Question

Explain the electrical wiring in our house and other related important points

Answer 1

Homes typically have several kinds of home wiring, including Electrical 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. 

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.
