Abstract

Abstract A service disconnect adapter mounted between a plug-in meter socket and a watthour meter. The service disconnect adapter has blades mounted on a base which engage terminals in the socket. Watthour blade receiving fingers are formed in the service disconnect adapter to receive and frictionally engage watthour meter blades. The service disconnect adapter electrically isolates the socket load terminals from the watthour meter blades to disconnect the watthour meter from the load side terminals of the socket. The blades are angularly offset from the watthour meter blade receiving fingers in the adapter to mount the watthour meter at an angle from its normal mounting position. A pair of electrically conductive jumpers are mounted on and extend through the base in the adapter and are electrically connectible between the socket line terminals and the selected ones of the watthour meter contact blades to connect electric power to the watthour meter while the watthour meter load contact blades are disconnected from the socket load terminals.
