From Dog Turds to Pissing on Electric Fences in Five Comments or Less

Bill gets down to brass tacks; exactly how hard will a predator rated electric fence shock you if you piss on it?


How do they measure fences? Volts, amps, joules? What sort of typical voltages do they run? It felt like anywhere from about 100 VAC for the garden variety fences up to maybe 150-200 VAC for the really hot fences. But if you're talking a 2" spark, that's gotta be up in the kilo-volt range, so I guess the current is in the micro-amps.

They are capacitor discharge about once per second. They go 'thunk' every time the fence is charged in a short pulse.
The output is measured in joules.

9000 volts at 1.4 joules, Bill.

1.4 joules is 1.4 watt-seconds, or enough energy to lift an apple about 4 feet. But since at 9Kv it's easily enough to overcome your bodies resistance, it's gonna feel like it could lift YOU up about four feet. Fortunately, the amperage is almost too small to measure, so it's not gonna kill you unless you happen to have a heart attack from the jolt.

9000 volts, that WILL get your attention!
