While the terms Electric wire and Electric cable are often used interchangeably, technically wire is one electrical conductor and cable is a group of wires (or conductors), encased in sheathing.
The National Electrical Code (NEC) and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation.
Check with your local building inspector before you start any electrical wiring and cable project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.
There are two main types of wires: solid or stranded. A solid wire is usually a long length of single conductor. A stranded wire is many thin strands of wires twisted together. Solid wires offer low resistance and are perfect for use in higher frequencies, whereas a stranded wire has a longer life, due to its flexibility and can be used for a longer period than a single conductor. Wires are mainly used to carry electrical and telecommunications signals, but can also be used in various other forms, from bearing mechanical loads, to heating, to even in jewelry and clothing.
A Electric Cable is usually two or more wires running together or bonded, twisted or braided together. They are usually insulated rather than not, which gives them a better protection than just wires. Cables are mainly used to carry electrical and telecommunications signals.
