    Yep that is why i was posting that grounded ground grounding cannot be used interchangably because they do not mean the same thing. Another issue I see frequently is people not understanding the difference between grounding and bonding. The second image you posted there causes even more confusion, I have always known the earth ground symbol to represent ground but recently i have seen articles and even some schematic software using the commom ground symbol to represent ground calling the earth ground something different entirely.

    You will see items sold here such as BOB's etc and/or a schematic posted and they all use the earth ground symbol as a power Common, regardless if it is non-earthed.
    The book highly praised by many, The Art Of Electronics commit the offense all the way through.
    The earth ground symbol I show was established by the JIC in the '50's.
    Also there is a paper published by Siemens on the importance of equi-potential bonding in electrical enclosures etc.
    It used to be available on their web site until they changed the site.
    It is available by request in PDF.
