Definition and decision context

Definition

Arc-fault detection evaluates electrical signals consistent with arcing against electrical noise for interruption decisions.

Why it matters

Topology and noise attenuation can affect detection, so an indication does not establish an arc's cause or location or supply a reset instruction.
