Abstract: 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.

Abstract: 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.
