallic element
shall be effectively earthed for a distance of not less
than 5 m (17') on either side of the crossing point.
