BS EN 61000-3-2:2006 + A2:2009 Electromagnetic compatibility (EMC). Limits. Limits for harmonic current emissions (equipment input current $3L 16 A per phase)
BS EN 61000-3-2 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions.
BS EN 61000-3-2 applies to electrical and electronic equipment with an input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems.
Arc welding equipment which is not professional equipment, with input current up to and including 16 A per phase, is included in this standard. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this standard and may be subject to installation restrictions as indicated in IEC 61000-3-4 or IEC 61000-3-12.
The tests according to this standard are type tests. Test conditions for particular equipment are given in Annex C. For systems with nominal voltages less than 220 V (line-to-neutral), the limits have not yet been considered.
