ELECTRIC FENCING FAQ'S

What is an electric fence and how does it work?

An electric fence is a perimeter security system that delivers a short, high-voltage, low-current pulse through fence wires. When touched, it gives a sharp but safe shock that deterrs intruders without causing injury.

At the heart of the system is an energiser, which powers the fence and monitors its condition.

A reliable residential solution is the Nemtek Druid 18 LCD Electric Fence Energiser, designed for home and small business perimeters:

Is an electric fence safe for people and pets?

Yes. Electric fencing systems are designed to comply with South African safety standards. The pulse is brief and non-lethal, making it safe while still acting as a strong deterrent.

Correct installation and quality components are key to safety and effectiveness.

How do I know if my electric fence is working correctly?

Electric fences should be checked regularly to ensure they are delivering the correct voltage and that there are no faults on the line.

A very useful diagnostic tool is the Nemtek Fence Meter, which allows installers and property owners to quickly test fence voltage and identify faults:

What size energiser do I need for my electric fence?

The correct energiser depends on:

Fence length
Number of fence strands
Wall-top vs freestanding fence
Risk level of the property

For larger residential or light commercial installations, higher output energisers are recommended to maintain voltage across the entire fence.

Can electric fencing work during load shedding?

Yes. Most modern electric fence energisers operate on 12V DC and include built-in battery backup, allowing them to continue working during power outages and load shedding.

Keeping the backup battery in good condition is essential for uninterrupted protection.

Can electric fencing integrate with an alarm system?

Absolutely. Electric fences are commonly linked to alarm systems so that:

A fence tamper triggers an alarm
You receive alerts when the fence is cut or shorted
Monitoring companies can respond faster

Many energisers provide alarm outputs for easy integration.

What accessories are needed for an electric fence installation?

A complete electric fence system typically includes:

Energiser
Fence wires and insulators
Earth spikes
Warning signs
Monitoring and testing tools

Testing tools like the Nemtek Fence Meter are especially useful for ongoing maintenance:

Which electric fencing brands does RSEC stock?

RSEC stocks trusted electric fencing equipment from leading manufacturers, including:

Nemtek: Energiser units, monitoring tools, and accessories

Nemtek products are widely used across residential, commercial, and high-security installations due to their reliability and compliance with local standards.

Is electric fencing effective on its own?

Electric fencing is a powerful deterrent but works best as part of a layered security approach, combined with:

Alarm systems
CCTV
Access control
Automated gates

Together, these systems significantly improve overall security and response times.

How often should an electric fence be serviced?

Electric fences should be inspected:

After storms or strong winds
When vegetation touches the fence
At least once a year as part of routine maintenance

Regular testing ensures consistent voltage and early detection of faults.
