Rule of thumbRecommended
EV charger conduit / panel space
EV-CHARGER-PREPDescription
Run conduit from the electrical panel to the garage (or carport) and reserve panel space for a 240V circuit, even if no EV charger is installed today.
Why this exists
5-10 year time horizon: most new houses will need EV charging. Conduit during framing costs ~$200; retrofit costs $2,000+.
