The term “wire” and “cable” are often used interchangeably – but that’s incorrect. At their very basic, a wire is a single conductor that moves electrical current through a circuit. A cable is a collection of wires that are shielded together. Typically, cables may have a hot wire, neutral wire and a ground wire.
The various types of electrical wiring may include those made from copper or aluminum, and may come as bare or insulated (shielded) versions. When shielded in PVC sleeves, wires must be color coded to signify whether they are ground, hot or neutral. There are a number of different types of home electrical wire based on the various types of application.

The most common electrical wire types include:
Like their electrical wire counterparts, electrical cable types too vary based application, design and construction. Some of the most common types of electrical cables include
NM-B Cable – “NM” stands for non-metallic, UF Cable – ”UF” stands for underground feeder, “AC” means armored cable – also known as “BX.” Other types of cables include Metal-clad Cable, Coaxial Cable, HDMI (High Definition Multimedia Interface) Cable, Speaker Cable and Category 5e Cable.
