1. Electric Fence Chargers Guide 
If you don't already know how voltage, joules, and impedance relate to electric fence chargers, please read "Why is voltage important?" "Why are joules important?" and "What is low impedance?" in the Answers to Frequently Asked Questions page. In general, the low impedance electric fence chargers that we offer are safe because the pulsed nature of their charge means a shocked person or animal has no difficulty letting go of the charged wire. Even so, if the charged wires are very low there is always the remote possibility that a pet will somehow get entangled in them, or (if a powerful charger is used) there is some chance that a single pulse might prove strong enough to harm a bird, pet, or even a crawling infant that happens to come in contact with such wires. Thus, whenever low electric fence wires (as low as 4 to 8 inches above the ground) are used to keep small creatures out of gardens, only demonstrably pet-safe and child-safe electric fence chargers should be used. Since major weed burdens should be avoided, a weed barrier (black polyethylene film covered with pine bark or wood chips) should be placed under the electric fence wires, and potentially encroaching vegetation should be removed every week or two. Also, a charger that copes well with weeds, such as the Dare Enforcer 300, should be used. If only deer control is involved, then the electric fence wires protecting summer gardens can be higher (generally 24 to 36 inches above the ground) and stronger electric fence chargers can be used. However, electric fences protecting residential gardens are generally short enough so that keeping them baited and weed-free is practical; and if the weed burden is light, then mild to intermediate electric fence chargers like the Parmak Solar Pak 6 can work well. |
