An 88B unit is an unusual energizer in terms of circuit design and function. Though only a 5.5 joule unit, even at low setting, the joules that it actually delivers to the point of animal contact greatly exceeds that of much larger units when the total fence circuit resistance is high.
How many volts is needed for sheep?
It has been stated that 3,000 volts is needed for sheep, 2,000 for cattle or variations on this theme. Such statements need to be read with much more understanding than is usually provided. The same sheep fence in my area in the early morning in June may read only 1,000 volts at 7 a.m. and 3,000 plus volts at 5 p.m. At both times, the fence is probably delivering effective energy and voltage to an animal.
How many volts is enough to kill an animal?
In fact, 600 volts may be enough (Remember, that animals have been killed by 220 volt circuits when touching alternating current, so, we know that 220 volts are enough to "open the door" to the passage of energy through flesh in optimum conditions.) At 5 p.m. the grass is dry, and so are the animals' hooves and hair.
