Typical starting configuration
Behaviour & design
Boar investigate close to the ground. Gaps under gates and dips in the terrain can defeat an otherwise continuous fence. Inspect the bottom line after rain and rooting activity.
NARO describes a two-wire 20 / 40 cm layout in Japan. This is a sourced starting example, not a validated Malaysian standard. Young animals, uneven ground or mixed wildlife may require a revised barrier. Confirm voltage with the installer.
Wire layout & construction
| Wire | cm | Purpose |
|---|---|---|
| 1 | 20 | Live |
| 2 | 40 | Live |
Conductor
Compare smooth fence conductors by resistance per kilometre and breaking strength. Choose visible, suitable polywire for temporary divisions; verify its resistance before long runs. Never electrify barbed wire.
Posts & corners
Set post spacing for terrain, conductor sag and the manufacturer's tension limits. Brace corners and gates; use suitable insulators and lead-out cable. More posts may be needed on uneven ground.
Choose by fence load, not acreage
Energized wire length ≈ perimeter × live strands. PEMALL's existing estimator also considers vegetation. Its Joule band is a preliminary stored-energy estimate, not a guaranteed operating voltage. Conductor resistance, grounding, animal pressure and expansion must be checked against manufacturer load data.

AC / mains
For reliable power nearby. Use an approved mains-input energizer and weather-protected installation.
12 V battery
For compatible DC energizers. Plan charging, inspections and spare capacity before the battery runs low.
Solar + battery
For remote farms. Size from actual energizer consumption, shade and cloudy-day autonomy; protect equipment from flooding and theft.
Grounding & daily checks
Follow the energizer manual for earth rods, separation and earth-return wiring. Rain does not guarantee a good earth system. Test the far end and gates with a fence tester, clear tropical growth, and inspect after storms. Correct leakage and grounding before increasing energizer size.

Questions before you build
Is this also a monkey fence?
No. A low boar layout does not address climbing or overhead entry. Mixed wildlife needs a combined design.
Can I choose an energizer just from the animal?
No. Two farms with the same animal can have very different wire loads, vegetation, grounding and power needs. Use the planner, then verify the actual fence voltage during commissioning.
