Scope

Scope: This standard specifies the technical requirements for the installation of low-voltage switchgear. This standard applies to general low-voltage switchgear with an AC rated voltage of 1200V and below, or a DC rated voltage of 1500V and below, installed and adjusted under normal conditions for testing, including low-voltage circuit breakers, low-voltage switches, contactors, starters, controllers, buttons, fuses, etc. Main technical content: To standardize the technical requirements for the installation of low-voltage switchgear, the standard stipulates the installation of low-voltage switchgear through pre-installation inspections, requirements for installation height and distance, fasteners, external electrical wiring, installation of low-voltage circuit breakers, low-voltage switches, contactors, starters and controllers, button installation, fuse installation, grounding requirements, installation environment, and post-installation debugging and acceptance inspections. Maintenance and maintenance are also stipulated to improve the installation standards of low-voltage switchgear and promote the sustainable development of the automation industry. This standard is therefore formulated.
