Look for the point at which the main service wires from the utility company enter the home. If electrical service is delivered by overhead wires, they will enter a metal service pipe that runs down an exterior wall of your home to the meter. If the meter is a glass dome mounted on a square metal base, the home probably has 100 amps of power, while a newer 150-amp or larger service will have a rectangular base that extends below the glass dome.
How does electrical service reach your home?
Electrical service reaches your home from the power utility through two 120-volt service wires that offer a combined 240 volts of power (voltage is a measurement of electricity's pressure or rate of flow).
