A distance of at least 33' (10 m) shall be
maintained between the unit's ground electrode
and any other grounding system connected
parts such as the grounding system for the
power supply or the telecommunication system.
Connecting leads that are run inside buildings
shall be effectively insulated from the grounded
structural parts of the building. This may be
achieved by using insulated high voltage cable.
Connecting leads that are run underground
shall be run in conduit of insulating material or
else insulated high voltage cable shall be used.
Care must be taken to avoid damage to the
connecting leads due to the effects of animal
hooves or vehicle wheels sinking into the
ground.
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
10' (3 m). This height applies to either side of
6
Clearance
10 ' (3 m)
13' (4 m)
27' (8 m)
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 units 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 unit's
ground electrode.
Ensure that all line-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 unit.
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.
Service of double insulated
appliances
In a double insulated electric fence
charger/energizer, two systems of insulation are
provided instead of grounding. This unit
contains no serviceable parts.
