Homes typically have several kinds of home wiring for lighting and power distribution, permanently installed and portable appliances, telephone, heating or ventilation system control, and increasingly for home theatre and computer networks. Regulations for wiring installation vary widely around the world, with national, regional, and municipal rules sometimes in effect.
In new home construction, wiring for all electrical services can be easily installed before the walls are finished. In existing buildings, installation of a new system such as a security system, or home theatre, may require additional effort to install concealed wiring. Multiple unit dwellings such as condominiums and apartment houses may have additional installation complexity in distributing services within a house.
Services commonly found include:
- Power points (wall outlets)
- Light fixtures and switches
- Television, either broadcast, cable, or satellite
High-end features might include:
- Home theatre
- Distributed audio
- Security monitoring
- Security CCTV
- Energy management
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.
