<onlyinclude>'''Insulation''' is the term used for a variety of materials used to reduce the transfer of energy. Insulation is used around electric [[wire]]s to protect the wire from the environment or the environment (like people) from the wire. It is a key safety feature in wiring.</onlyinclude> Exposure to water can corrode wires, increasing their [[resistance]], which in turn creates heat buildup the system was not designed for - potentially causing fires. Furthermore, separating the wire from its external environment prevents the flow of charge out of the wire in places it is not supposed to go, like a person who touches the wire.

As seen in figure 1, insulation can be used to communicate what a particular wire is being used for, is it the [[hot line]], the [[neutral line]] or the [[ground]] line.
