Am I reading Article 210.21 (B) (1) properly?
If an receptacle is the only one on the circuit, the branch circuit rating may be less than the receptacle? For example, according to this article, it would be allowable to put a NEMA 14-50R on a circuit with a 30A double pole breaker and wired with 10-3 wire? Or to place a NEMA 5-20R on a circuit with a 15A single pole breaker and wired with 14-2 wire?
I'm surprised with this - I always figured that the receptacle rating must match the circuit, with the exception of multiple 5-15R on 20A circuits and
14-50R on a 40A circuit when feeding a range.Matthew
