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. Some places allow the homeowner to install some or all of the wiring in a home; other jurisdictions require that licensed electricians only install wiring.
