APPARATUS FOR GROUNDING EXTERNAL METAL WATTHOUR METER COMPONENT

摘要

A watthour meter socket adapter electrically connects an external sealing ring and/or a metal cover ring on a watthour meter to ground. A surge ground conductor is mounted on an end mounting flange of the socket adapter housing and extends within and is joined to the housing by a first metal fastener. One end of the first metal fastener extends exteriorly of the housing and supports a first metal tab which is engaged by the metal sealing ring. A second metal fastener extends through the surge ground conductor and supports a second external tab engagable with a grounded meter socket cover. Alternately, a tab extends integrally from an upper end of the surge ground conductor for engagement with the sealing ring. In another embodiment, an annular surge ground conductor is mounted within an annular sidewall of a watthour meter socket adapter housing. A flange extends from one end of the surge ground conductor through a slot in a terminal cover into proximity with a sealing ring mountable about a mounting flange on the housing and a mating mounting flange carrying a metal cover ring on a watthour meter. A wire seal is passable through the flange and the sealing ring to electrically connect the metal cover ring on the watthour meter, the sealing ring and the flange on the surge ground conductor to a groundconnection.
