George that is twice today I have been called Mr.
Please call me Bob
First I did not say it was a great idea but lets look some of 210.21(B)
(1) Single Receptacle on an Individual Branch Circuit. A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit.
Notice they did not say the same rating as the branch circuit or the values in Table 210.21(B)(3).
210.21(B)(3) Receptacle Ratings. Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in Table 210.21(B)(3), or where larger than 50 amperes, the receptacle rating shall not be less than the branch-circuit rating.
IMO it is clear the requirements for single receptacles have nothing to do with Table 210.21(B)(3).
IMO single receptacles and multiple receptacles rated over 50 amps may be supplied with branch circuits rated lower than the receptacle.
I would have to ask what code section prohibits using a single 30 amp receptacle on a 15 amp circuit.
An engineer once wrote in asking if he could feed a 200 amp pin and sleeve receptacle with a 90 amp branch circuit.
No one could find a code section preventing that.
