Depending on which fence charger/controller unit one installs the shock delivered is anywhere from a mild “zap” to discourage rabbits to a “ZAP” that will leave a full-grown cow or horse quivering on the verge of collapse. If one would install a fence controller rated for “up to 20 MILES”,that’s right, miles of fencing, but hooked to the few hundred feet of a yard fence ,anyone touching it will likely be knocked down .Since the intruder was able to run away the protective mother must have installed a unit of the weaker rating.
Civilian fencing is sold only to control livestock or four-legged predators.If it deters two-legged predators,all the better.For lawsuit prevention,one should never remark to ANYONE that your electric fence is for any purpose other than keeping the cows in or keeping those darn deer,etc. out of the garden,prize rosebush or whatever.
An old fellow in my area “saved money” by simply hooking a wire to his fence(which is/was on insulators ) and plugging directly into the household socket. 110vac with only the house fuse to limit the current.It would have killed anyone/any animal tangled in the wire.Only luck or Providence prevented the tragic death of some person or valuable animal. You know he didn’t put up the “warning:electric fence” signs required in some places.
I was mighty close to doing the same thing until it was explained to me that it would likely kill the perp. There had been a rash of bicycle thefts in our town, including one of my sons’ bikes from our front lawn in broad daylight.
I wanted to wire a bike and wet the ground, to kinda’ get the thief’s attention. But the death penalty for bike theft is a little over the top.
I know what happens when one urinates on an electric fence. Oh youth. The follies of youth.
