    Hi

    I've just bought a Neodigits X3000 network media player.
    http://www.neodigits.com/new/body/products/Xline/x3000.asp
    When I was mucking around connecting it up I got a shock from the case. To cut a long story short, the metal case is unearthed and floating at 110v! I contacted the company I bought it from and they tested another which is exactly the same.
    I sent of an e-mail to Neodigits to ask what was going on, and got a one liner back which said "this is correct" and " this product has been CE and FCC certified".

    Is there something in the CE certification process that I don't know about?

    Am I being really stupid here?

    All opinions gratefully received.

    it could just be static building up a charge.

    Surely it cannot be static if the chap has measured 110v..the multimeter or whatever would have dumped the static..The case is reading 110v..something is seriously amiss here (poss ****** fault/bad design) and is not a normal state of affairs..as a rough guess would think the PD on the case is induced..the manufacturer must be approached on this subject as it could turn nasty.

    OK.Maybe I should have put it like this....

    I have an UNEARTHED metal case with LIVE 240v conductors inside, which happens to be called an X3000

    I'ts been a while, but I'm sure the regs used to say that "any exposed metal that could potentialy become live under fault conditions must be earthed".
    Is this still the case?... then if so , how did the X3000 become CE approved?

    how did the X3000 become CE approved?

    Maybe the X3000 submitted for approval did indeed comply... but maybe after approval the makers decided to cut costs.

    Maybe.

    If its a class 1 product then it should be earthed.

    However....

    Is the X3000 connected to a socket thats earthed ??????

    don't they have a seperate ground lead to avoid static build up anyway

    Does it have the double insulated symbol on the back? If so it may be a production fault, something not insulated correctly coming into contact with the case. Only a thought as not all metal cases are earthed if the product is double insulated.

    The product has a 110/240v switching power supply built in... and the piccys show it as having a 3 pin connector

    Sorry didnt look at the picture, maybe I should have.

    Naahhhh.. its not a wonderfull piccy

    Maybe the shock warning sticker on the back should be changed to dangerous voltages present without having to open. Did you honestly get a shock off it and if so then give it another go just to make sure!

    Personally I think that Neodigits are at it.

    The X3000 isn't Double insulated and yes I did get a shock of it .....Twice

    Is there continuinty between the earth pin and the case ...

    If not.. open the case and see whats connected to the earth pin

    Neodigits say Having the case at 110V is correct!!!


    Unbeleivable ,there must be some mistake .

    There is no continuity between the case and earth.

    I agree with JP and think that the voltage on the case is induced. The current involved is negligible, but still enough to give you a tingle.

    I think I'll have a word with trading standards

    Just a quick question..

    Although the pic of the unit shows a three pin power input..which obviously implies that there is an earth line..(Thinking this unit is suitable for the States etc and would think at 110v it would be plugged into a two pin receptacle non grounded outlet) if you take the plug off is there in fact an earth wire?..ie is there just an earth and neutral? no earth.

    2..When you measured the 110v floater was there any other item of equipment plugged into the inputs/outputs of the unit?..by this I mean anything..signal lines etc etc..
