avt gas circuit breakers Charging

If we use a 100A circuit breaker for 30A circuit, it wont protect the circuit from fault currents and may burn and damage the device as more than 30 amperes current won't trip the circuit breaker. In short, we must use the proper size of circuit breaker according to the device i.e. CB current should not be lower nor highest but 125% of ...

  • Tesla Charger at 30 Amps — Tesla Forums

    For example with a 30A breaker, you would set the HPWC so that it only tells the car to accept 24A. IMPORTANT: A 30A breaker does not mean that you can charge your car at 30A. By design the amount of continuous power that can be pulled is 80% of the rated breaker. So a 40A breaker can only pull 32A on a continuous basis.
