Quick Answers (Before You Start)

Height & wires
Use 4–6 hot wires. Make the fence about 42–46 in tall.
Target voltage
Aim for 4,000–5,000 V on the fence line for goats. If you must stop predators, use ≥5,000 V.
Grounding
Use multiple ground rods. Keep each rod at least 10 ft apart. A simple rule: ~3 ft of ground rod per joule of energizer output.

Plan Your Fence (Layout & Type)

Before you build, choose the fence style.

Pick one: Permanent high-tensile, Portable netting, or Offset wires on your old fence.

Goats are curious and nimble—keep wires close to the ground and the top high enough to stop jumping. For goats, low wires ~6–8 in apart near the ground and overall height about 42–46 in work well.

Permanent High-Tensile (4–6 wires, ~42–46 in) – strong corners, braces, tight wire.

Best for long borders and big, fixed paddocks.

Use 4–6 smooth, high-tensile wires. Build strong corners and braces, then tension the wires tight. Aim for a top wire around 42–46 in. Check and keep it hot.

When to choose: Long perimeter lines, year-round paddocks, windy or rough ground.

Portable Netting (≈42 in net) – fast to move; good for rotational grazing.

Great for small paddocks and moving animals often.

A 42-in goat/sheep net goes up fast and shifts easily for rotational grazing. It bends around dips and corners, so you can reshape paddocks in minutes.

When to choose: Daily/weekly moves, trial layouts, seasonal grazing blocks.

Retrofit Existing Fence (offset “hot” wires) – add 1–2 hot offsets to woven/mesh to stop climbing.

Already have woven/mesh? Add 1–2 electric “offset” wires on the inside: one near the top (stops climbing/jumping) and one low (stops pushing/creeping under). Offsets also keep pressure off an older fence and extend its life.

When to choose: You want low cost, quick upgrades, and better respect for an old fence.

Quick picks

Small paddocks / move often: Portable netting.
Long perimeter / fixed layout: Permanent high-tensile.
Have a fence already: Add 1–2 offset hot wires.

Parts You Need

1) Energizer (AC / DC / solar)

Pick the power size by your fence length and how much grass touches the wire. Your goal is to keep the fence reading about 4–5 kV (4,000–5,000 volts).

2) Grounding system

Use at least 3 ground rods, each 6–8 ft long. Put the rods 10 ft apart. For big (high-joule) energizers or dry soil, add more/longer rods so the fence shocks well.

3) Posts & Insulators

Use strong corner posts at turns; use lighter line posts between corners. Choose insulators that match your post (wood/T-post/fiberglass) and your wire (tape/rope/wire) so the hot wire does not touch the post.

4) Wire (aluminum / steel / polywire)

Aluminum carries power best (about 4× better than steel). Steel is tough and cost-effective for long lines. Polywire/tape/rope is easy to see (great for horses) but has more resistance, so use good-quality products.

5) Gates & Underground cable

Carry the “hot” power under the gate with insulated 12½-gauge cable. Bury it and protect it so wheels and hooves don’t damage it.

6) Tester / Fault finder (check often)

Use a fence tester to read the voltage (aim for your 4–5 kV target). A fault finder shows the direction of shorts so you can fix problems fast. Test from the energizer and at key spots like gates.

Design Specs (Height, Wire Spacing & Voltage)

Height & Wires

Use 4–5 wires for most herds. For jumpy goats, pick 5–6 wires. Aim for a fence about 42 inches tall (you can go up to 46 inches). Example 5-wire spacing from the ground: 6″, 12″, 20″, 30″, 40″. For a taller 6-wire setup: 6″, 12″, 18″, 24″, 32″, 42″.

Voltage (keep the fence “hot”)

Keep 4,000–5,000 volts on the live wires for goats. If you have predators (coyotes, wolves, bears), keep it at ≥5,000 volts. Use a fence tester to check regularly.

Safety Note

Do not electrify barbed wire. Use smooth wire or tape instead to avoid tangles and injury.

Install It: A Clear Step-by-Step

1) Map & clear the line

Walk the fence path. Cut tall grass and brush so they won’t touch the wire and drain power.

2) Set corners & braces (strong first)

Put in corner/end posts and brace them well (H-brace is common). Strong corners keep wires tight.

3) Drive line posts (even spacing)

Add line posts in straight rows with even gaps. Don’t space so far that wires sag.

4) Mount insulators (match post & wire)

Clip on the right insulators so the hot wire doesn’t touch the posts.

5) String wires (start low; tighter near ground)

Run the lowest wire close to the ground so animals can’t crawl under; keep gaps small enough so heads can’t fit through.

6) Cross-connect long runs

Join live wires together at both ends—and at regular intervals on long fences—to keep voltage even. (Use proper clamps.)

7) Add gate & underground cable

Carry power across the opening with double-insulated underground cable buried under the gate (not over it).

8) Install ground rods (do more than one)

Use several ground rods with plenty of total length; space rods at least 10 ft (3 m) apart in moist soil for best results.

9) Connect the energizer

Red (fence/hot) goes to the live wires; green/black (ground) goes to the ground rods. Keep all live parts insulated.

10) Test voltage

Use a fence tester. Aim for ≥4 kV at the far end for hard-to-hold animals; fix faults before letting stock in.

Maintenance & Troubleshooting

Keep your electric fence strong with a few quick checks. Cut or clear any grass and weeds that touch the wires—plants steal power from the fence. If the fence looks overgrown, mow the area or lift the bottom wire a little higher.

Good connections = good power. Make sure wire joins are tight and properly crimped. Around gates and corners, add cross-connects so power can travel both ways. Loose or twisted ties can drop voltage fast.

If the shock feels weak, think “ground first.” Poor grounding is the most common cause of low voltage. Check that your ground rods are long enough, well-connected, and in moist soil. Replace rusty clamps and tighten all ground leads.

Measure, don’t guess. Use a fence tester to read voltage at the energizer, halfway along the fence, and at the far end. This shows you where the power drops and what to fix next.

Quick fixes

Vegetation touching wire → mow or raise bottom wire.
Loose ties/joins → crimp properly; add cross-connects.
Low voltage → check grounding and energizer; measure at multiple points.

FAQs

Q1: How many wires?

Use 4–6 wires for a permanent goat fence. Start the bottom wire low and keep gaps small near the ground so goats can’t sneak under. For easy moves, use electric netting (portable rolls).

Q2: How high?

Make the fence about 42–46 inches tall. Keep the bottom wire ~6–8 inches above the ground, then space the rest evenly up to the top.

Q3: What voltage?

Aim for 4,000–5,000 volts on the fence line for goats. Check with a fence tester; thick coats and weeds can lower voltage, so keep it strong.

Q4: Can I use barbed wire as hot?

No. Don’t electrify barbed wire. It can tangle and injure animals and people. Use smooth high-tensile or netting instead.

Q5: Portable or permanent?

Portable: Electric netting is fast to set up and great for moving goats to fresh grass.
Permanent: Smooth high-tensile wire (4–5+ strands) lasts a long time and holds goats well.
