Electrical wire carries an electric current or grounds an electrical device..It is nominally composed of 80 percent nickel and 20 percent chromium and meets ASTM B267 standards for resistance wire. The amount of current a wire can carry is proportional to its size (gauge), and the wire is generally sheathed with coatings and coverings to insulate and protect it from moisture, chemicals, heat, and abrasion.
