Abstract
A faulted circuit indicator unit for detecting an abnormally high electric current in an overhead cable includes a substantially rectangularly-shaped housing formed of front and back walls, opposed side walls, a closed bottom wall, and an open top mouth portion. Current sensing circuitry is disposed in a cavity formed in the housing for detecting the high current in the cable. An indication device is joined to the closed bottom wall of the housing and includes a visible indicator responsive to the current sensing circuit to produce a visual flashing light in the presence of the high current which is visible through a small aperture formed in the bottom wall thereof. The indication device is formed of an opaque hood whose central portion is connected around the bottom wall of the housing and a transparent stem joined also to the central portion of the hood and extends downwardly therefrom through which the flashing light is transmitted radially outwardly in all directions.
