We have all heard the horrors of tossing a toaster or other appliance in a filled bathtub. Well, I dont understand this now. A friend told me that he had to replace the shower valve in his tub. He replaced it, leaving his tools and a plugged in trouble light in the tub when he went out to the pump house to turn the water back on. The problem, he never turned the tub faucets off. When he got back in the house the tub was almost ready to overflow. and the trouble light was under water except the bulb which was floating and still lit. He said he immediately unplugged it. (the drain was shut because he was afraid a screw would go down). How can this be? Why did a breaker not trip? He said the socket of the light was filled with water too, because he took it apart to dry it out. He said his electric drill was also under water, but not plugged in. He took that apart too.
