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
Distance
1000 V
10’ (3 m)
>1000 to 33,000 V
13’ (4 m)
>33,000 V
14’ (8 m)
If connecting leads and electric animal
fence wires are installed near an
overhead power line, their height
above the ground shall not exceed 10’
(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:
 6’6” (2 m) for power lines
operating at a nominal voltage not
exceeding 1000 V.
 50’ (15 m) 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 ground
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 4x8” (100x200 mm).
 The background color of both
sides of the warning sign shall be
yellow. The inscription on the sign
shall be black and shall be either:
or the substance of "CAUTION:
Electric Fence".
 The inscription shall be indelible,
inscribed on both sides of the
warning sign and have a height of
at least 1” (25 mm).
Ensure that all mains-operated,
ancillary equipment connected to the
electric animal fence circuit provides a
degree of isolation between the fence
circuit and the supply mains equivalent
to that provided by the energizer.
Protection from the weather shall be
provided for the ancillary equipment
unless this equipment is certified by
the manufacturer as being suitable for
use outdoors, and is of a type with a
minimum degree of protection IPX4.
