Building a permanent electric fence
For information about building a permanent electric fence,

Temporary electric fencing
Patriot offers a range of products that allow the farmer to
construct a temporary electric fence. A temporary fence that
can be quickly erected and easily moved allows the farmer to:
•
Make smaller paddocks (fields)
•
Keep herds of animals separated
•
Ration feed
Note:
Use more wires for smaller animals and wild animals.
Politape should be used when greater visibility is required (e.g.
horses).
An example of a temporary fence is shown below.
Safety considerations
Definition of special terms
Electric fence controller
– An appliance that is intended to
periodically deliver voltage impulses to a fence connected to it.
Fence
– A barrier for animals or for the purpose of security,
comprising one or more conductors such as metal wires, rods
or rails.
Electric fence
– A barrier which includes one or more electric
conductors, insulated from ground, to which electric pulses
are applied by an electric fence controller.
Fence circuit
– All conductive parts or components within an
electric fence controller that are connected or are intended to
be connected, galvanically, to the output terminals.
Ground electrode
– Metal structure that is driven into the
ground near an electric fence controller and connected
electrically to the Fence ground terminal of the electric fence
controller, and that is independent of other grounding
arrangements.
Connecting lead
– An electric conductor, used to connect the
electric fence controller to the electric fence or the ground
electrode.
Electric animal fence
– An electric fence used to contain
animals within or exclude animals from a particular area.
Electric security fence
– A fence used for security purposes
which comprises an electric fence and a physical barrier
electrically isolated from the electric fence.
Physical barrier
– A barrier not less than 1.5 m (5’) high
intended to prevent inadvertent contact with the pulsed
conductors of the electric fence. Physical barriers are typically
constructed from vertical sheeting, rigid vertical bars, rigid
mesh, rods or chainwire mesh.
Public access area
– Any area where persons are protected
from inadvertent contact with pulsed conductors by a physical
barrier.
Pulsed conductors
– Conductors which are subjected to high
voltage pulses by the electric fence controller.
Secure area
– The side of an electric security fence where a
person may come into contact with the electric fence, without
the protection of a physical barrier.
Requirements for electric animal fences
Electric animal fences and their ancillary equipment shall be
installed, operated and maintained in a manner that minimises
danger to persons, animals or their surroundings.
This electric fence controller is not intended for use by young
children or infirm persons unless they are adequately
supervised by a responsible person to ensure that they can use
the electric fence controller safely.
Young children should be supervised to ensure that they do
not play with the electric fence controller.
Electric animal fence constructions that are likely to lead to the
entanglement of animals or persons shall be avoided.
An electric animal fence shall not be supplied from two
separate electric fence controllers or from independent fence
circuits of the same electric fence controller.
For any two separate electric animal fences, each supplied
from a separate electric fence controller 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 electric
fence controller.
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 grounded at
regular intervals.
Follow our recommendations regarding grounding.
A distance of at least 10 m (33’) shall be maintained between
the electric fence controller ground electrode and any other
grounding system connected parts such as the power supply
system protective ground or the telecommunication system
ground.
Connecting leads that are run inside buildings shall be
effectively insulated from the grounded 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.
