Abstract: An electronic overload current breaker supports arc-fault and ground-fault (AFGF) detection along with built-in shunt calibration (BISC™). The breaker may include a current sensing shunt and a control circuit electrically coupled to the current sensing shunt. This control circuit is configured to calibrate the current sensing shunt in response to application of a calibration current to the breaker. The control circuit can: (i) determine a magnitude of the calibration current applied to the breaker, (ii) map the magnitude of the calibration current to a first one of a plurality of current ratings for the breaker, and (iii) set the breaker to monitor overload conditions at the first one of the plurality of current ratings. The plurality of current ratings for the breaker can be less than the magnitude of the calibration current.

Abstract: In an example embodiment, systems and methods are described for demand prediction and profitability modeling based on heterogeneous data and blended clustering models. Data for a plurality of items is received and differentiated into a first set of good items and a second set of bad items. Good items and bad items may be indicated by a threshold for a prediction accuracy metric, such as weighted Mean Average Percentage Error (MAPE). A first model for predicted demand levels of the good items is generated that excludes cross-cluster effects with the bad items. A second model of the bad items is generated that includes a residual correction and cross-cluster effects with the good items. A predicted demand of a particular item is generated based on a cluster-level regression model and at least one of the first model and the second model.
