Fences: (Obviously this depends on your exact set up)
Kill power to the charger.
Cut any part of the connection. Everything distant to the charger is dead. (Some circuits are complicated and beyond my understanding. The simple start to end electric circuit is what I'm thinking of here)
Wait for a dry dry month- the ground rod won't work and the shock is null.
Wait for a wet wet day- all the weeds and tree branches which are wet will sag and touch the fence and dissipate the charge. Obviously requires minor neglect from the ground keepers. But extra wet days can cause extra sag. Same with ice pulling branches down, then starting to melt...
Plow right over/through it. Most shocks come in pulses (ex- every 6 seconds) so you get hit once or maybe not at all if you're quick. Again, depends on type of fence.
Really thick clothing.
Do you know what shock level they use to keep ppl in? I've hit some hot hot horse fences, but if I had to plow through something I'd go for it. And if the charge isn't that strong, most wire cutters have rubber handles already. You could add a simple rag for extra insulation. Depending on the volts you'd get a small or no shock.
Old rusty spots won't conduct charges as well- again, everything downstream will be muted.
Heck, on a wet day (assuming maintained ground but a fair amount of wet grass) get a wet sheet. Sling it over the fence and have a fair bit touching the wet grass. Say it with me: Everything downstream is muted
And regardless of faults, the end of the fence line will be weak if a proper charger for the miles of fence is not used. But usually the planning is done right and the difference is null or minor. And it's very easy to check.
But whatever you do, do not, ever, accidentally back into a fence elbow first. You'll hit your funny bone, which is actually a nerve, and the volts will fly up that nerve and you will not find it at all humorous. Ask me how I know
