      Welcome

      Over in Paris do they have 120 Volt 60 Hertz power around, or is it mostly just 200 Volts and 50 Hertz? I'm thinking for residential service.

        Woussko;

        Unforetealy we still have very few 120v 50 hz service left majorty are 215/400 volts 50 Hz but majorty of the home used the single phase unless have large electric stove or large water heater storage tank type it can bring in 400 volts and the colour code is diffrent what you see in North America system is

        Brown = hot
        Red = hot
        Grey = hot [* i am not sure if that is corret colour they change a bit over the years ]

        Green or Green with yellow stripes = ground aka earth

        Bleu = netural


        for home main service they used any where from 40 to 100 amp depending on size and load .
        [ for larger size it coustmary to bring in 3 phase in anyway ]

        Merci , Marc

          Thanks for the info.

          Over here in the USA (I'm sure you already know this) the colors are as follows.

          Single Phase:
          Line 1: Black
          Line 2: Red
          Neutral: White
          Ground: Green
          Ground can also be bare copper when not in a conduit

          In a 3 phase system
          Line 1: Black
          Line 2: Red
          Line 3: Blue
          Neutral: White
          Ground: Green

          Something I see way to much of is that the conduit is used as ground. If it ever came apart at a joint (happens) then the grounding is lost. I think the code needs to read that in all cases there must be a green ground conductor.
