2. Copper-clad aluminium wire - Wikipedia

   en.wikipedia.org/wiki/Copper-clad_aluminium_wire

   A copper strip is formed into the shape of a cylinder, while it is being wrapped around an aluminum core and the edges of the copper strip are welded together. The assembly is then pulled through a die, where the cladded wire is squeezed and stretched while also improving the bonding between the copper and the aluminum core. [1]

3. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric ...

4. Aluminum building wiring - Wikipedia

   en.wikipedia.org/wiki/Aluminum_building_wiring

   Aluminum building wiring. Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids, including overhead power transmission lines and local power ...

5. Electrical wiring in North America - Wikipedia

   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 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.

6. ISO standards for trailer connectors - Wikipedia

   en.wikipedia.org/wiki/ISO_standards_for_trailer...

   Trailer connectors between the trailer and passenger car, light truck or heavy trucks with 12V systems. In Europe, both 7-pin (ISO 1724) and 13-pin (ISO 11446) are common. The 13-pin version being phased in is newer, provides more services than the 7-pin, a more positive locking and also better protection against moisture and contamination.

7. Electrical conductor - Wikipedia

   en.wikipedia.org/wiki/Electrical_conductor

   The main grade of copper used for electrical applications, such as building wire, motor windings, cables and busbars, is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C100140). If high conductivity copper must be welded or brazed or used in a reducing atmosphere, then oxygen-free high conductivity copper (CW008A or ASTM ...
