Description / Abstract: These requirements cover arc-fault circuit-interrupters (AFCIs) of the outlet branch circuit type intended for use in dwelling units. These devices are intended to mitigate the effects of arcing faults that may pose a risk of fire ignition under certain conditions if the arcing persists.

These devices have a maximum rating of 20 A and are intended for use in 120-V ac, 60-HZ circuits.

These requirements are intended to be used with the Standard for Arc-Fault Circuit-Interrupters, UL 1699, as these requirements modify the requirements described in that standard.

Unless otherwise specified, when the term "arc-fault circuit-interrupter" or "AFCI" is used in this Outline, it refers to an arc-fault circuit-interrupter of the outlet branch circuit type, also known as an outlet branch circuit arc-fault circuit-interrupter (OBC AFCI).
