What You'll Need
- Tesla Universal Wall Connector
- 240V circuit breaker (60A recommended for 48A charging)
- Appropriate gauge wire (6 AWG for 48A)
- Screwdriver and wire strippers
- Voltage tester
- Tesla app on smartphone
- WiFi network credentials
Important Safety Notice
Warning: This installation requires working with high-voltage electricity. Many jurisdictions require a licensed electrician and permit. Check local codes before proceeding.
Step-by-Step Installation
- Turn off power: Switch off the main breaker and the dedicated circuit breaker for the installation location.
- Mount the backplate: Position the Wall Connector backplate at least 18 inches from the ground. Mark mounting holes and drill.
- Run the wiring: Route the 240V wiring from your electrical panel to the Wall Connector location through appropriate conduit.
- Connect the wires: Open the Wall Connector cover. Connect the two hot wires to L1 and L2 terminals, and the ground wire to the ground terminal.
- Set the amperage: Use the rotary dial inside the unit to set maximum amperage based on your circuit capacity (breaker should be 125% of set amperage).
- Secure the cover: Replace the Wall Connector faceplate and tighten all screws.
- Restore power: Turn on the circuit breaker. The Wall Connector LED should illuminate.
- Configure WiFi: Open the Tesla app, go to "Charging" > "Wall Connector" and follow prompts to connect to your WiFi network.
- Test charging: Plug in your vehicle and verify charging begins. The LED will pulse green during charging.
