    The plug for SAE J560 is physically identical to the connector ISO 1185. The difference is that J560 indicates that the voltage must be 12 V and that wire areas shall be larger due to the higher currents needed when using 12 V compared to 24 V. Some of the pins in the connector have also a slightly different function.

  3. 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 ...

  4. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    NEMA 7 devices are three wire/prong (hot-neutral-ground) connectors rated at 277 V. The 15 A 7-15 plug has the crowsfoot current carrying pins of the Type I plug, but with a U-shaped earth pin. The 7-20 version has an enlarged line/hot pin. 7-30 is a larger diameter connector, with an L-shaped neutral, while the 7-50 has an enlarged neutral pin ...

    en.wikipedia.org/wiki/Electrical_conduit

    Box connectors join conduit to a junction box or other electrical box. A typical box connector is inserted into a knockout in a junction box, with the threaded end then being secured with a ring (called a lock nut ) from within the box, as a bolt would be secured by a nut.

    A blade connector is a type of single wire, plug-and-socket connection device using a flat conductive blade (plug) that is inserted into a receptacle. Wires are typically attached to male or female blade connector terminals by either crimping or soldering. Insulated and uninsulated varieties are available.

  7. 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 ...

  8. Electrical wiring in North America - Wikipedia

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

    Electrical wiring practices developed in parallel in many countries in the late 19th and early 20th centuries. [7] As a result, national and regional variations developed and remain in effect. (see National Electrical Code, electrical wiring, electrical wiring in the United Kingdom). Some of these are retained for technical reasons, since the ...

  9. 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).
