  2. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.

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

    Grounding (earthing) of distribution circuits is a notable difference in practice between wiring systems of the United States and those of other regions. Since the early 1960s, wiring in new construction has required a separate grounding conductor used to bond (electrically connect) all normally non-current carrying parts of an electrical ...

  4. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    In electrical engineering, ground and neutral (earth and neutral) are circuit conductors used in alternating current (AC) electrical systems. The neutral conductor returns current to the supply. To limit the effects of leakage current from higher-voltage systems, the neutral conductor is often connected to earth ground at the point of supply.

  5. Ground (electricity) - Wikipedia

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

    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.

  6. Electrical safety standards - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_standards

    The electrical safety develops with the technical progress. In 1989 OSHA [1] promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2] In 1994 were established Electrical ...
