What gauge wire do you use when wiring a house?

Answer 1

For branch circuits (receptacles, lighting, etc.) you would use 14 gauge wire if the circuit breaker is rated for 15 amps. For 20 amp circuits, you would use 12 gauge wire. For built-in appliances such as stoves, ovens, dryers and air conditioners, the wire size depends on the specific appliance and must be determined on a case-by-case basis. The incoming power to the house (service entrance) likewise must be calculated for each house and depends on the service size.

Answer 2

Wire sizing is dependant upon the loads connected. In North America home wiring consists of #14 for lighting and branch circuits. Larger size wire for dedicated circuits (example hot water tank) will use #12, For clothes dryer #10, and for range #8. If the home has a shop #6 for a welder plug. As you can see there are many sizes of wire that are needed to completely wire a home.
