words "Caution Electric fence" or have a symbol to represent a hand and shock in
Black. The inscription shall be indelible, inscribed on both sides of the warning sign
Electric fences must not be supplied from two separate energizers or from independent
fence circuits of the same energizer.
•
Avoid contacting electric fence wires especially with the head, neck or torso.
Do not climb over, through or under an electric fence. Use a gate or a
specially designed crossing point.
•
For any two separate electric animal fences, each supplied from a separate
energizer independently timed, the distance between the wires of the two
electric animal fences shall be at least 2.5 m. If this gap is to be closed, this
shall be affected by means of electrically nonconductive material or an
isolated metal barrier.
•
Barbed wire or razor wire MUST NOT be electrified by an energizer.
•
A distance of at least 10 m shall be maintained between the energizer earth
electrode and any other earthing system connected parts such as the power
supply system protective earth or the telecommunication system earth.
•
Connecting leads that are run inside buildings shall be effectively insulated
from the earthed 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 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.
•
If an electric fence has to be installed under or near overhead power lines it
should NOT cross above it or run in parallel to it for any big distance.
Electric fencing should done at right angles to the power lines, the distance
from the ground to the top of the fence should not exceed 2 meters, and the
fence or any part of it should be no closer to the overhead wires than those
values shown below;
