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 lead-out cable shall be used. Care must be taken to avoid damage to the connecting leads due
to the effects of animal hooves or tractor 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.
Minimum clearances from power lines for electric animal fences
Power line Voltage V
Clearance m
Less than or equal to 1 000
3
Greater than 1 000 and less than or equal to 33 000
4
Greater than 33 000

•
If connecting leads and electric animal fence wires are installed near an overhead power line, their height
above the ground shall not exceed 3 m
This height applies either side of the orthogonal projection of the outermost conductors of the power line
on the ground surface, for a distance of:
-
2 m for power lines operating at a nominal voltage not exceeding 1 000 V;
-
15 m for power lines operating at a nominal voltage exceeding 1 000 V.
•
Electric animal 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.
•
In electric animal fences intended for deterring birds from roosting on buildings, no electric fence wire shall
be connected to an earth stake. A warning sign shall be fitted to every point where persons may gain ready
access to the conductors.
•
Where an electric animal fence crosses a public pathway, a non-electrified gate shall be incorporated in the
electric animal fence at that point or a crossing by means of stiles shall be provided. At any such crossing,
the adjacent electrified wires shall carry warning signs.
• Any
part of an electric animal fence that is installed along a public road or pathway shall be identified by
electric fence warning signs (G6020) at regular intervals that are securely fastened to the fence posts or
firmly clamped to the fence wires.
•
The size of the warning sign shall be at least 100mm x 200mm.
•
The background colour of both sides of the warning sign shall be yellow. The
inscription on the sign shall be black and shall be either:
-
the substance of “CAUTION: Electric Fence” or,
-
the symbol shown:
