Sorry, I got off on a tangent with the pool pumps and lights.
This originally started with codeman talking about using a sump pump as a washdown pump on his dock, that's likely a submersible 120 volt pump. It wouldn't be practical to use 12 volt pump.
My point was that you can use high voltage, submersible devices safely. But to be safe they have to be wired and installed correctly. Cutting off ground lugs defeats one of the safety features. I know it happens, all my Dad tools have the lugs removed.
I'm done beating this dead horse.
