  3. Ground (electricity) - Wikipedia

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

    A typical earthing electrode (left of gray pipe), consisting of a conductive rod driven into the ground, at a home in Australia.Most electrical codes specify that the insulation on protective earthing conductors must be a distinctive color (or color combination) not used for any other purpose.

  4. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    System earthing serves a purpose of electrical safety throughout the system that is not caused by a short circuit or other electrical fault.It prevents static buildup and helps protect (as part of a surge protection system) against power surges caused by nearby lightning strikes or switching.

  5. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    Normal circuit currents flow only in the neutral, and the protective earth conductor bonds all equipment cases to earth to intercept any leakage current due to insulation failure. The neutral conductor is connected to earth at the building point of supply, but no common path to ground exists for circuit current and the protective conductor.

  9. Electrical bonding - Wikipedia

    en.wikipedia.org/wiki/Electrical_bonding

    This is done in the UK because many buildings are supplied with a TN−C−S earthing system where the neutral and earth conductors are combined. Close to the electricity meter this conductor is divided into two, the earth and the neutral busbar in the consumer unit. If the ground connection to the neutral is lost, all wiring and other objects ...
