Let me Begin by saying I have a engineering & quality control background. I also realize that booby trapping is very illegal. So with that being said, I guess Im in need of some electrical advice. Im trying to booby trap a staircase. Using every other stair as a positive #1 or positive #2. I figured a double pole ten amp breaker won't kill anyone since it takes 11 amps minimum to be fatal. I also considered car battery but it releases hundreds of amps and there is no way to stop the shock. Now I was going to do 6 stairs. Each having an electrical rubber mat on the stair case, followed by a thick gauge sheet metal painted black to blend in. Each piece of sheet metal will have a bolt that protrudes underneath the staircase. Where I will jump positive #1 to stairs 1, 3 & 5. Positive #2 to 2, 4 & 6. Now this is obviously a fire hazard to some extent. N I also plan on installing ground rods. My question is... With the rubber mats its very unlikely the wood will heat up, correct? Arcing shouldn't be an issue, correct? Any positive feedback is greatly appreciated. Thanks guys.
