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.
1.2 These devices have a maximum rating of 20 A and are intended for use in 120-V ac, 60-HZ circuits.
1.3 These devices are not intended to detect glowing connections.
1.4 In these requirements the term device is used generically to apply to all of the devices covered by these requirements and is modified when the requirement does
not apply to all types.
1.5 An AFCI that is also intended to perform other functions, such as overcurrent protection, ground-fault circuit-interruption, surge suppression, any other similar
functions, or any combination thereof, shall comply additionally with the requirements of the applicable Standard or Standards that cover devices that provide those
functions.
1.6 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and
that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to
maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict
with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance
with the methods employed for development, revision, and implementation of this standard.
