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 ...
NEMA L6 connectors are rated for a maximum of 250 volts. They are intended for two-pole, three wire, line-line-earth (or hot-hot-ground) circuits with a nominal supply voltage of 208 or 240 volts, depending on phase configuration. The L6 connector does not provide a neutral connection.
The plugs and sockets used in a given area are regulated by local governments. The International Electrotechnical Commission (IEC) maintains a guide with letter designations for generally compatible types of plugs, [7] which expands on earlier guides published by the United States Department of Commerce.
Twist-on wire connectors. Twist-on wire connectors are a type of electrical connector used to fasten two or more low-voltage (or extra-low-voltage) electrical conductors. They are widely used in North America and several European countries in residential, commercial and industrial building power wiring, but have been banned in some other ...
Wire is manufactured in a range of conductor sizes, stranding, and materials (copper or aluminum), [15] but the term "wire type" usually refers to the insulation, which determines the environments in which the wire may be used. Wire types for North American wiring practices are defined by standards issued by Underwriters Laboratories, the ...
Appearance. CEE 7 is a standard for alternating-current plugs and sockets. First published in 1951 by the former International Commission on the Rules for the Approval of Electrical Equipment (IECEE), it unified standards produced by several continental European countries. The 2nd edition was published in 1963 and last updated in March 1983.

Aluminium-conductor steel-reinforced cable. Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.
