Power line voltage
> 1,000 ≤ 33,000 V
If connecting leads and electric 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 (7') for power lines operating at a nominal voltage not exceeding 1,000 V.
• 15 m (50') for power lines operating at a nominal voltage exceeding 1,000 V.
Energisers connected to electric fences shall not be installed in buildings with fire risk like
barns, storage sheds or stables. To prevent lightning damages you have to install lightning
protection (spark gap with earthing) in the leadout cable before you run it inside the building.
Electric fences intended for deterring birds, household pet containment or training animals
such as cows need only be supplied from low output energisers to obtain satisfactory and
safe performance.
In electric fences intended for deterring birds from roosting on buildings, no electric fence wire
shall be connected to the energiser earth stake. A warning sign shall be fitted to every point
where persons may gain ready access to the conductors.
Where an electric fence crosses a public pathway, a non­electrified gate shall be incorporated
in the electric 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 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 x 200 mm (4 x 8").
• 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
like the illustration to the right or the substance of
"CAUTION: Electric animal fence".
• The inscription shall be indelible, inscribed on both sides of the warning sign
and have a height of at least 25 mm (1").
Ensure that all mains­operated, ancillary equipment connected to the electric fence circuit
provides a degree of isolation between the fence circuit and the supply mains equivalent
to that provided by the energiser.
