For any two separate electric fences, each supplied from a separate energiser independently
timed, the distance between the wires of the two electric fences shall be at least 2 m (6'6"). If
this gap is to be closed, this shall be effected by means of electrically non­conductive material
or an isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an energiser.
A non­electrified fence incorporating barbed wire or razor wire may be used to support one
or more offset electrified wires of an electric fence. The supporting devices for the electrified
wires shall be constructed so as to ensure that these wires are positioned at a minimum dis­
tance of 150 mm (6") from the vertical plane of the non­electrified wires. The barbed wire and
razor wire shall be earthed at regular intervals. For safety reasons we recommend for offset
fences only to use energisers with a maximum of 5 joules output energy.
Follow our recommendations regarding earthing. See "Installing and testing an earth system"
on page 42.
A distance of at least 10 m (33') shall be maintained between the energiser earth stake 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, com­
munication cables or data cables.
Connecting leads and electric fence wires shall not cross above overhead power or communi­
cation 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 fence wires are installed near an overhead power line, the
clearances shall not be less than those shown in the table below.
Minimum clearances from power lines for electric fences

If connecting leads and electric fence wires are installed near an overhead power line, their
