The Triplett 9650 portable circuit breaker locator for finding and identifying breaker box switches from electrical outlets has an inductive tracer with audio and visual signals, a tone generator that sends electrical signals, and automatic shutoff. The tracer beeps and flashes a red light for clear indication of magnetic fields. The tone generator sends an electrical signal to guide the tracer to breaker box switches. The meter shuts off automatically after 10 minutes of nonuse to help extend battery life. The tracer and tone generator are each cased in acrylonitrile butadiene styrene (ABS) plastic for strength and light weight. The kit has a lifetime warranty. It is often used to identify breaker switches for labeling in home, commercial and industrial environments. The tone generator has two prongs that connect to a standard wall plug. Tone generator dimensions are 6 x 1.75 x .75 inches (H x W x D), and it weighs 2 oz. Tracer dimensions are 6 x 1.75 x 1.5 inches (H x W x D), and it weighs 3.6 oz. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The tracer operates on a 9V battery (not included). Wire tracers are used to locate wires in walls or underground locations. They identify circuit breakers and short or open circuits, which break electrical connections and prevent optimal electrical flow. Wire tracers are commonly used by home remodelers, and in the telephone, electrical, and video industries. Triplett manufactures test equipment for electricians, home security installers, and telecommunications technicians. The company, founded in 1904, is headquartered in Manchester, NH.
