All regular electrical devices without special circuits generate harmonic currents into
distribution network. High rates of harmonic current may cause losses and disturbance to
some equipment. This equipment complies with IEC 61000-3-12 provided that the short-
circuit power Ssc is greater than or equal to 7.6 MVA at the interface point between the user's
supply and the public supply network. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution network operator if necessary, that
the equipment is connected only to a supply with a short-circuit power Ssc greater than or
equal to 7.6 MVA.
