A housing carries an electrical disconnect switch having movable contacts. A cover is mounted on the housing and has an opening allowing access to a control lever of the disconnect switch. Electrical conductors are connected to the disconnect switch within the housing and have a blade terminal portion extending exteriorly of the housing for connection to jaws carried on an electrical component mountable in an electrical watthour meter socket. Degassing ports are formed between the cover and the sidewall of the housing to allow any arcing gasses generated within the interior of the housing to escape from the housing. A handle is mounted centrally on the cover. An ejector handle is movably mounted on the cover and carries an ejector arm to separate the housing from an attached electrical component. A method of removing and remounting a watthour meter in a meter socket is provided, including sequence steps printed on the face of the housing.
