So I wired 11 4' pieces of flexwatt for my shelf, and taped it onto the shelf using foil tape. I test each piece to make sure it warms up, and also to test for conductivity. At one point I got the foil tape too close to the exposed solder and got shocked (oops, lesson learned)


So I wired everything up, soldered the wire to the expose flexwatt, and taped it all down, everything warmed up and was not shocking...


So now that I have it in the shelf, it was working fine for several days, no shocking, but tonight my wife said she was checking and got shocked when placing her hands over the foil tape.... not on one shelf, but on 10 of the 11 shelves!

What could be going wrong here? It worked fine at first, I used black tape on every exposed piece, and the foil tape is only touching the plastic covered portion.

We had left the humidifier running and the room was up to 50-60% humidity but I dont see that being the cause.

Any ideas? Im kinda confused as i dont see where the juice could be coming from
