How many joules does a cattle fence need?
Gerrish recommends 1 joule of output per mile of fence, regardless of how many strands of wire. If there's a total of six miles of fence, it requires a minimum of a 6-joule energizer. via
What voltage should my electric fence be?
In fact, anything between 5,000-9,000 volts is ideal, but your cattle species and temperament will determine the best voltage. I assured Bob that as long as his cattle were respecting the fence, he didn't need to worry. via
How many joules does it take to keep a bear out?
Bears are more likely to pay attention to an electrified fence that delivers a painful shock. For deterring bears in developed areas, your energizer will require a minimum joule rating of: 0.7-1.0 stored joules or 0.5-0.7 output joules. via
Is 1 joule a lot?
This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules. via

An object which impacts a human is considered a 20% chance of being lethal with a head strike if its energy is greater than 80 Joules. It has a 90 percent chance of being lethal with a head strike. via
How do I increase the voltage of my electric fence?
Make use of your fence's cold wires (assuming you have some steel posts) as extra earthing to improve the voltage at the end of your electric fence. Connect them all the way throughout your fence starting from the main energizer earth stake. This means taking an earth wire and a live wire under every gate. via
Can an electric fence hurt a child?
Many people wonder if they will get hurt by touching an electric horse fence. RAMM's fence chargers are low-amperage and high-voltage, which produces a shock that is not harmful to humans or animals. People with heart conditions, children, or elderly should avoid touching electric fences. via
Can I check an electric fence with a multimeter?
The Digital Voltmeter can help you locate the source of a short by measuring the voltage in the fence line. You can also use the Neon Fence Tester, although it is not as accurate. You will see a reading on the screen - on a good electric fence line this should be in excess of 6,000 volts. via
What smells do bears hate?
Bears also dislike the strong scent of pine-based cleaners, but avoid using anything with a fresh, lemony or fruity smell. And never mix bleach and ammonia; the combination produces fumes that can be deadly to both people and bears. via
Will an electric fence deter a bear?
A properly installed electric fence will prevent bears from accessing areas of your property and can be an effective long term solution to preventing bear problems. Electric fencing can be used in many situations to effectively deter bears and other wildlife from various attractants. via
How many joules is in a Volt?
The Voltage Unit
Where: voltage is in Volts, J is the work or energy in Joules and C is the charge in Coulombs. Thus if J = 1 joule, C = 1 coulomb, then V will equal 1 volt. via
What is the formula for 1 joule?
1 joule of work = 1 N of force x 1 m of distance
In the English system of units, where force is measured in pounds, work is measured in a unit called the foot-pound (usually abbreviated ft-lb). via
Which is another form of 1 joule?
A watt-second (symbol W s or W. s) is a derived unit of energy equivalent to the joule. The watt-second is the energy equivalent to the power of one watt sustained for one second. via
How many joules is a punch?
The kinetic energy of a punch varies greatly. While beginners might only be able to muster a measly 37.5 joules of energy, experts can deliver over 400 joules, an amount roughly equal to getting shot by a handgun! via
Is 1000 joules a lot?
A unit with up to 1000 joules of surge protection is adequate for these small electronics. A surge protector with 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers. via
How many joules does it take to move 1kg?
Unit of energy is Joules (J) or Kg m^2 /s^2. Therefore the energy required to lift the object of mass 1kg to the height 1 m is 9.8 Jules. via
Why is my electric fence not very strong?
Poor grounding is one of the most common faults in electric fencing systems. If the ground is not completed correctly, the energizer cannot operate at is maximum potential. This could be accomplished by driving three ground rods that are each eight feet long into the ground at least 10 feet apart and attaching them. via
Can you hook 2 electric fencers together?
No. The components in our energizers are designed for specific voltage and current requirements. Hooking up two or more energizers to the same line will eventually destroy the energizers. via
How do I energize my electric fence? (video)
What happens if a child touches an electric fence?
If a small child touches an electric fence, the “unpleasant shock” an adult feels, can be traumatic to the child. A simple precaution would be to ensure an adult is always present when your child is in the yard, or simply turn the fence off until play-time is over. via
Can a bird sit on an electric fence?
Birds can land on electric fences and they normally won't feel any ill effects. They don't create any voltage potential and don't provide any path to the ground, hence they don't get a jolt. Their feet are close and there's so little voltage potential between them that no current really flows through their bodies. via
What does touching an electric fence feel like?
What happens if a person or animal touches the electrified wire of the fence? The person or animal will feel a rapid electrical shock, which may range from a small buzz to a very painful jolt. The electricity is discharged in less than one second and is usually DC (direct current). via
How many amps are in an electric fence?
Amps are what kills. Electric fence energisers put out high voltage (around 8,000 volts), but very low amperage or current (around 120 milliamps). This is 120-thousands of an amp. via
How do you test an electric fence without getting shocked? (video)
How can I test my electric fence without a tester?
Does human urine attract bears?
Yes, Bears Do Seem to Be Attracted to Human Urine
Bears have incredibly powerful smelling capabilities, and this means that they will be able to smell urine very clearly even if you try to dilute the smell. It simply isn't a good idea to try to pee too close to your campsite if you want to keep things safe. via
Do bears hate apple cider vinegar?
Ammonia or cider vinegar- soaked cloth in trash can or hung on doors and windows can deter bears. The smell of Lysol and PineSol also repels bears. via

What is best wire for electric fence?
Aluminum wire is the best for carrying a charge. Aluminum conducts electricity four times better than steel wire. While it will cost more, aluminum wire does not rust like un-galvanized steel wire. via
How many ground rods do I need for electric fence?
A general rule is to install a minimum of 3 feet of ground rod per joule of output capacity. A 15 joule fence charger will require a minimum of 45 feet of ground rod. These rods must be installed at least 10 feet apart from each other. via
Can animals sense an electric fence?
With the super-hero-ability ears that dogs are equipped with, it's no wonder they're able to hear the electric currents buzzing through the electric fence you've hooked up. Dogs can hear about twice the Hertz frequency that people can - humans are stuck at a mere 20-20,000 hertz. via
