2. Ground (electricity) - Wikipedia

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

   The "protective earth" (PE) safety ground wires in AC utility building wiring were not designed for, and cannot be used as an adequate substitute for an RF ground. The long utility ground wires have high impedance at certain frequencies. In the case of a transmitter, the RF current flowing through the ground wires can radiate radio frequency ...

3. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   While the national wiring regulations for buildings of many countries follow the IEC 60364 terminology, in North America (United States and Canada), the term "equipment grounding conductor" refers to equipment grounds and ground wires on branch circuits, and "grounding electrode conductor" is used for conductors bonding an earth/ground rod ...

4. 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]

5. Stray voltage - Wikipedia

   en.wikipedia.org/wiki/Stray_voltage

   Stray voltage is a result of the design of a 4 wire distribution system and as such has existed as long as such systems have been used. Stray voltage became a problem for the dairy industry some time after electric milking machines were introduced, and large numbers of animals were simultaneously in contact with metal objects grounded to the ...

6. Ground and neutral - Wikipedia

   en.wikipedia.org/wiki/Ground_and_neutral

   There are special provisions in the NEC for so-called technical equipment, mainly professional grade audio and video equipment supplied by so-called "balanced" 120 volt circuits. The center tap of a transformer is connected to ground, and the equipment is supplied by two line wires each 60 volts to ground (and 120 volts between line conductors).

7. Ground loop (electricity) - Wikipedia

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

   The ground potential at different outlets may differ by as much as 10 to 20 volts [4] due to voltage drops from these currents. The diagram shows leakage current from an appliance such as an electric motor A flowing through the building's ground system G to the neutral wire at the utility ground bonding point at the service panel.
