I have an 1800W (input) microwave connected to a 15A duplex receptacle fed from a 20A circuit breaker. My understanding is 210.21(B)(3) is what allows a 15A receptacle to be fed from a 20A circuit breaker.
Since the receptacle is a duplex, it is my understanding that this is NOT an individual branch circuit. Therefore, applying 210.21(B)(2), it seems that the maximum load the presented to the receptacle should be limited to 12A (1440W).
Is this a violation, or am I misunderstanding?
