[QUOTE="bman4523, post: 1025926, member: 14632"] Great post. Here's my take as an licensed master electrician. As a point of reference, its takes about 800ma (0.8 amps) at 120 volts and 60hz across the heat muscle of a human to cause Ventricular fibrillation and cardiac arrest. Typically it takes considerable more potential than that to lethally circuit a person as the epidermis has a significant amount of resistance when dry. All three components of the electrical shock (amperage, voltage and hz) will have a bearing on its leathality. AC current is really what you would be after for your puposes. Getting a suffecint amount of that kind of sustained current to your trap location is a bit of a challenge apart from having utility power available. A remote power source like a battery and inverter could probably be assembled on a trailer and connected to the trap via long cord so you could conceal the power source. As for the trap, here is what I would aim for. Keep in mind that recent studys have found that in order to control or make a dent in local hog populations you have to get the older breeding hogs, which is where I think your idea has real merrit. They are the most savy and wary of the population and hardest to catch with the live pen type traps. So my prototype would entail remote monitoring like a simple security camera but would have to have night vision capability. This would be tied to something as simple as your cell phone for monitoring/triggering. This hardware has actually gotten much cheaper in recent years. My trap would consist of a supple wire mesh mat (think 40'X40' chain link fence fabric but with smaller openings ) that would be laid on the ground with the mesh openings about the size of a kernel of corn. The mat is then baited with corn or grain spread out over the mat. Envision the hogs standing on a conductor with all four feet and probably their snout pressed against it trying to root that grain out of the mesh. The mesh is thin and contours with the ground with some of the earthy material protruding through giving a natural feel. Now the other half of the trap would be a free standing camo colored pvc tubing structure that is supported by widely spaced pvc pipe legs giving a open sided structure. The top of this big pvc "table" is comprised of criss crossing pipes forming the top or canopy. The height would be 5 feet off the ground and would be a light weight snap together arrangement. Hanging from the top of the pipe canopy would be light strands of conductive material (think strips of electric fence tape, but camo colored) about 4 1/2 feet long that would mimic a leafy type over story. So the hogs enter the trap from any direction (no doors or passages, just a few widely spaced vertical pipe stands) wander around feeding freely, soon other more wary animals walk on the mat all the while your viewing from your smart phone or PC because you got a automated text message (trap activity!) from the game camera and when it looks like the hogs are all there you trigger the circuit remotely.
