Electricity plays an essential role in how your home operates. Whether watching TV, powering heating and cooling systems, or charging a cell phone, we rely on our home’s electrical system to provide us with power when and where we need it.

By understanding the basics of how electricity is distributed around your home, you can keep this important system properly maintained and in safe working condition.

Electricity enters your home through a service head from a series of outdoor power lines or an underground connection. A typical service head consists of two 120-volt wires and one neutral wire that deliver power to lights and appliances around the home.
