Electric Fencing: DANGER 10,000 VOLTS

Well once again I got hit by my own electric fence, this time while "gapping" it to test the potential on the line (a rough estimate of how many volts are on the wire judged by the length of the spark it throws). I got hit while throwing the disconnect, and for the instant the line was hot it hurt worse than the time I touched one leg of a 480 at work (that's 277 volts AC)!
Here is a brief video of a half-inch spark drawn across the disconnect switch. Enjoy what it LOOKS like (hopefully you never get to find out what it FEELS like)!
