Professional Tips for Power Surge & Lightning Protection

Save dogs from Power Surge

As you become habituated to a pet fence system, you do not want it to either malfunction or stop altogether, for even a day. But things happen and lightning strikes and power surges are two concerns to deal with.

Lightning bolts can instantly send a shocking amount of electricity inflow, driving the whole mechanism to a complete shutdown. 

A power surge and lightning protection unit comes into effect, exactly during these times. This unit diverts the excess power to save the transmitter. We have laid out the most comprehensive guideline on surge protection devices.

Let’s dig deep into the world of elementary electronics.

What Is A Dog Fence Surge Protector?

A dog fence surge and lightning protector is devised to defend the dog fences. A pet fence surge protector introduces unique functions.

It combats spikes or direct surges coming in from the boundary wire on your electric dog fence. It has barely any resemblance to the usual household surge protectors, known also as surge arresters. Lightning arresters safeguard the plugged-in television or computer.

The surge protection devices are only designed for a dog fence. It promises two layers of protections via a single system.

What does the surge protector save?

All electric dog containment systems must have external surge protection to properly earth the installation and shield it against outside surge sources. The lightning protector guarantees two levels of safety.

Primary Protector:

Bypasses lightning surges from outside wiring.

Secondary Protector:

Skirts AC surges to the ground via house wiring. It defends the fence electronics such as the transmitter and your house wiring. A lightning bolt might strike on or adjacent to your property.

Oftentimes, it gets picked up by the fence wire as it could be powerful enough to catch up the dog fence perimeter wire. 

This sudden flow of electricity travels up the fence wire via the transmitter and right into your home. An eventual flood of current sends the transmitter into overdrive.

Such an incident can damage the dog fence transmitter. This is the time for the surge protector to flash into action. 

The device also acts against occasional AC power surges, happening down your house wiring. AC power surges take place in the power line of your house. It also requires defence from the surge protector.

You must examine all dog containment systems, regarding lightning surge protectors. If not, the system might be a recipe for disaster.

Since electronic fencing surrounds a perimeter, it has to be earthed or earth ground to prevent catastrophes.

How are lightning protectors designed?

Basically, the lightning protector plugs into a wall outlet. Usually, there are two outlets on the opposite sides of the lightning protector. One goes to the fence.

The other provides an additional outlet so that you are not losing an outlet by having the surge protector plugged in. 

The fence terminals are placed on the bottom side of the device. Here, you connect the transmitter wire to the black terminals and the fence wire to the red terminals.

The terminals could be in any other color as well and you have to resort to the device manual. 

Normally, these two devices, protector & transmitter, will be mounted together side by side. The fence transmitter hangs on the wall and the protector is plugged into a wall outlet. 

The AC power adapter for the fence will be plugged into the side of the lightning protector. So the machine is designed to guard your investment.

How do the lightning protectors work?

Plug the protector into a wall outlet and the transmitter into a convenient piggyback outlet. In the wake of either a powerline surge or a lightning strike surge, the lightning protector absorbs or swallows the surplus hit.

This extraordinary inflow of electricity triggers an automatic disconnection of outgoing power. The disengagement, in turn, dissuades or cuts off the surge from travelling to the transmitter or your home powerline.

You have to maintain a safe distance from inexpensive surge protectors. They may not rise up to the occasion in shielding the transmitter. Cheap lightning protection system often carries no insulation mechanism for the boundary wire.

Is surge protection necessary?

The surge protection is absolutely mandatory for all underground pet fence kits. Imagine the electric dog fence system as a huge antenna surrounding the property. It facilitates a radio signal traveling through it.

Let’s face it, the finest dog fence wire is made of copper. This metal is highly conductive. There are several benefits of it.

Instrumental safety:

You no longer wish for a physical toil all over again in setting up the system. An efficient lightning protector saves the transmitter and the whole installation.


A premium in-ground pet fence system takes money out of your pocket. You have already invested a pretty penny for it. You do not want to spend for another lightning protection system again.

Simple installation:

The best surge protector setting up does not require any professional assistance. Easy plug in into the outlets gets you going in this regard.

It is one of the fastest, cheapest, and easiest ways to guard your dog fence investment. Luckily, most brands claim to have it integrated with the package.

But you must have a watchful eye on this specific issue so that you do not need to regret in future.

If the integrated device is not up to the mark, you can effortlessly choose an upgraded fence protection unit. Low quality devices could easily end up being fried in the face of a tough challenge.

In case you are planning on a fence customization, check out the standard of this device too.


A sudden lightning strike can cause outstanding power surges or spikes even several miles away. It has no precise directions and consequently, no one can predict its path. Thus it might cripple your in-ground electronic dog fence.

Barring rare exceptions, almost all transmitter damages can be traced back to power surges or spikes originating from the boundary wire and not the power adapter.
