Minimum clearances from power lines for electric animal fences
Power line voltage
≤1000 V
>1000 V to ≤33,000 V
>33,000 V
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 (10'). 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 (6'6") for power lines operating at a nominal voltage not exceeding 1000 V.
15 m (50') for power lines operating at a nominal voltage exceeding 1000 V.
To prevent lightning damages you have to install lightning protection (spark gap
with earthing) in the leadout cable before you run it inside a building which is not
liable to catch fire.
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
