Do place ground rods in permanently damp ground. About 95 percent of all electric fence problems are due to poor grounding.
Don’t use an energiser that isn’t EU approved. EU approved energisers are certified safe for both horses and for people.
Do check woven horse tape fencing regularly — wind flutter can break the wire conductors making the electric fence ineffective. Large diameter, braided electric rope is visible, strong, and durable, and suitable for use as a permanent perimeter fence. Lasts longer than, and cheaper than Tape.
Do install an earth return fencing system in dry climates or very sandy soil is in your area.
Don’t plan your fence line to run through places where your horses habitually roll.
Do check your fence voltage regularly with a voltmeter. Ensure the voltage is between 5,000 and 9,000 volts.
