viper load
n.— «Turning equipment off at the end of the day or when not in use. Most equipment and appliances keep a constant energy load so that they don’t have to warm up when they are turned on. This is often called a “phantom” or “viper” load and can add up to hundreds of dollars a year for a small office or store.» —“Small businesses can save energy with simple steps” Noblesville County Times (Indiana) Mar. 7, 2008.
