be closed, this shall be eff ected by means of electrically non-conduc ve material or an isolated metal
barrier.
Barbed wire or razor wire shall not be electrifi ed by an energizer.
A non-electrifi ed fence incorpora ng barbed wire or razor wire may be used to support one or more
off -set electrifi ed wires of an electric animal fence. The suppor ng devices for the electrifi ed wires shall
be constructed so as to ensure that these wires are posi oned at a minimum distance of 150 mm from
the ver cal plane of the non-electrifi ed wires. The barbed wire and razor wire shall be earthed at regular
intervals.
Follow the energizer manufacturer's recommenda ons regarding earthing.
A distance of at least 10m shall be maintained between the energizer earth electrode and any
other earthing systm connected parts such as the power supply system protec ve earth or the
telecommunica on system earth.
Connec ng leads that are run inside buildings shall be eff ec vely insulated from the earthed structural
parts of the building. This may be achieved by using high voltage cable.
Connec ng leads that are run underground shall be run in conduit of insula ng material or else insulated
high voltage lead-out cable shall be used. Care must be taken to avoid damage to the connec ng leads
due to the eff ects of animal hooves or tractor wheels sinking into the ground.
Connec ng leads shall not be installed in the same conduit as the mains supply wiring, communica on
cables or data cables.
Connec ng leads and electric animal fence wires shall not cross above overhead power or
communica on 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 connec ng 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 following.
Minimum clearances from power lines for electric animal fences
Less than or equal to 1 000
Greater than 1 000 and less than or equal to 33 000
Greater than 33 000
If connec ng 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 projec on of the outermost conductors of the power
line on the ground surface, for a distance of:-
-
2 m for power lines opera ng at a nominal voltage not exceeding 1 000 V;
-
15 m for power lines opera ng 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 sa sfactory and safe performance.
In electric animal fences intended for deterring birds from roos ng on buildings, no electric fence wire
shall be connected to the energizer earth electrode. A warning sign shall be fi ed to every point where
persons may gain ready access to the conductors.
Where an electric animal fence crosses a public pathway, a non-electrifi ed gate shall be incorporated
in the electric animal fence at that point or a crossing by means of s les shall be provided. At any such
crossing, the adjacent electrifi ed wires shall carry warning signs.
Any part of an electric animal fence that is installed along a public road or pathway shall be iden fi ed by
electric fence warning signs (G6020) at regular intervals that are securely fastened to the fence posts or
fi rmly 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
inscrip on on the sign shall be black and shall be either:
-
the substance of "CAUTION: Electric Fence" or,
-
the symbol shown:
The inscrip on shall be indelible, inscribed on both sides of the warning sign
and have a height of at least 25mm.
