I'm completely frustrated by the re-classification of voltage ratings
in the EU. XLR plugs previously rated for hundreds of volts in
manufacturers instructions are now down-rated to 50v for "domestic
applications". Now I see amphenol AP and EP series are quoted, for the
4 pin, as service voltage 660v, but 50v for "domestic applications".
So is it legal to sell equipment where a 4 pin AP plug carries over
50v but under the service voltage of 660v? Thinking of umbilicals for
valve equipment

If they're to be used domestically, it would seem not. Or can you
read any other meaning into the new ratings?
