2. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   AWG is colloquially referred to as gauge and the zeros in thick wire sizes are referred to as aught / ˈ ɔː t /. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are ...

3. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   A grounded wire is sometimes strung along the tops of the towers to provide lightning protection. An optical ground wire is a more advanced version with embedded optical fibers for communication. Overhead wire markers can be mounted on the ground wire to meet International Civil Aviation Organization recommendations. [6]

4. Electrical wiring in North America - Wikipedia

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

   NEC 2008 400.22(f) allows surface marking with ridged, grooves or white stripes on the surface of lamp cord. With transparent cord the hot wire is copper colored, and the neutral is silver colored. Grounding wire of circuit may be bare or identified insulated wire of green or green having yellow stripes. All metallic systems in a building are ...

5. Copper-clad steel - Wikipedia

   en.wikipedia.org/wiki/Copper-clad_steel

   Copper-clad steel (CCS), also known as copper-covered steel or the trademarked name Copperweld is a bi-metallic product, mainly used in the wire industry that combines the high mechanical strength of steel with the conductivity and corrosion resistance of copper. It is mainly used for grounding purposes, line tracing to locate underground ...

6. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   For instance, instead of 14 AWG (American wire gauge) copper wire, aluminium wiring would need to be 12 AWG on a typical 15 ampere lighting circuit, though local building codes vary. Solid aluminium conductors were originally made in the 1960s from a utility-grade aluminium alloy that had undesirable properties for a building wire, and were ...

7. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   An example of a copper alloy conductor is cadmium copper wire, which is used for railroad electrification in North America. [5] In Britain the BPO (later Post Office Telecommunications ) used cadmium copper aerial lines with 1% cadmium for extra strength; for local lines 40 lb/mile (1.3 mm dia) and for toll lines 70 lb/mile (1.7 mm dia).

9. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   This does not include the uninsulated ground wire. For instance, if the cable lists "12-2 AWG", it means there are two insulated 12-gauge wires (a black and a white wire), plus a ground wire. If the label says "12-3", this cable has four conductors—three 12-gauge insulated wires and a bare copper ground wire. [5]
