Scope

This part of GB 7251 specifies the definition, service conditions, structural requirements, technical characteristics and verification requirements of the following low-voltage complete equipment (see 3.101): --The complete set with a rated voltage not exceeding 1 000 V for AC and 1 500 V for DC Equipment; --Complete equipment used in conjunction with equipment for power generation, transmission, distribution, power conversion and control of power consumption; Provided that the relevant specific requirements are complied with; --- Assemblies designed for the electrical equipment of machines, IEC 60204 contains supplementary requirements for assemblies forming part of machines. This section applies to all one-off design, manufacture and inspection or fully standardized mass-manufactured complete sets of equipment. Production and/or assembly may not be performed by the original manufacturer (see Part 1, 3.10.1 and 3.10.2). This section does not apply to individual devices and self-contained assemblies such as motor starters, knife fuse switches, electronic equipment, etc. that meet their respective product standards. This part does not apply to specific types of complete equipment in other parts of GB 7251, power rail systems in GB 13961-2008, cable trays and duct systems in GB/T 19215 (all parts) and in IEC 61534 (all parts) power track system.
