electrosimonics Posted October 22, 2006 Report Share Posted October 22, 2006 Hello everyone , I just wanna know the difference between ( neutral , ground & earth ) nodes . So if any1 know the difference plz tell me . Thx a lot . Quote Link to comment Share on other sites More sharing options...
mvs sarma Posted October 22, 2006 Report Share Posted October 22, 2006 Hi electrosimonics to best of what i could recollectNEUTRAL is used for public mains supply, either single phase (Live & neutral) or three phase Star connection ,4th wire being neutral. the concerned electrical supply companies general connect the neutral to ground at the point of thier distribution stepdown Transformer' output. It need not essentially be at earth potential by the time it reaches the user premises, but will be near to ground Ground and earth are similar words-- i saw the term ground being used in American documentation especially.sarma Quote Link to comment Share on other sites More sharing options...
MP Posted October 23, 2006 Report Share Posted October 23, 2006 "Ground" and "Earth" are actually two different things, but can be at the same potential. In other words, the ground of your circuit does not have to be connected to earth ground, which is the potential of the return or ground of the mains in your service box on the house. This is always at Earth Ground because it is connected to a rod that is driven into the ground. There are many situations where your chassis ground or case ground on the instrument would not be at the same potential as earth. There are also instances where you want a different supply ground or circuit ground than the earth ground or the chassis ground. Thus terms such as chassis ground and common come into play. When these potentials are different, the schematic will use different symbols to denote zero volts, common, analog ground, digital ground, chassis ground, and earth ground. Using different symbols to sort these out keeps this from getting too confusing.MP Quote Link to comment Share on other sites More sharing options...

The Master Posted October 23, 2006 Report Share Posted October 23, 2006 Hi Folks, is VERY deadly and once touched accidently it can at the very least make you break-dance from the shock or at the other end of the spectrum , it can kill you "stone dead" instantly.I have a page specifically directed at mains voltages, 240 Volts AC to be exact, which here in Australia Quote Link to comment Share on other sites More sharing options...
