Building an electric fence
For detailed information on building an electric fence and an earth system, visit the
website (see energizer packaging for details).
Installing and testing an earth system
Select a suitable site for the earth system. Sites need to be at least 10 m (33') from
other earth systems (e.g. telephone, mains power or the earth system of another
energizer).
Drive the required number of earth rods into the ground. Use high-voltage, insulated
cable and earth clamps to continuously connect the earth rods and the energizer's
Fence earth terminal. Make sure the insulation is stripped back to ensure good contact
between the wire and the earth rod. The table below specifies the minimum number of
2 m (6'6") earth rods recommended for an earthing system:
