Adding a dedicated circuit for an electric vehicle is one of the fastest ways to pull real load on an older panel. Lewis Electric and Contracting plans the work around your charger model, your garage or driveway layout, and the spare capacity already present at the meter. We serve Aurora, Naperville, Plainfield, Oswego, and nearby suburbs with the same tidy workmanship we bring to every service upgrade call.
How we plan your charger circuit
- Confirm the charger type. Portable cords with a NEMA 14-50 plug, hardwired wall units, and smart chargers each need the right breaker size, wire gauge, and physical route from the panel.
- Measure spare capacity. We add continuous loads at the required demand factor so the service does not run hot when the car charges overnight alongside air conditioning or kitchen appliances.
- Pick the path. Garages often need surface metal raceway, bored joists, or exterior short cuts. We mark stud locations, keep cable protected, and avoid pinch points at garage doors.
- Install grounding and overcurrent protection. New circuits receive GFCI protection where the adopted code calls for it, proper neutral sizing for certain charger brands, and labels at the panel that read “EV” for the next inspector or buyer.
- Test under load. After termination we verify voltage at the equipment, torque set screws to manufacturer values, and show you how to monitor charging from the vehicle app.
When the panel needs attention first
Many 100 amp services can host a 32 or 40 amp charger if other large loads are managed. If your main breaker is already warm, if breakers trip when the dryer runs, or if the inspection report calls out double taps, we discuss a service increase before the charger lands. That sequence keeps you from paying twice for drywall repairs. Read more about our approach on the About page, then call 630-688-6116 with your vehicle model and charger paperwork.
Permits, inspections, and utility paperwork
Most towns in Kane and DuPage counties require an electrical permit for new EV branch circuits. We file the permit, coordinate rough inspection if the AHJ requires it, and leave you with photos of the completed work. If your utility offers a rebate, we can supply the photos and panel schedule they often request.
Book a site visit
Send photos of your panel cover, the garage wall where you want the charger, and the driveway approach. We reply with a ballpark range when possible, then firm pricing after a short site visit. You can also use the free quote request form so we can match you with the next open appointment.
