Electrical conductor
- Copper is the electrical conductor in many categories of electrical wiring. [ 3][ 4] Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. [ 5] Copper and its alloys are also used to make electrical contacts.

In a copper atom, the outermost 4s energy zone, or conduction band, is only half filled, so many electrons are able to carry electric current. When an electric field is applied to a copper wire, the conduction of electrons accelerates towards the electropositive end, thereby creating a current.

- NM Cable. Best for: Interior use in dry locations. Often called “Romex” after one popular brand name, nonmetallic (NM) cable is a type of circuit wiring designed for interior use in dry locations.
- UF Cable. Best for: Underground wire for outdoor fixtures. Underground Feeder (UF) is a type of nonmetallic cable designed for wet locations and direct burial in the ground.
- THHN/THWN Wire. Best for: Wiring inside of conduit in exposed, often unfinished, areas of the home. THHN and THWN are codes for the two most common types of insulated wire used inside conduit.
- Low-Voltage Wire. Best for: Circuits requiring 50 volts or less. Low-voltage wiring is used for circuits typically that require minimal voltage, such as landscape lighting wires, sprinkler system connections, bell wires (for doorbells), speaker system wires, thermostat wires, or anything else that requires 50 volts or less.
