A home's electrical system includes the incoming power lines, electric meter, service panel, subpanels, household wiring, electrical boxes, receptacles (or outlets), switches, and, of course, the appliances that put the power to work, such as fans. Other electrical systems in a house include communications wiring for audio, video, doorbells, telephones, security systems, and intercoms.
This section of HomeTips offers information on a house's electrical systems.
