About Electrical Panel Capacity Assessment

Before installing a home EV charger, it helps to know whether your electrical panel can handle the added load. A capacity assessment reviews the panel's size, the existing loads already in use, and the available capacity for a new dedicated circuit.

The assessment identifies whether a charger can be added directly, whether capacity needs to be freed up, or whether the panel may need upgrading. It is the planning step that prevents surprises later in the installation.
