I'm not an electrician, so I apologize if this is a dumb question, but I have a related question. What about swimming near a circulator (like the ones used to circulate water around your dock in the winter)? Those are plugged into shore power, with the cord running directly into the water. Obviously, nobody is swimming in the winter, but would it be unsafe to swim in the water with one of those plugged in (if, for some reason, you still had it plugged into power in the spring)?
