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

an earth stake. A warning sign shall be ﬁ ed to every point where persons may gain ready access to the conductors.

• Fence wiring should be installed well away from any telephone or telegraph line or radio aerial.

• 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.

This energizer complies with interna onal safety regula ons and is manufactured to interna onal standards.
