What is amperage?
Amperage (or amps) is the measure of electrical current flow in a circuit, typically expressed in units of amperes and determined by a home's electrical service panel rating.
Amperage refers to the amount of electrical current flowing through a circuit, measured in amperes or amps. It represents how much electricity is moving through your home's wiring at any given moment. Every electrical device draws a certain amount of current when it operates, and your home's main service panel controls the total current allowed into the house.
Residential electrical service in Sanford is typically delivered at 100, 150, or 200 amps, depending on the home's size, age, and power demands. Older homes often have 100A service, while modern homes built in the last 20 years usually have 150A or 200A. The amperage rating of your service panel directly limits how much current can enter your home safely. If you try to draw more current than your panel allows, the main breaker trips and cuts power to protect the wiring from overheating.
The relationship between amperage and panel capacity is straightforward: your service panel's amp rating is its maximum capacity. A 200A panel can supply up to 200 amps of current total to all circuits and appliances in your home. When homes add major loads like electric vehicles, heat pumps, or large HVAC systems, they often outgrow their existing panel capacity. This is why electrical panel upgrades become necessary. An electrician can assess your current amperage needs and determine whether an upgrade is required to safely power your home's electrical equipment.
