Amperage
Definition and meaning of Amperage in real estate.
Amperage is the measure of the volume or rate of electrical current flowing through an electrical circuit, expressed in amperes.
In more detail
In real estate and home construction, the overall amperage of a home's electrical panel determines how much electrical equipment can run simultaneously. Older homes may only have 60-amp or 100-amp service, which can be insufficient for modern appliances like central air conditioning, electric vehicle chargers, and electric stoves.
Upgrading to a 200-amp service is common during remodeling to prevent overloaded circuits and potential fire hazards. Home inspectors check the panel's amperage capacity and wire sizes to verify that the system is safe and adequate for the household's needs.
Key facts
| Category | Property Types & Construction |
|---|---|
| Standard capacity | 100 to 200 amps for residential properties |

| Watch out for | Overloaded circuits or outdated electrical panels |
A home buyer requests an electrical upgrade to 200-amp service to accommodate a new electric vehicle charging station in the garage.
Frequently asked questions
How can I tell the amperage of my home's electrical panel?
The main breaker switch, usually located at the top or bottom of the service panel, typically has a number stamped on it indicating the total amperage.
Is 100-amp service enough for a typical house?
While 100 amps is sufficient for small to medium homes with gas appliances, larger homes or those with all-electric appliances usually require 200 amps.
