This standard specifies the types, basic parameters and dimensions of three-phase plugs and sockets for household and similar purposes. This standard applies to three-phase plugs and three-phase fixed or mobile sockets used in household and similar household environments, with an AC frequency of 50Hz, a rated voltage of 440V, and a rated current not exceeding 32A.

GB1003--1999
In view of the fact that the types and sizes of three-phase plugs and sockets for household and similar purposes in various countries in the world have not yet been unified, and considering that the voltage and current levels of the three-phase plug and socket systems for household and similar purposes in my country need to be coordinated with GB2099.1-1996, the GB/T1003-1980 standard is revised.
This standard replaces GB/T1003-1980 "Types, basic parameters and dimensions of three-phase plugs and sockets" from the date of implementation. The differences between this standard and GB/T1003-1980 are: a. The rated voltage and rated current of the three-phase four-pole plugs and sockets specified in this standard have changed compared with GB/T1003-1980. This is mainly due to the consistency with GB2099.1-1996 "Part 1: General requirements for plugs and sockets for household and similar purposes". That is, the rated voltage is changed from the original 380V to 440V, and the rated current is changed from the original 15A to 16A, and the rated current is changed from 40A to 32A. b. According to the provisions of GB2099.1-1996 "Part 1: General Requirements for Plugs and Sockets for Household and Similar Purposes", the gauges of three-phase plugs and sockets are added.
This standard only stipulates the types, basic parameters and dimensions of three-phase plugs and sockets for household and similar purposes in my country. Its technical requirements and test methods should comply with GB2099.1-1996.
This standard is proposed by the Ministry of Machinery Industry.
This standard is under the jurisdiction of the National Technical Committee for Standardization of Electrical Accessories. The responsible drafting unit of this standard: Guangzhou Electrical Science Research Institute of the Ministry of Machinery Industry. The main drafters of this standard: Wang Yue, Jiang Yuanjing, Luo Huaiping, Sun Wanneng, Yang Guoxian, Yan Cuiqin. The verification units of this standard: Guangzhou Electrical Science Research Institute, Shanghai Jiaodian Home Appliances Business Association, Guangzhou Electrical Accessories Testing Station, Hangzhou Hongyan Electric Company, Nanjing Hongyan Electric Company, Hangzhou Hongshi Electric Company. The verification working group for this standard is: Sun Wanneng, Luo Huaiping, Yan Cuiqin, Yang Xiaohuai, Zhang Tinggang, Lu Chongheng. This standard was first issued in 1980 and revised for the first time in August 1999. 630

The terms and definitions in GB/T10964 and GB2099.1 apply to this standard. 4Technical requirements and test methods
The technical requirements and test methods for three-phase plugs and sockets for household and similar purposes shall comply with the provisions of GB2099.1. 5Types, basic parameters and dimensions
5.1The types, basic parameters and dimensions of three-phase plugs and sockets for household and similar purposes shall comply with the provisions of Figure 1, Figure 2 and Table 1 and Table 2. To check these dimensions, special gauges and vernier calipers with a graduation value of 0.02 mm as specified in Figures 3 to 6 and Tables 3 to 6 shall be used. The roughness of these gauges is all √, the hardness is HRC58 to 62, and the shape and position tolerances of the gauges such as parallelism, verticality and symmetry shall be in accordance with the tolerance level 7 specified in GB/T1184.
5.2 The shape of the plug is not specified. However, the distance between the plug pin and the edge shall ensure that it meets the requirements for protection against electric shock. Approved by the State Administration of Quality and Technical Supervision on August 2, 1999, the product was reduced in size. Implementation from October 1, 2000 to October 1.
