Do you have available breaker space? Your electrical panel needs an open slot for a two-pole breaker. If not, your electrician may need to consolidate existing circuits or, in some cases, install a sub-panel.
Consider future needs: If you plan on getting another EV down the line, mention this to your electrician. Tesla Wall Connectors support power-sharing, which allows multiple Wall Connectors to intelligently distribute power from a single circuit.
Sub-heading 1.2: Choosing the Right Location
Proximity to your vehicle's charge port: The ideal location is usually on the side of your garage or parking space directly adjacent to where your Tesla's charge port will be when parked. The Wall Connector comes with a 24-foot cable, offering good flexibility.
Proximity to your electrical panel: The shorter the distance between the Wall Connector and your electrical panel, the less expensive and complex the wiring run will be.
Mounting height: Tesla recommends a mounting height of approximately 59 inches (1.5 meters) above the ground, with at least 8 inches of clearance around the unit for cable management. The Wall Connector is designed for both indoor and outdoor installation.
Sub-heading 1.3: Understanding Permits and Regulations
Local codes are key: EV charger installations are regulated by local building and electrical codes. It's essential to obtain any necessary permits before starting the installation. An experienced electrician will be familiar with these requirements and can help you navigate the permitting process, ensuring your installation passes inspection. Skipping this step can lead to fines or issues with insurance.
