ABSTRACT:
A terminal cover removably mountable on a watthour meter socket adapter includes an arm having an outwardly extending flange which is disposed in proximity with a sealing ring when the sealing ring is disposed about the mating mounting flange of a watthour meter and the rim of the socket adapter to lockingly mount the terminal cover on the socket adapter via the lock device carried by the sealing ring. In one embodiment, the flange on the arm has a predetermined length to engage a notch in the sealing ring to prevent rotation of the sealing ring. In another embodiment, the length of the flange on the arm is selected such that the flange lies between the sealing ring and the socket adapter housing to lockingly retain the terminal cover on the socket adapter housing when the sealing ring is locked about the mounting flange of the watthour meter and the rim of the socket adapter. In another embodiment, the terminal cover includes an outwardly extending filler portion which has an arcuate wall formed at an outer end. An annular flange and peripheral rim on the end of the arcuate wall forms a continuous extension of the annular flange and the rim on the side wall of the socket adapter housing. The terminal cover is locked in place on the socket adapter housing via the locking device used to lock the sealing ring about the socket adapter housing and the watthour meter.
