That electric fencer needs it's own grounding electrode system!<br>
<br>
Unlike the premises grounding system, where there's normally no voltage present, the fencer's<br>
ground completes the circuit.<br>
<br>
I have measured over 12,000 volts on our farm fencer grounding conductor....I have learned not to<br>
touch it....had to try it 2 or 3 times to be sure though ;-)<br>
