This part of IEC 61000 deals with the limitation of harmonic currents injected into the public supply system.
It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions.
This part of IEC 61000 is applicable to electrical and electronic equipment having a rated 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 a rated input current up to and including 16 A per phase, is included in this document. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this document and can be
subject to installation restrictions as indicated in IEC 61000-3-12.
The tests according to this document are type tests.
For systems with nominal voltages less than but not equal to 220 V (line-to-neutral), the limits have not yet been considered.
NOTE The words apparatus, appliance, device and equipment are used throughout this document. They have the same meaning for the purposes of this document.
