XCFR2.GuideInfo Terminal Blocks - Component 端子台——部件 The devices covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN COMPLETE EQUIPMENT SUBMITTED TO UNDERWRITERS LABORATORIES INC. 含盖在这类别以下的设备是指某种结构特征上不完全的或在性能上受到限制的，并且作为完整设备其中的部件递交调查，而不是单独的装置可直接在一般市面上安装使用，这个部件最终可接受性是依据安装和使用在完整设备上后提交UL作判断。 GENERAL概述 This category covers assemblies of wiring terminals and supporting blocks intended to provide a means for the connection of wiring. These terminal blocks may employ terminal connectors, wire-binding screws, quick-connect terminals and similar friction fit terminals, which are intended for factory-wiring and/or field-wiring connections. 这类别包含接线端子的组装和提供电线连接方式的支撑座，这端子台可以使用端子连接器，螺钉绕线式，快速接线端子和相似功能的端子，可用于工厂组装和（/或）一般消费者自行组装。 Protective conductor terminal blocks (PCTB) are intended for connecting protective earthing (grounding) conductors to supports, such as mounting rails and the like. A PCTB is marked with the international symbol for ground, G,GR,GND,Ground,Grounding or the like. In addition, the insulation of a partially insulated PCTB is colored green or green/yellow. 保护性导体端子台（PCTB）是作为连接保护性接地导体用，例如固定架和相似装置。PCTB标有国际标示G,GR,GND,Ground,Grounding或类似标示，另外部分绝缘保护性导体端子台（PCTB）的绝缘是以绿色或绿黄色作标示。 USE用途 The following performance levels include ratings for voltage, current, wire size and type, torque (if applicable), suitability for factory wiring only or field wiring, and use group in order to facilitate investigation of their use in end-product applications. The following statements explain the tabular information: 以下性能标准包含电压、电流额定、电线尺寸和类型、扭矩（如果适用）、是只适合工厂接线或可以一般消费者接线、和为了在最终产品申请使用中方便调杳的使用范围，以下陈述是说明列表的信息。 Wire Range — The wire size or range of wire sizes for which a terminal blo
