2. Electrical wiring in North America - Wikipedia

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

   In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...

3. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [1] The cross-sectional area of each gauge is an important factor for ...

   Single-phase 6-50 is commonly used on farms for silo unloaders, and is used with a 6-gauge flexible power cord up to 200 ft (61 m) long. The 6-50 receptacle charges electric vehicles at the same 32- or 40-ampere maximum from charging stations, on a short cord, as the more versatile 14-50 with its fourth prong neutral not used currently for any ...

5. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈkoʊ.æks /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. The term coaxial refers to the inner conductor and the ...

6. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended ...

7. RG-6 - Wikipedia

   RG-6 coaxial cable for television signals. RG-6 coaxial cable. RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another ...
