GB/T 14048.7-2006 in English

《GB/T 14048.7-2006低压开关设备和控制设备 第7-1部分：辅助器件 铜导体的接线端子排》由TC189（全国低压电器标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准规定了主要用于工业或类似用途的安装在支架上为铜导线提供电气连接以及机械连接的螺纹型或非螺纹型接线端子排的要求。
本标准适用于额定电压交流不超过1000V1) 、频率至1000Hz或直流不超过1500V电路中，用于连接截面积为0.2mm～300mm(AWG24/600kcmil)经过或未经过特殊加工的圆铜导线的接线端子排。

Scope

This standard specifies the requirements for screw-type or non-screw-type terminal blocks mounted on racks to provide electrical and mechanical connections for copper conductors, mainly for industrial or similar purposes. This part is applicable to circuits with a rated voltage AC not exceeding 1000V¹⁾, a frequency up to 1000Hz or a DC not exceeding 1500V, for connecting cross-sectional areas of 0.2mm² to 300mm² (AWG 24/600 kcmil) with or without specially processed round copper wire terminals in rows. The following products may use this standard as a guide: - Terminal blocks that require special devices on the conductors, such as quick-connect terminals or wrap-around connections, etc.; - special type of terminal block, such as isolation terminal block, etc. When referring to GB 14048.1, the term "clamping piece" is used in this section instead of "terminal".
