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
