• 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.
• 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.
• Ensure that all mains operated, ancillary equipment connected to the electric animal
fence circuit provides a degree of isola on between the fence circuit and the supply
mains equivalent to that provided by the energizer.
• Protec on from the weather shall be provided for the ancillary equipment unless
this equipment is cer fi ed by the manufacturer as being suitable for use outdoors,
and is of a type with a minimum degree of protec on IPX4.
