Carl,
Your response is as good of answer as I have seen on this topic. I live in the country and my house is powered by its own transformer to I guess I live in an industrial environment. Haha. Neil, Are you in fear of your product failing the harmonic & flicker test requirements or do you just want to avoid the cost and trouble of having it tested? Based on your product design and how it draws power from the mains can you justify not having your product tested? For many products, I think you can easily use the TCF approach to justify not testing. However, if there is any doubt, get it tested. Then you will know. It is not an expensive test to have done.

That would depend on how and what the equipment in which the panel-mount device is installed is connected to. Anything pluggable could be expected to be connected to a public low voltage distribution system. Also, you could, for example, have a panel-mount device installed in a rack of equipment that in itself is connected to the 'public low voltage distribution system' or 'mains'. However, if that rack of equipment is installed on an industrial site with its own power substation and never likely to be otherwise, then it would indeed be exempt. Equipment on industrial sites is generally subject to the regulations of the supply authority who do not want you to consume lots of reactive power that you are not paying for. Sorry, not a straight answer. The status depends not so much on the nature of the equipment as the type of installation in which it is likely to be used.

I see within the Scope of EN 61000-3-2 and -3 that those standards should apply to devices which are connected to 'public low-voltage distribution systems'. Are panel-mount type devices intended for use in industrial applications generally exempt from those standards due to this clause?
