How Your House Works Electrical Systems
Electricity is a wonder. Little more than a century ago, Alexander Graham Bell, Guglielmo Marconi, and Thomas Edison captured this force that is present in all matter and put it to work. Now electricity zings through wires to power the many conveniences that make our lives comfortable.
A home's electrical system includes the incoming power lines, electric meter, service panel, sub-panels, 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.
