2. 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).

3. Ufer ground - Wikipedia

   en.wikipedia.org/wiki/Ufer_Ground

   It was not required to be used if a water pipe or other grounding electrode was present. In 1978, the NEC allowed 1/2 inch rebar to be used as a grounding electrode [NEC 250.52(A)(3)]. The NEC refers to this type of ground as a "Concrete Encased Electrode" (CEE) instead of using the name Ufer ground.

5. Electrical wiring in North America - Wikipedia

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

   The National Electrical Code (NEC) specifies that the black conductor represent the hot conductor, with significant voltage to earth ground; the white conductor represent the identified or neutral conductor, near ground potential; [11] and the bare/green conductor, the safety grounding conductor not normally used to carry circuit current.

6. Ground (electricity) - Wikipedia

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

   In transmitting antennas a second cause of power wastage is dielectric power losses of the electric field (displacement current) of the antenna passing through the earth to reach the ground wires. [15] For antennas near a half-wavelength high (180 electrical degrees [b]) the antenna has a voltage maximum near its base, which results in strong ...

7. Ring ground - Wikipedia

   en.wikipedia.org/wiki/Ring_ground

   A halo ground is a type of ring ground that, instead of being installed outside and underground, is installed inside, near the top of a building or structure. The ground reference for all equipment inside the area being protected is separate from the halo.
