Abstract
A socket adapter housing has a plurality of line and load blade terminals and jaw contacts. An electrical power disconnect device, mounted in the housing, has contacts switchable between closed and open states, the contacts being serially connected between the line blade terminals and the line jaw contacts. Rigid bus bars are fixedly connected to terminals on the power disconnect device extending from the switchable contacts and to the line blade and line jaws to fixedly mount the power disconnect device in the socket adapter housing. Surge suppression devices are connected between the load blade terminals and ground potential. An insulating safety shield is mounted in the housing and completely surrounds the line and load jaw contacts. Alternately, the housing includes a watthour meter receiving portion containing the power disconnect means and the line and load blade terminals and jaw contacts. An auxiliary housing is affixed along with the watthour meter receiving housing to a common base and contains the surge suppression devices. A cover is removably mountable on the auxiliary housing.
