There are several various types of each electrical wire that are available today. Every electrical wire is designed for a certain application. Some examples of electrical wire include THHN, Romex, 500 MCM wire, UFB cable and bare copper. Each of these electrical wires is made differently in order to best work with whichever project it was made for. For example, THHN wire is a single conductor copper electrical wire that has PVC insulation with nylon coating. A THHN electrical wire is the foundation to start a number of electrical cables.
An additional type of electrical wire is a Romex cable. This type of cable has more than one THHN electrical wire with a bare copper ground. Romex electrical wire was particularly constructed so that more than one THHN electrical wire can be attached to an electrical box. This is beneficial if you require a large amount of lighting or have several appliances. Before purchasing any electrical wire, such as a 500 MCM wire, be sure to research what kind of wire you need for your particular project.
