RAMM offers a large selection of plug-in chargers, ranging from chargers that can offer coverage for up to 750 acres all the way down to an electric charger that covers up to 50 acres.
When looking at electric fence chargers, we always recommend that you protect your investment, and lightning protection is essential to protecting your investment in fence chargers. A good grounding system must be installed. A few feet of rod in the ground is not enough except for light portable chargers. If there are a lot of shorts on the fence and/or the ground is very dry, it is not uncommon to need more than three 5’ ground rods. Ground rods should be ten feet apart and at least thirty feet from other existing grounds. Stay away from water pipes (especially those going to drinking areas) or buildings where an electric charge may affect livestock (like milking areas) or people. The non-electrified wires on a fence can be connected to bring distant ground rods back to the ground terminal of the charger. Some installations have required over ten 8’ ground rods.
RAMM TIP - To determine what charger to use for your electric fence: length x width = square footage. The square ft. divided by 43,560 = the number of acres. Acre listings are given for each charger.
