  2. Stage pin connector - Wikipedia

    en.wikipedia.org/wiki/Stage_pin_connector

    A newer stage pin connector. Note the GR denoting the longer ground pin, which is slightly off-center to prevent the plug being inserted upside down.. A stage pin connector, also known as a grounded stage pin (GSP), grounded pin connector (GPC) or theater paddle (TP), is a standard cable type for theatrical lighting in North America and in many countries in the theatre world.

  3. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).

  4. Counterpoise (ground system) - Wikipedia

    en.wikipedia.org/wiki/Counterpoise_(ground_system)

    The ground connection must have a low electrical resistance, because it carries the full antenna current and any resistance in the ground connection will dissipate power from the transmitter. Low-resistance grounds for radio transmitters are normally constructed of a network of cables buried in the earth.

  5. Cable gland - Wikipedia

    Sometimes both ends of a cable are terminated with the same gender of connector, as in many Ethernet patch cables. In other applications the two ends are terminated differently, either with male and female of the same connector (as in an extension cord ), or with incompatible connectors, which is sometimes called an adapter cable .

  7. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    Therefore, TN-C connections must not go across plug/socket connections or flexible cables, where there is a higher probability of contact problems than with fixed wiring. There is also a risk if a cable is damaged, which can be mitigated by the use of concentric cable construction and multiple earth electrodes. Due to the (small) risks of the ...

  8. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.

  9. Aluminum building wiring - Wikipedia

    en.wikipedia.org/wiki/Aluminum_building_wiring

    The splice of the copper pigtail to the existing aluminum wire can be accomplished with special crimp connectors, special miniature lug-type connectors, or approved twist-on connectors (with special installation procedures). Pig-tailing generally saves time and money, and is possible as long as the wiring itself is not damaged.
