Electrical wiring in general refers to insulated conductors used to carry electricity, and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that should apply worldwide.

IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables.

a set of standard wire cross-sectional areas:

In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance. The cross-sectional area is also related to the maximum current that a wire can carry safely.

Nominal Size

This is the size of a conductor determined by its resistance rather than its physical dimensions. This is a key distinction as it makes a standardised definition of conductors based solely on their electrical characteristics.

Almost all characteristics of conductors, resistance, current carrying capacity etc are independent of the physical dimensions of the conductor. However this document allows an easy reference whereby the standard conductor sizes and reference to physical dimensions are maintained but given an exact meaning in terms of the electrical characteristics of a conductor.
