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
Table 1.
Power line voltage
> 1 000 and ≤ 33 000
Table 1 – Minimum clearances from power lines for electric animal fences
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 to 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 the energizer earth electrode. 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 at frequent intervals by warning signs securely
fastened to the fence posts or firmly clamped to the fence wires.
The size of the warning sign shall be at least 100 mm × 200 mm.
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
