Ground loop is a common wiring conditions where a ground current may take more than one path to return to the grounding electrode at the SERVICE PANEL. AC powered computers all connected to each other through the ground wire in common building wiring. Computers may also be connected by data communications cables.
A grounded system is a system in which one of the current-carrying conductors is grounded. An  equipment grounding conductor  is a conductor that does not normally carry current (except under fault conditions) and is also connected to earth.n some areas, the term earthing is used instead of grounding. A  grounded conductor  is a current-carrying conductor that normally carries current and is also connected to earth. Examples are the neutral conductor in AC wiring and the negative conductor in many DC systems.
