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 energizers or from
independent fence circuits of the same energizer.
For any two separate electric animal fences, each supplied from a separate energizer
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 energizer.
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.
