Resistance to tracking

Tracking is a phenomenon in which dust or moisture adheres between electrically insulated conductors, causing a short circuit and leading to fire or insulation breakdown due to a large short-circuit current. A common example is a short caused by dust accumulated in an outlet, which can lead to an electrical fire. This refers to the resistance against such tracking. To improve tracking resistance, methods include designing structures that prevent dust accumulation, using materials that are less prone to static electricity, or adopting waterproof designs.
