Electrical Wiring Electrical wire is typically made of copper or aluminum wiring because of it’s conductivity and availability.

Residential Wiring Panel Feed Wires These wires are also type THHN, like the main feeders. A typical 100-amp service would have a #2 THHN set of wires. They would then be rated at 125 amps. This would protect the wires if the amperage was a full 100 amps.

Residential Wiring Non-metallic sheathed wire. commonly called Romex, is a plastic coated wire that has either two or three conductors and a bare ground wire. This is the typical wiring used in most homes. The rating for this wire is either 15 amps, 20 amps, or 30 amps, depending on the installation.

Insulated Wiring Wiring is coded with a nylon or rubberized plastic to protect the wires from contacting other conductor and causing shorts in the circuit and possible fire.

Typical Wiring Gauge for Homes 12 gauge wiring is the typical wiring for all homes.
