    Sounds like what is called a Shukko (spelling?).

    Looking at the socket, with the earth pin at the top, live is on the
    right, neutral on the left.

    The earth pin is in the socket. The live and neutral pins are on the
    plug. Is that what you have there?

    So countries where your kludge most likely will not work would be the UK
    and Ireland (they got some really weird monster plugs), Denmark, Italy
    and Switzerland.

    As for polarity I don't know, I lived mostly in countries with the
    external contacts so no polarity there.

    And don't forget to turn stuff to 230V. I once did with a razor. Phssst
    .... BANG.
     
  3. I just picked up a Euro style plug (continental) at the local parts
    shoppe. Its a two round prong plus side grounding contacts at top and
    bottom. Upon closer inspection, it also appears to have a socket at the
    12 o'clock position that will accept a mating (round) ground pin in a
    receptacle so equipped.

    I've seen two hole receptacles. I've also seen the ones with the recess
    and the side ground contact. Where to they hace a recepacle with two
    holes (at 3 and 9 o'clock) for hot and neutral and a pin at 12 for
    ground? Since there is only one pin, this could suggest that the
    plug/receptacle may be polarized. If so, which side of the receptacle
    (looking into the receptacle) would be neutral and which hot? In
    countries that use the side grounding contacts, I understand that there
    is no defined polarization. Correct?

    The brand name on the plug is Legrand.

    I may burn in hell for this, but I'm goint over to that side of the pond
    and I'm making my own adapter from a USA 3-way extension cord head and
    this plug.

    You'll find the English language version here:

    It's Schuko, short form for Schutzkontakt (protection contact).

    In Germany and other countries there isn't much of a convention which
    side is hot because you can plug them in either way.

    Bear in mind that there is not really any such thing as a Euro plug. The one you
    have (probably a Schuko type E/F hybrid ) is a compromise that will work in many
    instances, especially in Germany and France, though.

    You need to check what it is you'll be plugging into wherever it is you're
    going.

    Some European countries do not have earthed sockets widely available either AIUI
    (Denmark ? for example perhaps).

    I suggest you read.....

    Am I missing something - aren't both sides hot? In the US, the only way you
    can tell the diffference in a 240V plug between the red and black wires
    would require a clock that is accurate to better than 4 milliseconds
    absolute.

    In Europe, domestic, office and very light industrial power is distributed as
    230V single phase with the neutral conductor potential close to ground. There is
    no centre tapped 240V as you have.

  9. Yes.
     
  10. Germany must use the recessed socket with a side ground contact, so the
    plug (with top and bottom side contacts) can be flipped and hot and
    neutral are reversible. Wherever they use the 'Schuko' (as described
    above), I don't think the plug could be reversed. If the neutral is at 9
    o'clock, hot is at 3 o'clock and ground is a pin at 12, the plug would
    not be capable of reversal.
     
  11. From this description, the Schuko is the reversible plug/socket with
    side ground contacts and must be non-polarized. What I have is a hybrid
    Schuko/French plug (bottom photo).
     
  12. I have a multi-way (British, Continental, US, Australian) input/output
    plug adapter. But it only handles one plug, so I'm making a short
    extension cord with a triple receptacle head to accomodate my entire
    menagerie of gizmos.
    Everything I have has a SMPS with a 100-240V range, no switching
    required.
     
  13. This is the Schuko (Schutzkontakt, = protection (ground) contact).
    Of course it can. It can't be reversed with the outlets that have the ground
    sticking out at 12 o'clock (possibly French), but those aren't called
    Schuko. Virtually all modern Schuko plugs have that extra receptacle,
    though, because it's compatible with the Schuko geometry.

  14. Well, eh, in old Amsterdam, you know, it once was 2 phases (both live) with 220V beteen these.
    I found out the hard way....
    It would not surpize me if still some old parts of the city were like that.
    Do not assume.

    Hint: Legrand is (or used to be) a French company.

    In France, the wall mounted plugs have two holes for live and neutral
    and a prong for earth.
    As to which side is neutral and which is hot, well, there must be a
    "standard" somewhere but NEVER trust it. All devices here are designed
    to cope with wichever way the wall mounted plug is wired.

    I see from the link above that the plug is rated at 16A. I don't think
    I would stand too close when it is carrying that much current. Give me
    a CeeForm 16A plug any day.

    Hey, it's got bigger pins than a US plug.

    I believe since the early 90's everything new is made with earth.
    Our plugs look like the french but with three prongs, so a schuco plug
    will fit a danish socket but won't get earthed.
    A danish plug with earth won't fit in a socket without earth (unless
    you saw off the extra prong which I'm sure happens alot )
