"Electrical wire" is a catch-all term that refers to conductors which route electricity from a power source to lights, appliances, and other electrical devices. A conductor is a material that allows electric current to flow through with very little resistance. Copper is the most commonly used material for electrical conductors used in home wiring; aluminum is occasionally used, too. Conductors used for carrying electrical current have an outer sheath of insulation to prevent against the unwanted transfer of electricity (this insulation is stripped from the ends of the wires where connections are made). Bare (non-insulated) conductors are used for grounding.
In this section, you will find helpful information for safely working with electrical wiring.
