UL 1699
http://ulstandardsinfonet.ul.com/scopes/1699.html 1 Scope
1.1 The requirements of this Standard cover arc-fault circuit-interrupters (AFCIs) of the branch/feeder, outlet circuit, portable, and cord 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.
1.1.1 The requirements of this Standard also cover Leakage-Current Detector-Interrupters (LCDIs), which are not prohibited from being provided with cord sets or power-supply cords. These devices are intended to sense leakage currents flowing between or from the conductors of a cord set and interrupt the circuit at a predetermined level of leakage current.
1.1.1 added effective July 15, 2004
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.
