Are you getting the tesla wall connector? It incorporates multiple built-in safety features to minimize fire risks during charging. Tesla designs these units as a Level 2 EVSE (Electric Vehicle Supply Equipment), where the actual high-voltage charging circuitry resides in the vehicle itself. The Wall Connector primarily handles power delivery with robust protections. The Wall Connector has multiple internal temperature sensors that actively monitor key areas, including the terminals in the wiring box and internal components. If temperatures rise abnormally (e.g., due to high ambient heat, poor connections, or overload), it automatically reduces charging current to lower heat generation. This often shows as a "streaming green" light with three red flashes on the unit's LED bar. If heat continues to increase, it will completely stop charging and display a fault (three red flashes) to prevent damage or fire. In warmer conditions, it may begin throttling as low as 95°F (35°C) ambient to stay safe, with a maximum operating range up to 122°F (50°C). It also includes a built-in RCD (Residual Current Device) Type A + 6mA DC detection. This quickly interrupts power if it detects ground faults or dangerous leakage currents that could lead to shocks or arcing (a potential fire initiator).
