Electrical Wire

An electrical wire is an insulated conductor that is used to carry electricity. It is used to provide power safely to structures and buildings. An electrical wire size is determined by the American wire gauge (AWG). It calculates the diameters of a round, solid, nonferrous electrical wire. An electrical wire safety code is intended to protect people and buildings from electrical shock and possible fire hazards. These codes are established by a city, county, state or national legislation.

An electrical wire is usually color-coded to distinguish between what certain electrical wire should be used. In the United States, a black electrical wire means “hot” or “live”. A white electrical wire means neutral and a green electrical wire signifies ground or earth. An electrical wire system has specific power requirements, depending on the size of the building. For example, a single-family home will need almost minimal power requirements. Larger industries will require a higher power electrical wire.
