Electrical Cable

An electrical cable is an insulated conductor that is utilized to carry electricity. It is used to provide power securely to structures and buildings. An electrical cable size is determined through the American wire gauge (AWG). It determines the diameters of a round, solid, nonferrous electrical cable. An electrical cable safety code is needed 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 cable is typically color-coded to distinguish between what certain electrical cable should be used. In the United States, a black electrical cable means “hot” or “live”. A white electrical cable is neutral and a green electrical wire signifies ground or earth. An electrical cable system has specific power requirements, depending on the mass of the building. For example, a single-family home will need low power requirements. Larger companies will require a higher power electrical cable.
