摘要： The system includes one or more busbars couple to an AC line, branch relays each coupled to a busbar and to a respective circuit breaker, and current sensors each corresponding to at least one respective branch relay of the plurality of branch relays. The system also includes a deadfront arranged in front of the plurality of branch relays, and including openings corresponding to the branch relays allowing an electrical terminal of each branch relay to protrude forward through a respective opening. A circuit breaker is engaged with each respective branch relay, on the deadfront to create an array of branch circuit breakers. The combination of relay and circuit breaker allows each branch circuit to be controllable. The relays may include current sensors, such as a shunt, used to determine a branch circuit current and control the relay. Control circuitry manages the relay on-off operation and monitors branch circuit operation.

摘要： An electronic protection system is implemented in an electrical panel that distributes electricity to branch circuits at a site. The electronic protection system includes a current sensor, an actuator and a processor. The current sensor senses a current flow through a branch circuit. The actuator can be used to de-energize the branch circuit. The processor controls the actuator based on the current flow sensed by the current sensor, according to a trip-time curve implemented by the processor. The trip-time curve specifies a maximum duration of current flow for different amounts of current flow.

摘要： A system includes control circuitry for identifying, during operation in a first operating mode wherein electrical power is limited by protection devices, an indicator to enter a second operating mode. The indicator corresponds to power consumption of the electrical system exceeding a power capacity of the electrical system, nearing, achieving, or exceeding a limit. In response to the indicator, the system operates in the second operating mode by retrieving reference information comprising load preferences and limits, and managing one or more loads, sources, or both to modify power consumption, power capacity, or both based on the indicator and based on the reference information. The system communicates with loads or sources, and manages branch circuit using controllable elements to prevent power consumption from exceeding power capacity. The system modifies setpoints, turns devices on or off, schedules device operation or otherwise manages the electrical system based on predetermined preferences.

摘要： A system for managing electrical loads includes a plurality of branch circuits, a sensor system, and control circuitry. The sensor system is configured to measure one or more electrical parameters corresponding to the plurality of branch circuits, and transmit one or more signals to the control circuitry. The control circuitry is configured to determine respective electrical load information in each branch circuit based on the sensor system, and control the electrical load in each branch circuit using controllable elements based on the respective electrical load information. The control circuitry transmits usage information, generates displays indicative of usage information, accesses stored or referencing information to forecast electrical load, and manages electrical load in response to identified events. The control circuitry can associate each branch circuit with reference load information, and disaggregate loads on each branch circuit based on the reference load information and on the electrical load in the branch circuit.

摘要： Aspects of this disclosure concern the integration of AFCI protection into the electrical panel itself. An electrical panelboard includes a main terminal that receives a supply of electricity, multiple terminals to supply electricity to branch circuits, and a bus structure that distributes the electricity from the main terminal to the branch circuit terminals. The branch circuit terminals may be conductive stabs, to which traditional overcurrent circuit breakers are attached. The AFCI protection is integrated, either fully or partially, onto the panelboard, rather than implemented as separate stand-alone devices. The integrated AFCI protection includes current sensors, switching devices and a processing system. The current sensors sense the flow of electricity through the branch circuits and the switching devices can interrupt this flow of electricity. The processing system analyzes the detected currents for arc faults and controls the switching devices accordingly.

摘要： A portion of an electrical panelboard may include an arc fault circuit interruption (AFCI) protection system configured to detect arc fault events occurring in branch circuits and interrupt the flow of electricity in one or more of the branch circuits, where interruption switching devices of the AFCI protection system are electrically coupled between (a) one or more bus bars of the electrical panelboard and (b) branch circuit terminals of the electrical panelboard. The portion of the panelboard may also include an interface panel that enables a user to interact with the AFCI protection system.
