What is the continuous load rule for EV charging?
Answer: Circuit breaker must be rated at 125% of maximum load
EV charging is a continuous load requiring 125% circuit rating.
What is a CCS connector?
Answer: Combined Charging System adding DC pins to J1772 for fast charging
CCS combines J1772 AC connector with DC fast charging pins.
What is load management for multiple EV chargers?
Answer: Distributing available capacity among chargers to stay within limits
