EN 61000-3-3 on limitation of flicker is enforced in Europe as part of the EMC Directive. (Flicker is the name given to the phenomenon of short term mains supply voltage variations, which cause third-party lights to flicker, when a particular piece of equipment presents a substantially varying load to the mains.) EN 61000-3-3 applies limits to the values of voltage variation which may be impressed on the supply, assuming a defined supply impedance.
Question: is there any US jurisdiction which applies these limits e.g. via the international equivalent IEC 61000-3-3, or indeed any other standard? Individual states or nationwide?
