Abstract
Abstract A watthour meter socket adapter includes a plurality of rigid electrical conductors non-attachedly disposed in a housing. An electrical contact is mounted on a first end of each electrical conductor and is positioned within the housing for receiving a blade terminal of a watthour meter therein. A second end of each electrical conductor extends externally of the housing for insertion into terminals mounted in a watthour meter socket. An insulating sleeve mounted in the housing surrounds the portion of the electrical conductors extending externally of the housing, with the second ends of the electrical conductors extending outward from the sleeve. An electrically insulating plate is mounted within the housing spaced from a base of the housing. Apertures formed in the insulating plate receive individual electrical contacts on the conductors for positioning the electrical contacts and the electrical conductors within the housing to receive a blade terminal of a watthour meter.
