NEMA 5-15P plug and NEMA 5-15R receptacle (different scales, blade spacing is 0.5 inches (12.7 mm) for both.) Each receptacle also accepts an ungrounded plug, whether polarized or unpolarized. Typical 5-15R residential receptacle 5-20R T-slot receptacle mounted with the hole for the ground pin at the top. The neutral connection is the wider T ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
[5] [6] The design was based on an American plug and socket-outlet first intended for use at 120 V which was patented in 1916 under U.S. patent 1,179,728 by Harvey Hubbell. [7] By the early 1930s this design had been up-rated to 250 V 10 A capacity and Hubbell had supplied the Australian electrical industry with his sockets. [ 8 ]
Leviton was founded in 1906 by Russian immigrants Evser Leviton and his son Isidor Leviton when they began manufacturing brass mantle tips for natural gas lights in Manhattan's Lower East Side. [ 2 ] [ 3 ] [ 4 ] In 1910, Isidor designed a screw-in lampholder for the newly invented electric light bulb and within ten years the lampholders were ...
The most common cable used for this is a Category 5 cable. The cable can be installed in either a daisy chain or star wired configuration. The importance is to minimize the cable length to avoid a communications problem on the bus.
These sockets include CEE 7/1, CEE 7/3 (German/"Schuko") and CEE 7/5 (French). Most Israeli, Swiss, Danish and Italian sockets were designed to accept pins of various diameters, mainly 4.8 mm, but also 4.0 mm and 4.5 mm, and are usually fed by final circuits with either 10 A or 16 A overcurrent protection devices.

[4] Special feedthrough twist-on wire connectors differ from standard wire connectors in that they have an additional opening at the top of the insulated cap. This allows a single-conductor bare wire to be pushed through the hole, forming a "pigtail" section which can be attached to a grounding screw.
