Connecting leads shall not be installed in the
same conduit as the mains supply wiring,
communication cables or data cables.
Connecting leads and electric animal fence wires
shall not cross above overhead power or
communication lines.
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:
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 25 mm (1‛).
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.
