The answer to 'why is my EV charger tripping breaker' is that there are several common causes, including overloading the circuit, a faulty charger or wiring, or a problem with the electrical panel. The EV charger may be drawing more power than the circuit can handle, causing the breaker to trip as a safety measure.

Other potential issues include a short circuit in the charger or wiring, a ground fault, or a problem with the electrical panel itself. Symptoms may include the breaker tripping repeatedly, the charger not working properly, or signs of electrical issues like flickering lights or burning smells.
