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

Typical features

Single-phase ~230V/40A/9kW fuse box for apartment rewiring. Each appliance and each room are highlighted into autonomous circuits - this apartment has 14 individual circuits. A relay is used to control the light fixtures in a large room.

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

Telephone

Internet

Television, either broadcast, cable, or satellite

High-end features might include:

Home theater

Distributed audio

Security monitoring

Security CCTV

Automation

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.

How services are connected will vary depending on the service provider and location of the home.
