1. A circuit interrupter comprising:
a housing configured to be installed in at least one of an electrical wall box or a load center;
a conductive path;
a switch configured to selectively interrupt the conductive path;
a sensor in electrical communication with the conductive path and configured to measure an electrical characteristic of the conductive path, the sensor configured to provide a plurality of sensor measurements;
a memory having an arc detection program stored therein, the arc detection program implementing a machine learning model, the arc detection program including a field-updatable program portion configured to be field-updatable and a non-field-updatable program portion, the field-updatable program portion including a plurality of machine learning model parameters, wherein the non-field-updatable program portion is configured to use the plurality of machine learning model parameters to decide between presence of an arc event or absence of an arc event; and
a controller positioned within the housing and coupled to the memory, wherein the arc detection program, when executed by the controller, causes the controller to perform an operation comprising:
computing input data for the machine learning model based on the plurality of sensor measurements,
providing a decision between presence of an arc event or absence of an arc event, the decision based on the input data, and
causing the switch to interrupt the conductive path when the decision indicates presence of an arc event.
