Abstract
Residential fires of electrical origin have been a major concern for a long time. A fire can be initiated by excessive current (due to an overload or a short circuit), or arcing current. Therefore, both Canadian Electrical Code (CE Code) Part I and the National Electrical Code (NEC) require the installation of overcurrent protection devices (OCPDs) to detect and clear excessive current. Conversely, arcing current is too low for OCPDs to detect. It could take an electric arc, minutes, days, weeks, months, or even years to initiate a fire. Therefore, a new solution was required for detecting those slowly developing arcs. Thus, Arc-fault Circuit-Interrupters (AFCls) were born. AFCls are capable of detecting an arcing condition (while still developing) and de-energizing the circuit before the arcing circuit ignites. AFCls have been a hot topic creating quite a bit of controversy in the recent NEC review cycles. It is the authors' opinion that this controversy stems from a lack of clear understanding of AFCls operation, available technologies, and their capabilities. This paper is the first of two papers attempting to clarify the confusion surrounding AFCls, their applications, and success in making an impact on home electrical fires.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
