Gates in electric security fences shall be capable of being opened without the
person receiving an electric shock.
The energizer earth electrode shall penetrate the ground to a depth of at least
1m. The distance between any electric security fence earth electrode and other
earth systems shall not be less than 2m.
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.
Connecting leads and electric fence wires shall not cross above overhead power
or communication lines.
Mains supply wiring shall not be installed in the same conduit as signalling leads
associated with the electric security fence installation.
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 fence wires are installed near an overhead power
line, the clearances shall not be less than those shown in Table 1.
