ABSTRACT:
A construction for the housing of a unit which has a pair of male supply terminals and a differently oriented male ground terminal, which precludes improper mating and potential shock hazard. The construction comprises a shroud surrounding the housing surface from which the terminals protrude and which corresponds to the female outlet housing contour and thus permits insertion of the terminals in only the correct position.
