The Gen 3 Wall Connector delivers up to 11.5 kW (48A) — roughly 44 miles of range per hour on a Model Y or Model 3. Beyond raw speed, it's the only home charger that ships with native Tesla One app integration, automatic firmware updates, and built-in Power Share load management for homes installing more than one unit.
- Up to 48A / 11.5 kW output (hardwired only)
- NACS / J3400 connector — works with every Tesla and, with an adapter, most modern EVs
- 24-ft cable standard
- Indoor / outdoor rated (NEMA Type 3R)
- 4-year residential warranty
Electrical requirements
The Wall Connector is hardwire only — there is no plug version. Output is set in the Tesla One app to match the installed breaker.
| Breaker | Wire (Cu) | Continuous output | Miles / hr (Model Y) |
|---|---|---|---|
| 60A | #6 | 48A · 11.5 kW | ~44 |
| 50A | #8 | 40A · 9.6 kW | ~37 |
| 40A | #8 | 32A · 7.7 kW | ~30 |
| 30A | #10 | 24A · 5.7 kW | ~22 |
Run lengths over ~75 ft typically require upsizing one wire gauge to keep voltage drop under 3%. We size every run during the site assessment.
Wi-Fi & app setup
Wi-Fi is required to commission the unit. After power-up, the connector broadcasts a setup network the Tesla One app joins; from there you select your home 2.4 GHz SSID, set the maximum breaker rating, and apply the latest firmware. The unit will continue charging if Wi-Fi later drops, but firmware updates, remote diagnostics, and Power Share grouping all need an internet connection.
Step-by-step installation
- Site assessment. Panel capacity, breaker space, and run distance from panel to parking spot.
- Load calculation & sizing. NEC 220.83 calc to confirm the existing service can carry the added continuous load.
- Permit. We pull the electrical permit with Kennewick, Richland, Pasco, or West Richland.
- Circuit run. Dedicated 2-pole breaker, conduit or NM-B per location, properly bonded ground.
- Wall Connector mount. Hardwire termination torqued to Tesla spec (24 in-lb).
- Commission. Wi-Fi, breaker rating, firmware, label, and a test charge session.
- Inspection. City inspector signs off — required for insurance coverage and warranty.
Cost in the Tri-Cities
Typical all-in residential installs in Kennewick, Richland, and Pasco land between $750 and $1,800. The big variables are the conduit run length, whether the panel needs a sub-breaker upgrade, and whether the route crosses finished walls. We quote flat after the on-site assessment — no surprise change orders.
Frequently asked questions
- Does it charge non-Tesla EVs?
- Yes — the NACS connector works with every Tesla, and most modern EVs charge at full rate via the appropriate adapter.
- Plug-in version?
- Tesla's Wall Connector is hardwire only. If you need a plug-in unit, the Tesla Universal Mobile Connector covers NEMA 14-50 at 32A / 7.7 kW.
- Can I install it outside?
- Yes — NEMA Type 3R rated for outdoor installation. We add an outdoor-rated disconnect when local code requires it.
- How long does the install take?
- Most jobs are a single 3–5 hour visit. Panel upgrades or long underground runs add a day.
