10.3 Particular requirements for electric animal fences in
Australia
15. A distance of at least 10 m shall be maintained between the energizer earth
electrode and any other earthing system such as the power supply system
protective earth or the telecommunication system earth.
16. Electric 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.
17. In electric fences intended for deterring birds from roosting on buildings, no
electric fence wire shall be connected to the energizer earth electrode. A warning
plate, as described above, shall be fitted to every point where persons may gain
ready access to the conductors.
18. A non-electrified fence incorporating barbed wire or razor wire may be used to
support one or more off-set 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 from the
vertical plane of the non-electrified wires. The barbed wire and razor wire shall
be earthed at regular intervals.
19. Where an electric animal fence crosses a public pathway, a non-electrified gate
shall be incorporated in the electric fence at the point or a crossing by means of
stiles shall be provided. At any such crossing, the adjacent electrified wires shall
carry warning plates as described above.
10.4 Installation of electric security fences
10.4.1 General
An electric security fence should be installed so that, under normal conditions of
operation, persons are protected against inadvertent contact with pulsed conductors.
Note 1
: This requirement is primarily intended to establish that a desirable level of
safety is present or is being maintained in the physical barrier.
Note 2
: When selecting the type of physical barrier, the likely presence of young
children should be a factor in considering the size of openings.
10.4.2 Location of electric security fence
The electric fence should be separated from the public access area by means of a
physical barrier.
Where an electric fence is installed in an elevated position, such as on the inner side
of a window or skylight, the physical barrier may be less than 1.5 m high where it
covers the whole of the electric fence. If the bottom of the window or skylight is within
a distance of 1.5 m from the floor or access level then the physical barrier need only
extend up to a height of 1.5 m above the floor or access level.
