Connecting devices for low-voltage circuits for household and similar purposes - Part 2-1: Particular requirements for connecting devices as separate entities with screw-type clamping units
用于家用和类似用途的低压电路的连接装置 - 第2-1部分:用螺钉式夹紧装置将设备作为独立实体连接的特殊要求
This standard applies to connecting devices with screw-type clamping units primarily suitable for connecting unprepared conductors.
This Part 2-1 is intended to be used in conjunction with IEC 60998-1. It was established on the basis of the second edition (2002) of that standard.
This second edition cancels and replaces the first edition published in 1990 and constitutes a technical revision.
