An electric fence is cheap to run. You will only spend a large amount to install it. How much you spend to install will depend on the size of your plot.

It costs 72 cents to $1 to run an electric fence per month. This is the cost you will incur if you install a 10-watt charger on your fence. Most electric fences run on 10 to 50-watt chargers. An electric fence doesn’t consume power until it is touched. Power only passes through the fence.

An electric fence can be used in both urban and agricultural settings. It does a proper job providing security from outsiders and keeping animals and pets from straying.

How Much Does An Electric Fence Cost To Run Per Month

The Capacity Of Your Charger or Energiser

Always purchase a charger that is larger in capacity than you need. A large capacity fence energiser ensures that your fence receives enough power for it to work.

Additionally, if you ever need to extend the fence, you will not have to buy a new charger.

Installation Of The Components

When buying components for your electric fence, make sure that you install high-quality components. High-quality components ensure that your electric fence is durable and works well. The high-quality components ensure that the fence is long-lasting and help to save you money.

Purpose Of The Fence

If you need an electric fence to keep your animals from straying, you will have different power needs from when you need an electric fence to protect your premises.

You may need a high voltage for a home than you need to fence in animals. Depending on the purpose of your electric fence, it may cost more to run it per month.

How Much Voltage You Need It To Hold

A high voltage produces a strong shock when the fence is touched. A high voltage will easily keep animals and humans from touching or coming near the fence.

Depending on the purpose of your fence, you will have different voltage needs. Agricultural fences may need a higher voltage than homestead electric fences.

How To Properly Maintain An Electric Fence

To ensure that your electric fence remains cheap and affordable to run, you need to keep it properly maintained.

Voltage Flow

One of the main factors in electric fence maintenance is keeping the proper voltage flowing through the wires. To do this, you must have a voltmeter also known as a fault finder. The voltmeter checks how much voltage is in the wires of your fence. With the right voltage, you can keep your fence within acceptable monthly consumption of power.

Earthing Cable

Make sure that the earthing and the insulators are fixed properly. This will keep the fencing running properly.

Regular Inspections

Inspection ensures that your fence works well for longer. Inspect your fence to confirm that the wires of the fence are still strong and tightly fixed in place.

Debris removal

Debris on the fence prevents it from working effectively. Branches, twigs, and trees on the fence can cause power to flow slowly or less than required through the fence. Do a fence walk once per week to ensure all is working well.

How Long Does Electric Fence Last

With proper maintenance, your electric fence can last an average of 10 to 20 years. To get this lifespan out of your fence, ensure that you have the right wires on your fence. Stainless steel wires are the best wires to use for a long-lasting electric fence.

Components Of An Electric Fence

The components of an electric fence depend on the type of power it runs on. An electric fence can run on solar power, mains, or a battery.

An electric fence running on mains power consists of an energiser or charger, an earthquake stake, cut-out switch, posts, insulators, fence wire, cut-off switches, and fence posts.

All these components work together to ensure your electric fence works as it should.

If you are using a battery or solar-powered electric fence, you will need a solar charger and a battery system.

How Does An Electric Fence Work

For an electric fence to work efficiently, the charger or energiser converts the power it gets from its source to a high voltage pulse. This pulse is released into the fence wire and it opens and closes the gate. This high voltage pulse can be felt when you or an animal touches the fence.

For your fence to work effectively, you should ensure that you have high-quality components. Also, ensure that the earthing is well connected to the ground and installed away from tree roots and foundations of buildings.


Yes. Rain affects an electric fence by reducing the amount of voltage passing through the fence. One way to eliminate this problem is by using a larger-capacity charger. A high voltage capacity charger will ensure that enough voltage is passing through the fence wires.

Additionally, check that the insulators are properly installed and that they don’t touch any plants. Cut any plants near the insulators of your electric fence. Insulators should not touch any trees or flowers. It will reduce the effectiveness of the fence when it rains.

An electric fence can easily kill you based on the voltage passing through the fence. The higher the voltage the more likely the fence is to kill anyone or animal that touches it. How much voltage is passing through an electric fence is determined by its purpose. An agricultural electric fence has a low voltage as you don’t want to kill your animals. You just need to shock them enough to avoid the fence.

A residential electric fence may have a higher voltage passing through to shock and even kill intruders.

You need at least three grounding rods on your electric fence. The correct grounding you need to install in your electric fence is at least 6 feet long. Install the grounding rods 10-12 feet apart from the starting of the fence.

Also, depending on the size of your fence, the more grounding rods you need. Grounding rods increase the shock potential of your fence. Thus, they are essential parts of the electric fence.

When installing ground rods, ensure that they are far away from telephone and other utility lines which can cause interference.

How Many Grounding Rods For My Fence To Work Properly

A joule measures the amount of energy produced by a current of one amp at a one-volt potential. One watt of power produced per second is equal to one joule.

Amps measure the amount of electrical current passing through a wire. The more the amps, the higher the current passing through the wires. The higher the current passing through your fence, the stronger the shock it produces.

Volts or voltage is the force with which electricity is passing through the wires of the fence. The higher the voltage the higher the amount of electricity passing through the fence.

Yes, an electric fence can start a fire.

One way of preventing your electric fence from starting a fire is by proper maintenance. First, ensure that the fence is properly installed with the right amount of grounding rods and proper voltage.

Second, ensure that no plants are growing or falling next to the fence. Especially during the dry season, an electrical fault can easily cause a fire. The dry vegetation next to the fence can spread the fire quickly.

With the right skills and tools, you can easily DIY your electric fence installation. You need the right tools and materials to install an electric fence by yourself. You need to choose the fence and fence wires, you also need proper posts, wire, and insulators before you start.

It is better and easier to hire a professional to install your electric fence for you. They will advise you on the best fence and fence materials to use for your fence. And, they will do it fast and expertly.
