What is the difference between ground and a groundable point?
The ESD Association standard ESD S6.1-1999 defines ground as: (1) A conducting connection, whether intentional or accidential, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of earth. (2) The position or portion of an electrical circuit at zero potential with respect to the earth. (3) A conducting body, such as the earth or the hull of a steel ship used as a return path for electric currents and as an arbitrary zero reference point.
