This is all 12 volt DC current, guys. A whole different animal than Alternating Current. If it wasn't, we would all fry ourselves everytime we dropped a trolling motor in the drink. I wouldn't throw my grandkids into the water where any type of sketchy electrical circuits were present. Old docks scare the bejeezus out of me. I've seen some that I wouldn't even grab the handrail of. Say what you like about the COE's stand on no new A/C supplied docks, but I'm kind of in agreement with them.
