ELECTRIC FENCE Q & A
HOW DOES ELECTRIC FENCE WORK?
Tis fence works by having an energy source that releases a pulse onto an insulated fence line about once every second.
contact with the fence, the circuit is completed, and the animal receives a "shock." Te current flows from the charger, down the fence line, to the animal, then finally to the ground.
When an animal makes
your choice. At RAMM we carry insulators for wood posts, PVC Sleeves, steel T-posts and Round Rods up to 5/8" in diameter. When using electric fencing for horses we recommend that your posts are spaced no further that 12-15 ft. All corner and end posts should be braced and concreted.
WHAT SIZE CHARGER DO I NEED? A basic rule to follow is: 1 Joule = 6 miles of fence. That is only true in a perfect situation where you have perfect climate, no excess vegetation growth and no corrosion of wires. In most situations you should figure 1 joule for every 1-2 miles of fence.
WHAT ARE JOULES? A joule is a measurement of electrical energy. 1 Joule is equal to 1 watt of power for 1 second of time (watt x time = joules)
WHEN IS ELECTRIC FENCING NEEDED? Does your horse lean, chew, crib, charge your fence or is overly active? Are your fences difficult to see? You will need electric fencing.
NUMBER OF STRANDS? The number of strands of Electric Fence is a matter of your particular application. 65% of Electric Fence users install 3 strands. 4 strands are most commonly used when fencing along busy roads, around crowded areas, smaller paddocks, aggressive animals or foals. Always consider the rail or strand spacing most appropriate for your particular needs.

WHAT IS THE DIFFERENCE BETWEEN LOW AND HIGH IMPEDANCE? Low impedance fence chargers have the capability of increasing their energy output as the fence load increases. This means that if weeds touch the fence and draw voltage and
amperage to earth, a low impedance charger will begin to produce higher amounts of energy or joules. These higher energy levels will overcome the voltage and current loss caused by weeds and maintain energy levels on the fence for controlling animals. High impedance fence chargers do not have the capability of increasing their output energy as fence loads increase, and cannot overcome high levels of fence load. They "short out" when too many weeds touch the fence.
HOW MUCH SHOCK DO I NEED? Experience has taught us that short- haired animals require a minimum of 2000 volts to control them: long- haired animals require approximately 3-4000 volts.
WHAT IS THE PRIMARY FUNCTION OF THE GROUNDING SYSTEM? The grounding system is required to ensure maximum performance and
that your shock is only as good as your grounding system and your ground rods complete your circuit. We recommend at least three ground rods, 5' long and spaced 10' apart.
