ABSTRACT:
A method and means for preventing reversal of the orientation of an electric utility meter in its base socket. A first tab is attached to the rear face of the meter and a second tab is attached to the front face of the base such that a conflict between the two tabs develops if reversed assembly of the meter and socket base is attempted. In one embodiment of the invention, the first tab, consisting of a short metal rod, is welded to a vertical edge of one of the meter plugs and the second tab, consisting of a metal sleeve, is mounted to the base socket receptacle which is diagonally opposite to the receptacle in which the tabbed plug normally fits.
