Arc tracking

Arc tracking is a phenomenon in which a conductive carbon path is formed across an insulating surface. The carbon path provides a short circuit path through which current can flow (e.g., electrical arcing.) Circuit breakers are especially susceptible to Arc Tracking.  The effects of electrical faults can include: • Component overheating • Toxic fumes • [...]
