Scope

Main technical content: In recent years, the low-voltage complete equipment industry in Dalian City has developed rapidly. As of now, there are more than 100 low-voltage complete equipment manufacturing enterprises, which has injected strong impetus into the economic development of Dalian City. Due to the fact that the manufacturing of low-voltage complete equipment adopts national standards (GB7251 series standards) equivalent to the international IEC standards, the requirements for product quality are relatively high. At the same time, these products are included in the national mandatory product certification catalog, and the requirements for electrical safety quality are even higher. Therefore, quality control in the production process of enterprises is particularly important, especially the technical requirements for the installation and wiring process of complete equipment components are very high. However, at present, national standards, industry standards, and local standards do not propose specific requirements and regulations for the installation and wiring process of complete equipment components. Each enterprise formulates some internal control technical documents to regulate them, resulting in differences in the quality of complete equipment. In order to make the quality of high- and low-voltage complete equipment products in Dalian City safer and more reliable, and to make the production process of enterprises more standardized and formalized, the Dalian Electrical Quality Technology Association and Dalian Xincheng Electric Control Co., Ltd. took the lead in organizing several member units to study and formulate the "Installation and Wiring Process of Complete Equipment Components" group standard. The technical characteristics of this standard are formed through practice and in-depth research: (1) Scope of the standard: This standard specifies the equipment, tools, materials, process preparation, and process requirements for the installation and wiring
