  • Watthour meter socket adapter
    Patent number: 4772213
    Abstract: A socket adapter for converting a conventional bottom connected watthour meter housing to a socket-type watthour meter housing. The adapter includes a housing having a watthour meter receiving portion including a plurality of electrical contacts which removably receive the blade terminals of a watthour meter. The contacts are connected via electrical conductors to terminals mounted in an integral terminal portion of the housing. A cover member is removably mountable over the terminal portion of the housing to provide access to the terminals. The terminal portion and the cover cooperate to form guide surfaces which direct the building conductors into engagement with the terminals within the adapter. A surge protector in the form of a pair of wires embedded within the peripheral surface of the watthour meter receiving portion of the housing are connectable through a connector mounted on the back wall of the housing to earth ground.
