A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
The most commonly used insulation type in AC electrical distribution systems throughout North America is THHN ("Thermoplastic High Heat-resistant Nylon-coated" [17]). This is a specification for PVC insulation (other thermoplastics are permitted, but rarely used) with a nylon jacket for abrasion resistance. THHN is suitable for dry or damp ...

Homes typically have several kinds of home wiring, including electrical wiring for lighting and power distribution, permanently installed and portable appliances, telephone systems, heating or ventilation system control, and increasingly for home theatre and computer networks.
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 designated by the number of zeros: No. 0, often written 1/0 and referred to as "one aught" wire
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]
In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission (IEC)'s international standard on electrical installations of buildings.This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364".
