My car is parked outdoors, and I charge at a 14-50 outlet I had installed, also outdoors. A few safety questions: 1) Is it safe to leave the UMC plugged into the car in the rain? That seems like an obvious yes. But I want to double check. 2) Is it safe to to leave the UMC plugged into the outlet, but the Tesla-end hanging on a hanger, unplugged, in the rain? Or just in general to leave it that way, rain or no? 3) If the UMC is plugged into the outlet, with the Tesla-end not plugged in, how worried should I be if my 2-year old were somehow to get the Tesla-end and play with it? Is it impossible to get shocked from the Tesla-end?
