Home wiring is the application of electrical wiring for houses. It includes wiring for lighting and power distribution, permanently installed and portable appliances, telephone systems, heating or ventilation system control, and increasingly, for home theatre and computer networks.

Safety regulations for wiring installation vary widely around the world, with national, regional, and municipal rules sometimes in effect. Some places allow homeowners to install some or all of the wiring in a home; other jurisdictions require electrical wiring to be installed by licensed electricians only.

In new home construction, wiring for all electrical services can be installed before the walls are finished. In existing buildings, installing a new system, such as a security system or home theater, may require additional effort to install concealed wiring. Multiple-unit dwellings, such as condominiums and apartment houses, may have added complexity in distributing services within the building.

Power and telecommunication services generally require entry points into the home and a location for connection equipment. For electric power supply, a cable is run either overhead or underground into a distribution board in the home. A distribution board, or circuit breaker panel, is typically a metal box mounted on a wall of the home. In many new homes, the location of the electrical switchboard is on the outside of the external wall of the garage.
