  2. Bonding jumper - Wikipedia

    en.wikipedia.org/wiki/Bonding_jumper

    [2] Some codes require a bonding jumper to be pulled into non-metallic conduit or in electrical metallic tubing that may be exposed to corrosion or mechanical damage. In North American electrical codes, an important bonding jumper is found in main electrical panels, where the system neutral conductor is connected to earth ground. This must be ...

  3. Jump wire - Wikipedia

    en.wikipedia.org/wiki/Jump_wire

    Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...

  4. 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).

  5. Electrical conduit - Wikipedia

    en.wikipedia.org/wiki/Electrical_conduit

    Sometimes the fittings are considered sufficiently conductive to bond (electrically unite) the metal conduit to a metal junction box (thus sharing the box's ground connection); other times, grounding bushings are used which have bonding jumpers from the bushing to a grounding screw on the box.

  6. Electrical bonding - Wikipedia

    en.wikipedia.org/wiki/Electrical_bonding

    Equipotential bonding involves electrically connecting metalwork so that it is at the same voltage everywhere. Exact rules for electrical installations vary by country, locality, or supplying power company. [2] Equipotential bonding is done from where the distribution wiring enters the building to incoming water and gas services.

  7. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    Grounding connectors. Connectors for earthing installation are a means of communication between the various components of the earthing and lightning protection installations (earthing rods, earthing conductors, current leads, busbars, etc.). For high voltage installations, exothermic welding is used for underground connections.

  9. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    NEMA L14 are three-pole and ground connectors rated for 125/250 V. Intended for three-pole, four-wire hot-hot-neutral-ground circuits with a nominal supply voltages of 240 or 208 V hot-to-hot and 120 V hot-to-neutral. These connectors are common on household backup generators, and on racks of power amplifiers in large audio systems.
