3.8 Fence earth system — One or more electrodes together with connecting leads and accessories which are used to maintain part of the fence in effective electrical contact with earth.
3.9 Insulator — Device intended to permanently prevent the passage of current from wires carrying pulses.
3.10 Type D energizer — Battery-operated energizer suitable for connection to the mains consisting of an impulse generating circuit intended to be powered by a battery, the impulse generating circuit being connected to the battery when the energizer is in operation and the energizer or the battery being connected to a separate battery charger for recharging the battery.
4 COMPONENTS
4.1 Energizers and ancillary equipment
All electric fence energizers shall comply with AS/NZS 3350.2.76.
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.
4.2 Insulation
Uninsulated fence wires and connecting leads shall be supported on insulators of durable non-conducting material. This requirement does not apply to connecting leads consisting of cable with high voltage insulation.
4.3 Barbed wire and razor wire
Strands of barbed or razor wire in an electric fence shall not be electrified.
A plain wire in an existing fence containing barbed wire or razor wire may be electrified provided the electrified wire is offset horizontally from the plane of the fence wires by not less than 150 mm.
4.4 Battery chargers
A battery-powered energizer shall not be supplied from:
(a) A storage battery that is simultaneously charged on an a.c. supply mains powered charger; or
(b) A d.c. power supply that is itself supplied at greater than 50 V a.c. or greater than 120 V d.c.
This applies unless the energizer is classified by the manufacturer as being type D.
5 INSTALLATION
5.1 General
Electric fence equipment shall be installed and operated in a manner that:
(a) Minimizes hazards to persons, animals and property;
(b) Minimizes the possibility of a person or animal becoming entangled or entrapped and receiving multiple shocks; and
(c) Minimizes the possibility of a person or animal being injured by a secondary cause (e.g. drowning or falling from an elevated position) after receiving one or more shocks.AS NZS 3014 pdf download.
