  2. Isolated ground - Wikipedia

    en.wikipedia.org/wiki/Isolated_ground

    The primary reason for the use of isolated grounds (IG) is to provide a noise-free ground return, separate from the equipment grounding (EG) return. The EG circuit includes all of the metal conduit, outlet boxes, and metal enclosures that contain the wiring and must be grounded to provide a safe return path in case of fault currents.

  3. Three-prong adaptor - Wikipedia

    en.wikipedia.org/wiki/Three-prong_adaptor

    The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

  4. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    A ground conductor only carries significant current if there is a circuit fault that would otherwise energize exposed conductive parts and present a shock hazard. In that case, circuit protection devices may detect a fault to a grounded metal enclosure and automatically de-energize the circuit, or may provide a warning of a ground fault.

  5. 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]

  6. AC power plugs and sockets - Wikipedia

    en.wikipedia.org/wiki/AC_power_plugs_and_sockets

    Grounded vs ungrounded NEMA plugs. The NEMA 5-15 plug has two flat parallel blades like NEMA 1-15, and a ground (earth) pin. [46] It is rated 15 A at 125 volts. The ground pin is longer than the line and neutral blades, such that an inserted plug connects to ground before power. The ground hole is officially D-shaped, although some round holes ...

  7. Electrical fault - Wikipedia

    en.wikipedia.org/wiki/Electrical_fault

    In transmission line faults, roughly 5% - 10% are asymmetric line-to-line faults. [2] line-to-ground fault - a short circuit between one line and ground, very often caused by physical contact, for example due to lightning or other storm damage. In transmission line faults, roughly 65% - 70% are asymmetric line-to-ground faults. [2]

  8. Industrial and multiphase power plugs and sockets - Wikipedia

    en.wikipedia.org/wiki/Industrial_and_multiphase...

    The designations of the three contacts may vary. The IEC standards use the Line designations L1, L2 and L3. [15] NEMA standards use the Phase designations X, Y and Z. [16] Sockets intended for use with the American split Phase distribution system may have two line contacts and neutral. In this case the line designators X and Y are used. [16]

  9. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    Presence of uninterrupted ground fault may pose a significant safety risk: if the current exceeds 4 A – 5 A an electric arc develops, which may be sustained even after the fault is cleared. [28] For that reason, they are chiefly limited to underground and submarine networks, and industrial applications, where the reliability need is high and ...
