The Nemtek Double Pole Lightning Protection is the lightning diverter that sits between an electric fence and its energizer. Nemtek energizers have lightning protection built in, but a surge coming down the fence wires can still reach the unit. This external protector has a built-in lightning inhibitor that stops the surge getting to the energizer and a built-in diverter that sends it into the earth spikes. Nemtek calls for one unit on a single zone energizer and two on a dual zone, fitted between the energizer and the start of the fence, closer to the fence, and no more than 2m from the earth spike.
What's in the box
- Double Pole Lightning Protection unit (EA-LIDII)
- 2 mounting screws
- Tool for the HT cable nuts
How many do you need
One per fence zone. The Wizord 4i, Druid 15 LCD and Merlin Stealth M18S are single zone energizers and take one unit. The Merlin Stealth M28S is dual zone and takes two, one on each zone's HT cable.
Where it goes
Nemtek's manual puts it between the energizer and the beginning of the fence, closer to the fence than to the energizer, and as close as possible to the earth spike, never more than 2m away. It mounts on a flat face with the two screws supplied; the screw holes are inside the cover. The HT cable connects between the washers on the unit and the nuts are tightened with the tool in the box. HT cable and earth spikes are not included.
Arc gap settings
The arc gap has three positions, set by moving the bottom stainless steel plate: 14.5kV, 16.0kV and 18.5kV. Nemtek recommends the 14.5kV position for most installations and says the environment may call for position 2 or 3. The installer sets it.
Build
UV-stabilised plastic housing with stainless steel components, rated IP54 and weighing 0.5kg, made for use outdoors near the fence. Nemtek does not limit it to storm-prone areas: it fits any security energizer installation. The fence and its mains connection must be installed and certified by a registered electric fence installer, who issues the electric fence system certificate. Alectra supplies the equipment only.
Key features
- Inhibitor and diverter in one. A built-in lightning inhibitor stops the surge reaching the energizer and a built-in diverter sends it into the earth spikes.
- One unit per zone. One for a single zone energizer such as the Wizord 4i or M18S, two for a dual zone M28S.
- Three arc gap settings. 14.5kV (Nemtek's recommendation for most installations), 16.0kV or 18.5kV, set by moving the bottom stainless steel plate.
- Sits by the earth spike. Fitted between the energizer and the start of the fence, no more than 2m from the earth spike.
- UV-stabilised housing, stainless steel parts. Made for use outdoors near the fence, rated IP54.
- Screws and nut tool in the box. Two mounting screws and a tool for the HT cable nuts come with it.
- 1 year warranty. Nemtek covers its fencing components for one year from the date of sale.

Manuals and documents
Questions people ask
Nemtek builds lightning protection into its energizers, and its manual says this external inhibitor and diverter reduces the chance of a surge coming through the fence wires reaching the energizer. It is meant for any security energizer installation, not only storm-prone areas, and on the Highveld the summer storms make it worth fitting.
Between the energizer and the start of the fence, closer to the fence than to the energizer, and no more than 2m from the earth spike.
Two. Nemtek specifies one unit per zone, so a dual zone energizer takes two.
Nemtek recommends the 14.5kV position for most installations. The 16.0kV and 18.5kV positions are there for when the environment calls for a different setting, and the installer decides.
No. The box has the unit, two mounting screws and a tool for the HT cable nuts. HT cable and earth spikes are sold separately.
No. This unit handles surges coming through the fence wires. Nemtek's manual says protection for surges through the mains is a separate product, which we do not list.
Yes. It has a UV-stabilised plastic housing with stainless steel components and is rated IP54, and Nemtek makes it for use outdoors near the fence.
