Home Electrical Essentials | Best Pick Reports

Electricity is delivered to the home by either underground or overhead service wires. After going through the electric meter, the wires enter the service panel (also called the main fuse box or the main electric panel). Starting at the service panel, different circuits or loops connect to different parts of the house. Standard circuits, or 120-volt circuits, power items such as lights and standard wall outlets. Heavy-duty circuits, or 240-volt circuits, power items such as kitchen appliances, electric dryers, and air conditioning equipment. Although some older houses still have 60-amp service, 200-amp service is typical in most houses.
