Home Electrical Service

our home’s electrical system is more than just a bunch of wires – it’s a complex system, carefully designed to deliver all the power you need for modern life in the safest way possible. Knowing how your home’s electrical system works will help you be a more “empowered” homeowner.

Electrical System Components

The electrical system consists of the line from the pole, a meter where electrical usage is tallied, a main circuit breaker panel (sometimes called “load centers” and, in older homes, fuse panels), separate wiring circuits to all the rooms in the home, outlets, light fixture boxes, and various hard-wired appliances.

The main line typically comes off a pole (but can also be buried underground) to the house where it connects to the meter. Meters are typically installed on the exterior of the home, where they can be read by utility company meter-readers. Most meters are mechanical, with a spinning wheel and mechanical display of numbers. Some newer meters are digital, showing a display on an LCD screen. The meter tallies the amount of electricity used in a home in units of kilowatt hours (kWh). The total increase in the number of kWh from one month to the next is the number used by the electric utility for your bill.
