根据出版者的命令，历史UL文件不可出于任何原因退回。一旦您订购历史文件，我们将无法退款、贷记或进行任何形式的交换。1.1本标准的要求包括分支/馈线的电弧故障电路断路器（AFCI）、插座电路、便携式电源和用于 住宅单元。这些装置旨在减轻电弧故障的影响，如果电弧持续存在，在某些情况下可能会造成着火风险。 1.2这些设备的最大额定值为20 a，拟用于120-V ac、60-HZ电路。1.3这些设备不用于检测发光连接。1.4在这些要求中，设备一词一般用于适用于这些要求所涵盖的所有设备，并在要求不适用时进行修改 不适用于所有类型。1.5还用于执行其他功能的AFCI，如过电流保护、接地故障电路中断、浪涌抑制或任何其他类似功能 功能或其任何组合还应符合适用标准的要求，这些标准涵盖了提供这些功能的设备 功能。1.6包含新特性、特性、组件、材料或系统的产品，或与本标准要求所涵盖的特性、特性、组件、材料或系统不同的产品，以及 涉及火灾、触电或人身伤害风险的，应使用适当的附加组件和最终产品要求进行评估，以 保持本标准意图最初预期的安全水平。特性、特性、组件、材料或系统发生冲突的产品 本标准的具体要求或规定不符合本标准。 要求的修订应以一致的方式提出和采用 制定、修订和实施本标准所采用的方法。

By order of the publisher, historical UL documents are not returnable for any reason. Once you place an order for an historical document, we cannot issue a refund, credit, or exchange of any kind.1.1 The requirements of this Standard cover arc-fault circuit-interrupters (AFCIs) of the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.1.2 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.
