An electrical outlet has a female member with at least two electrically conductive contact sleeves for the reception of the pins on a plug inserted in the female member and a connecting means for connection of the electrical outlet to a mains supply. The female member is movable relative to the connecting means between a first mode, in which the contact sleeves are electrically disconnected from the mains supply, and a second mode, in which contact sleeves are electrically connected to a mains supply. The connecting means include a connection ring and a mounting plate. The connecting means further include connection plates, whose number corresponds to the number of contact sleeves on the female member, wherein each contact sleeve is brought in or out of contact with a connection plate by movement of the female member.

A shorting block includes a first shorting contact having a first contact portion, a second shorting contact having a second contact portion, the first contact portion and the second contact portion may electrically couple the first shorting contact and the second shorting contact in a shorting position of the shorting block, a first activation, and a second activation contact, the first activation contact and the second activation contact may be inserted into the first shorting contact and the second shorting contact, respectively, such that the first activation contact and the second activation contact direct the first contact portion and the second contact portion away from one another to form a gap between the first contact portion and the second contact portion in an operating position of the shorting block.

A shorting block includes a first shorting contact having a first contact portion, a second shorting contact having a second contact portion, the first contact portion and the second contact portion may electrically couple the first shorting contact and the second shorting contact in a shorting position of the shorting block, a first activation, and a second activation contact, the first activation contact and the second activation contact may be inserted into the first shorting contact and the second shorting contact, respectively, such that the first activation contact and the second activation contact direct the first contact portion and the second contact portion away from one another to form a gap between the first contact portion and the second contact portion in an operating position of the shorting block.

An electric meter socket includes: a first plurality of connection points within the electric meter socket configured to form electrical connections to line voltage wirings of an electric distribution system; a second plurality of connection points within the electric meter socket configured to form electrical connections to output voltage wirings of a DER device; one or more connection points within the electric meter socket configured to form an electrical connection of neutral wires of the electric distribution system, the DER device, and a load; and a plurality of receptacles, each of the plurality of receptacles electrically connected to a corresponding connection point and configured to accept a mating connector of an electric meter.

A method of securing an electrical terminal within a terminal cavity of a connector body is described herein. The method includes the step of deforming a portion of an outer surface of the connector body to fabricate a protrusion that projects from an inner surface of the connector body into the terminal cavity, thereby securing the electrical terminal within the terminal cavity. A connector assembly formed by this method is also described.

A feed-through terminal block module includes first and second electrical terminals, a first current bar, and a second current bar, the terminals and current bars in a terminal housing. The first current bar permanently electrically connects the first and second terminals. The first current bar includes a first contact portion of the module. The second current bar includes a second contact portion of the module and a third contact portion of the module. A removable contact plug is inserted into the housing to selectively electrically connect the first and second contact portions. Removable bridge pins or a bridging current bar electrically connects the third contact portions of adjacent modules when modules are placed side-by-side to form a terminal block.

A test system and method for relay connection and testing of a power transmission and distribution grid including a fixed connection block connected to the power transmission and distribution grid, and a mobile plug which connects the fixed connection block or a mobile test block with the relay when the mobile plug is inserted into the fixed connection block or the mobile test block. The mobile test block provides a connection to an external relay testing device when the mobile test plug is inserted into the mobile test block, the fixed connection block provides internal shorting that is activated when the mobile plug is not inserted into the fixed connection block and is deactivated when the mobile plug is inserted into the fixed connection block, and the fixed connection block, mobile plug, and the mobile test block provides an interaction between a power transmission and distribution grid side and a relay side. This allows a quick recovery when relays are damaged in a cyber-attack.

A connector device has a constitution in a connector in which a plurality of terminals protrude into a connector opening. The plurality of terminals are respectively provided with a plurality of switches that have independent states of supplying power to the terminals and are switchable in between. A plurality of conductor plates are provided in the connector opening in an attachable and detachable state, and are each configured to electrically connect at least two of the plurality of terminals. The plurality of conductor plates are coupled by an insulating member.

A distributor block includes: a supply input having an input terminal for connecting an electrical conductor; and a plurality of outputs, each output of the plurality of outputs having an output terminal for connecting an electrical conductor. The supply input is electrically conductively connected to a first current bar. Each output is electrically conductively connected to a second current bar. Between the first current bar and the second current bar, a fuse and/or a switch is arranged to connect the first current bar to the second current bar. A receptacle configured to hold the fuse and/or the switch is provided between the first current bar and the second current bar.
