Safety Requirements and Regulations
Electric fences shall be installed and operated so that they cause no electrical hazard to persons, animals
or their surroundings.
·
Electric fence constructions, which are likely to lead to entanglement of animals or persons, shall
be avoided.
·
An electric fence shall not be supplied from more than one energiser or from independent fence
circuits of the same energiser.
·
The gap between two separate electric fences with different energisers shall be at least 2m.
·
If this gap is to be closed, this should be affected by means of an electrically non conductive
material.
·
Barbed or razor wire shall not be electrified by an energiser.
·
Any part of an electric fence which is installed along a public path or highway shall be identified
by warning signs (p/no 33020) securely fastened to the fence posts or firmly clamped to the fence
wires at recommended intervals of approximately 10 metres to 50 metres, but not exceeding 90
metres. Warning signs should be at least 100mm x 200mm with a yellow background. The
inscription shall be black and read:
TAKE CARE - ELECTRIC FENCE
, it should be indelible
and inscribed on both sides, lettering height of at least 25mm.
·
Except for low output battery operated energisers, the energiser earth electrode shall penetrate the
ground to a depth of at least 1m.
·
Connecting leads that are run inside buildings shall be effectively insulated from the earth
structural parts of the building. This may be achieved by using double insulated high voltage cable
(p/no 31640). Connecting leads that are run underground shall be run in a conduit of insulating
material.
·
Care shall be taken to avoid damage to the connecting leads due to the effects of animal hooves or
tractor 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 fence wires shall not cross above overhead power or communication
lines.
·
Crossings with overhead cables 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 fences are installed near an overhead power line the clearances
shall be:
1.
Power Line Voltage:
Under 1000 volts -
Clearance:
3 Metres
2.
Power Line Voltage:
1000 - 33,000 volts -
Clearance:
4 Metres
3.
Power Line Voltage:
Over 33,000 volts -
Clearance:
8 Metres
·
If connecting leads and electric fence wires are installed near an overhead power line, their height
above ground shall not exceed 2m. This height applies either side of the orthogonal projection of
the outermost conductors of the power line on the ground surface, for a distance of - 2m for power
lines not exceeding 1000V - 15m for power lines exceeding 1000V.
·
A distance of 10m shall be maintained between the energiser and any other earth system such as
the household supply system protective earth or the telecom system earth.
·
A warning sign as described earlier, 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 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 as described earlier.
