General requirements for electric fences
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 the entanglement of animals or
persons shall be avoided.
An electric fence shall not be supplied from two different energizers or from independent
fence circuits of the same energizer.
For any two different electric fences, each supplied from a different energizer with
independent timing, the distance between the wires of the two electric fences shall be at
least 2.5m. If this gap is to be closed, this shall be affected by means of electrically non-
conductive material or an isolated metal barrier.
Barbed wire or razor wire shall not be electrified by an energizer.
Electric fences and their ancillary equipment shall be installed, operated and maintained in a
manner that minimizes danger to persons, and reduces the risk of persons receiving an
electric shock unless they attempt to penetrate the physical barrier, or are in a secure area
without authority. Exposed conductive parts of the physical barrier shall be effectively
earthed.
A spacing of 2.5m shall be maintained between non insulated electric fence conductors or
non insulated connecting leads supplied from different energizers. This spacing may be less
where conductors or connecting leads are covered by insulating sleeving, or consist of
insulated cables, rated to at least 10kV.
This requirement need not apply where the separately energized conductors are separated by
a physical barrier, which does not have any openings greater than 50mm.
A vertical separation of not less than 2m shall be maintained between pulsed conductors fed
from different energizers.
Ensure that all ancillary equipment connected to the electric 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 to 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.
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 a conduit of insulating material or
else insulated high voltage cable shall be used. Care shall be taken to avoid damage to the
connecting leads due to external factors.
Connecting leads shall not be installed in the same conduit as the mains supply wiring,
communication cables or data cables.
