Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equipment input current ≤16 A per phase)

This document establishes the maximum permissible limits for harmonic currents in single-phase electrical supply systems with input currents of 16 amperes or less. It specifies the boundary values that electrical and electronic equipment must not exceed to ensure the power quality of the grid remains unaffected by harmonic distortion generated by connected devices. The scope covers various types of electrical apparatus, defining specific criteria based on the current ratings and operational characteristics of the equipment. Compliance with these technical requirements is essential for manufacturers and importers to ensure their products are suitable for use within the relevant regulatory framework. The text details measurement procedures and test conditions necessary to verify adherence to the defined limits. These provisions are aligned with international technical standards, facilitating trade and interoperability across different markets. By setting clear thresholds, the regulation helps mitigate electromagnetic interference and supports the stability of electrical distribution networks for all connected users.
