| Feb 7, 2012 at 16:10 | comment | added | TiOLUWA | @clabacchio does that mean it doesn't have to be there, but advisable? Is it possible to do without such an earth connection in the design? | |
| Feb 7, 2012 at 16:05 | comment | added | clabacchio | It's because the neutral (N is the neutral right?) is not at the same potential of the earth, and it's used for security reasons, to bring the potential of the case to the earth potential and avoid dangerous discharges over people. | |
