Amperage (Amps)
The rate of electrical current flow through a circuit.
Definition
Amperage, measured in amperes (amps), is the volume of electrical current flowing in a wire. Total panel amperage defines a home's electrical capacity.
In plain English
Modern homes typically have 200-amp service. Older homes with 100-amp service often need upgrades to support EV charging, heat pumps, or large remodels.
Example
An EV charger requires a dedicated 40- or 50-amp circuit — many older 100-amp panels can't safely add one without an upgrade.
