  2. Ground (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_(electricity)

    It is important to note this action occurs regardless of whether there is a connection to the physical ground (earth); the earth itself has no role in this fault-clearing process [4] since current must return to its source; however, the sources are very frequently connected to the physical ground (earth). [5] (see Kirchhoff's circuit laws). By ...

  3. Electrical wiring in North America - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_North...

    Hot is any line or neutral conductor (wire or otherwise) connected with an electrical system that has electric potential relative to electrical ground or line to neutral. Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1]

  4. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    The "local" Earth/Ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". Australian and New Zealand standards use a modified protective multiple earthing (PME [ 14 ] ) system called multiple earthed neutral (MEN).

  5. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage. [ citation needed ] Extra ground connections on a neutral conductor may bypass the protection provided by a ground-fault circuit interrupter.

  6. Earth-return telegraph - Wikipedia

    en.wikipedia.org/wiki/Earth-return_telegraph

    Earth-return telegraph is the system whereby the return path for the electric current of a telegraph circuit is provided by connection to the earth through an earth electrode. Using earth return saves a great deal of money on installation costs since it halves the amount of wire that is required, with a corresponding saving on the labour ...

  8. Isolated ground - Wikipedia

    en.wikipedia.org/wiki/Isolated_ground

    An isolated ground (IG) (or Functional Earth (FE) in European literature) is a ground connection to a local earth electrode from equipment where the main supply uses a different earthing arrangement, one of the common earthing arrangements used with domestic mains supplies.
