Do I always need an electrical panel upgrade for a Level 2 EV charger in San Antonio?

Not always. Some homes have enough spare panel capacity and an open breaker space to add a dedicated 240V circuit without upgrading. Older 100-amp panels, full panels, or heavily loaded homes may need an upgrade. A licensed load calculation is the reliable way to know.

What kind of circuit does a Level 2 EV charger need?

A Level 2 charger typically requires a dedicated 240V circuit. Depending on the specific charger, that circuit is often rated around 40 to 60 amps, with breaker and wiring sized to manufacturer requirements and code.

Do I need a permit to install an EV charger in San Antonio?

Installing a new 240V dedicated circuit or hardwired Level 2 charger generally requires an electrical permit, and any panel or service upgrade typically needs its own permit and inspection.

Can C.S.W. Power Solutions handle the charger and panel upgrade together?

Yes. C.S.W. Power Solutions can evaluate the panel, run the load calculation, plan any panel or service upgrade, handle permitting, coordinate CPS Energy when needed, and install the Level 2 EV charger.
