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 the table below.
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.
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 100x200 mm (4x8").
•
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:
Clearance
3 m (10')
4 m (13')
8 m (27')
