GB/T 16895.3-2024 Low-voltage electrical installations—Part 5-54:Selection and erection of electrical equipment—Earthing arrangements and protective conductors
Abstract
This document sets forth corresponding provisions for grounding configurations and protective conductors, in order to meet the safety requirements of electrical installations.
This document also includes grounding and equipotential requirements for information and communication technologies (ICT), with the aim of:
——Reducing the risk of electrical hazards during the normal operation of these devices and ICT lines;
——Providing a reliable signal reference standard for telecommunications systems, in accordance with ISO/IEC 30129, to enhance their resistance to electromagnetic interference (EMI).
Note: Examples of information and communication technologies (ICT) include:
——DC power supply networks (and systems) for ICT equipment in buildings;
——Star-type private automatic branch exchanges (PABX) and their equipment;
——Local area networks (LANs);
——Fire and intrusion alarm communication systems;
——Building automation systems, such as direct digital control systems;
——Computer-aided manufacturing (CAM) and other computer-aided service systems;
——Broadcasting and communication technologies.
