What EV charger installation involves
A Level 2 home charger needs a dedicated 240V circuit — the same voltage your dryer or oven uses. The circuit runs from your main electrical panel to the charger location (garage wall, carport post, or exterior wall near the driveway). Per NEC Article 625, the breaker must be rated at 125% of the charger's maximum draw: a 40A charger needs a 50A breaker on 6 AWG copper wire, a 48A charger needs a 60A breaker on 4 AWG.
We start with a site survey — checking your panel capacity, measuring the wire run distance from panel to charger location, and identifying routing options (attic, crawlspace, or surface-mounted conduit). If your panel is in the basement and the charger is in a detached garage 60 feet away, the job is very different from a panel-in-the-garage setup. We give you a fixed-price quote after the survey, not a range.
Installation day, we mount the charger, run conduit and wire, install the breaker, and connect everything. We test the circuit with a meter before powering up, then run a full charge cycle to verify the charger communicates with your vehicle. If you're using a smart charger (ChargePoint, JuiceBox), we help you set up the app and configure off-peak scheduling to take advantage of Georgia Power's lower nighttime rates.
What affects the cost
EV charger installation in the Atlanta area runs $500–$2,500 for labor and materials (charger unit priced separately at $400–$700). The biggest cost drivers are distance from panel to charger and whether your panel has capacity.
| Scenario | Cost | Time |
|---|---|---|
| Panel in garage, short run (<15 ft) | $500–$800 | 2–3 hrs |
| Standard run (20–40 ft conduit) | $1,000–$1,500 | 3–5 hrs |
| Long run to detached garage (50+ ft) | $1,500–$2,500 | 5–8 hrs |
| Panel upgrade required (100A → 200A) | + $1,500–$3,500 | + 4–6 hrs |
Permit fee ($75–$125) included in all quotes. Charger unit priced separately. Federal tax credit covers 30% of total installed cost up to $1,000.
Choosing the right charger
We install all major brands. The right choice depends on your vehicle, whether you need WiFi/app control, and your budget. Here are the models we install most often in the Atlanta area:
Tesla Wall Connector
48A · $450–$500
Best for Tesla owners. Power sharing between multiple units.
ChargePoint Home Flex
16–50A · $600–$700
Adjustable amperage. Works with any EV. WiFi + app control.
JuiceBox 40
40A · $500–$600
WiFi scheduling. Works with all J1772 EVs. Solid mid-range.
Grizzl-E Classic
40A · $400–$500
No smart features, but built like a tank. NEMA 4 rated for outdoor.
Safety, permits & NEC requirements
EV chargers draw high continuous loads — a 40A charger runs at full power for 6–10 hours straight, which is more demanding than almost any other residential circuit. The NEC has specific requirements for EV charging:
- NEC 625.41 — Breaker must be rated at 125% of charger's max draw (40A charger = 50A breaker). This is the #1 code violation we see on DIY installs.
- NEC 625.44 — GFCI protection required on all EV charging circuits. The charger's built-in GFCI counts, but the breaker must also be compatible.
- NEC 625.48 — A disconnect means must be within sight of the charger. Most wall-mounted chargers satisfy this with a plug, but hardwired units need a visible disconnect switch.
- Wire sizing — 6 AWG copper for 50A circuits under 50 ft. For runs over 50 ft, we upsize to 4 AWG to compensate for voltage drop (NEC 210.19(A) note 4).
