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 unit is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction
concerning use of the unit by a person responsible for
their safety.
Children should be supervised to ensure that they do
not play with the unit.
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 units or from independent fence circuits of
the same unit.
For any two separate electric animal fences, each
supplied from a separate unit independently timed, the
distance between the wires of the two electric animal
fences shall be at least 8’ (2.5 m). 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 a
unit.
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 6” (150 mm)
from the vertical plane of the non-electrified wires. The
barbed wire and razor wire shall be grounded at
regular intervals.

information about grounding.
A distance of at least 33’ (10 m) shall be maintained
between the unit’s ground electrode and any other
grounding system connected parts such as the
grounding system for the power supply or the
telecommunication system.
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.
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.

animal fences

If connecting leads and electric animal fence wires are
installed near an overhead power line, their height
above the ground shall not exceed 10’ (3 m). 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:
•
6’6” (2 m) for power lines operating at a
nominal voltage not exceeding 1000 V.
•
50’ (15 m) 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 units 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 unit’s ground electrode.
Ensure that all line-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 unit.
