Abstract:
A system includes a meter socket adapter (MSA) to electrically connect a meter socket and a utility meter, electrical contacts to electrically connect the MSA to the meter socket and the utility meter, and a data circuit to measure an electrical load through the MSA, and a pluggable assembly coupled to the MSA, the pluggable assembly including a housing to be coupled to the MSA housing, at least one of a set of power interface connectors extending from the housing into the MSA housing to connect to the MSA electrical contacts and a data interface connector extending from the housing to removably connect to the MSA data circuit, and at least one of an electrical circuit interface to electrically connect the set of power interface connectors to the electrical circuit and a data circuit interface to electrically connect the data interface connector to the data circuit.
Abstract:
A meter socket adapter may include an integrated whole-building disconnect switch configured to disconnect a building associated with the meter socket adapter from a utility grid, a distributed energy resource (DER) interface to connect a distributed energy resource (DER), and an energy management system (EMS) configured to monitor electrical current passing through the meter socket adapter and, based on the monitored current, actuate the whole-building disconnect switch.

Abstract:
An interface to an electric vehicle or comparable energy storage system, paired with a utility electric power meter or meter collar adaptor with embedded control and whole-site disconnect switch that, when operated together, enables the user to: isolate the site from the grid during a power outage and use the vehicle or energy storage system to provide power to the site; manually reclose the disconnect switch to the grid only when safe operating conditions are met; allow a remote grid-operator to manage charging of the vehicle; and prevent the utility service from being overloaded when proving power to the residence and the meter adaptor loads simultaneously.
Abstract:
Technologies are generally described for a pocket junction box system. In an example, a pocket junction box is configured to fit inside a meter collar. The pocket junction box includes a first set of electrical terminals on a rear surface of the pocket junction box for interfacing with wire leads inside the meter collar, and a second set of electrical terminals on a front surface of the pocket junction box for interfacing with field wire leads outside the meter collar. The pocket junction box may further include at least one current transducer and at least one microprocessor for monitoring the power flow through the pocket junction box. A front casing is attached to the front surface of the pocket junction box and connected to the second set of electrical terminals. The front casing may include a communications circuit board for communicating with a meter data management system.
Abstract:
A watt-hour meter may include one or more electrical junction points that interface a Distributed Energy Resource to an energy-consuming structure and to the electrical distribution grid, while maintaining compliance with interconnection requirements for safety, power quality and automatic disconnect capabilities

Abstract:
Technologies are generally described for a socket, plug, and jumper system. In an example, a receptacle socket includes a first prong receptacle for a ground circuit, a second prong receptacle for a neutral circuit, and a third prong receptacle for an active voltage circuit. A plug housing includes a first prong contact corresponding to the first prong receptacle for the ground circuit, a second prong contact corresponding to the second prong receptacle for the neutral circuit, and a fourth prong receptacle for the active voltage circuit. A jumper component includes a third prong contact corresponding to the third prong receptacle for the active voltage circuit, and a fourth prong contact corresponding to the fourth prong receptacle for the active voltage circuit, wherein the fourth prong contact is completely recessed within the jumper component.
