Combined pilot light and ground testing assembly

摘要

A combined pilot light and ground testing assembly for conventional 120 volt A.C. circuits is secured in the front panel of an electric console, secured to the male A.C. plug at the end of a cable, or secured to other appropriate equipment. It includes a pair of lamp chambers spaced from a third lamp in rectilinear alignment. When both of the juxtaposed pair of chambers are lit as a dual pilot light a perfect condition exists. Any other combination of lighted lamp chambers indicates an unsafe condition in the circuitry.
