The movie "Dracula" was released on this day in 1931. In it, the famous vampire, when he accidentally opened his box in daylight, had a nasty shock. You could be in for a shock, too, if you open your circuit-breaker and have to guess which circuit to turn off for electrical work. Even if the box has general notations, like kitchen or basement, every outlet in that room might not be covered. This could lead to trial and error -- and a shocking conclusion. The answer: Have a friend go through rooms as you turn off circuit-breakers. When they tell you something's "on" or "off," note what they control on a label placed by each switch, for future reference. Keep a list in your house file, too; it's easiest when you first move in, no resetting clocks and VCRS all day. If you're home alone, and without a friend to help, use a radio. Turn it on loudly, move it around and listen for it to go off when you flip a breaker. And that's the On The House tip for today.
