I’ve been working with electric fences for cattle pretty much all of my life. Ours are just the single strand of wire which is held up with insulated posts and has a battery supplying the power. Like everybody else I’ve looked at, and been tempted by, the fences which use solar panels to power them, but alas, the solar panels are too tempting for thieves. As it is, we use an old tractor or car battery and just recharge it occasionally.
People do ask if they’re dangerous. The answer is basically no. Apparently there is one death or serious injury world-wide per year, and that is a death involving an electric fence, not necessarily caused by one. Indeed to explain why, I’m going to quote one website, “the electric fencers used in agriculture put out high voltage (around 8,000 volts) this makes a very clear mental imprint that really gets the attention of the target. However they also reduce the deadly amps to a very low amperage of around 120 milliamps (It varies with manufacturers). This is 120 Thousands of an Amp (normal mains electricity is 13 Amps). It should not even kill a squirrel.”
