IEC TS 61000-3-4
IEC TS 61000-3-4 Electromagnetic Compatibility (EMC) - Part 3-4: Limits - Limitation of Emission of Harmonic Currents in Low-Voltage Power Supply Systems for Equipment with Rated Current Greater Than 16 A This standard is applicable to electrical and electronic equipment with a rated input current exceeding 16 A per phase and intended to be connected to public low-voltage AC distribution systems of the following types: - nominal voltage up to 240 V, single-phase, two or three wires; - nominal voltage up to 600 V, three-phase, three or four wires; - nominal frequency 50 Hz or 60 Hz. These recommendations specify the information required to enable a supply authority to assess equipment regarding harmonic disturbance and to decide whether or not the equipment is acceptable for connection with regard to the harmonic distortion aspect.
