mixos Posted March 9, 2004 Report Share Posted March 9, 2004 If it is a simple low voltage circuit you haven't to ground it to real earth, just connect all grounds together. If it is a power circuit that is powered from main power (110-220V) you have to do it for protection puproses. Quote Link to comment Share on other sites More sharing options...
MP Posted March 9, 2004 Report Share Posted March 9, 2004 As Mixos has said, you would only use earth ground or case ground when the circuit requires it. Some circuits depend upon a floating voltage and will not work when the common of the circuit is tied to earth ground. If you would like to post a particular circuit or link, everyone could comment further.MP Quote Link to comment Share on other sites More sharing options...

quantum Posted June 29, 2004 Report Share Posted June 29, 2004 I heard that grounding the wire to your faucet is good idea for grounding. No matter where the grounding symbols are on the schematic, you connect all of them together, then ground them? :o Quote Link to comment Share on other sites More sharing options...
MP Posted June 30, 2004 Report Share Posted June 30, 2004 I heard that grounding the wire to your faucet is good idea for grounding.There is a catch to this, though...years ago all houses had metal pipes all connected together and going into the ground. Many newer homes in some places have plastic water pipes between the faucet and the main pipes. I have seen some with metal braiding on the flexible pipe, but the nut is plastic. Obviously, these will not connect you to the ground. If in doubt, there is nothing that beats a good old rod in the ground to be sure.MP Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted July 19, 2004 Report Share Posted July 19, 2004 This is good for a crystal radio and other radio equipment but ib little gadgets it is not needed. Ac Equipment like Satalite Recievers Cable Boxes Telephone Systems Ect. Need to be Earth Grounded.Check out this Linkhttp://www.ee.upenn.edu/rca/instruments/misctutorials/Ground/grd.html Quote Link to comment Share on other sites More sharing options...
MP Posted July 20, 2004 Report Share Posted July 20, 2004 Exactly my point. You see the term "ground" used very loosely. I work quite a bit in the meteorological field and ground is earth ground. Otherwise, you are referring to a "common".MP Quote Link to comment Share on other sites More sharing options...
