1.2 This Standard covers AFCIs that have a maximum rating of 20 A and are intended for use in 120-V ac, 60-HZ circuits. This Standard also covers cord AFCIs rated up to 30 A.
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.
