A 40-ampere branch circuit can supply either 40- or 50-ampere receptacles. While a 50-ampere branch circuit can supply 50-ampere receptacles, it cannot supply 40-ampere receptacles. For branch circuits that are larger than 50 amperes, the receptacle rating must not be less than the rating of the branch circuit.
