I think Rob's point was that you can put a 20A receptacle on a 15A individual branch circuit, per 210.21(B)(1).

I think it is funny that the NEC "allows" a single 20 amp receptacle on a 15 amp individual branch circuit in 210.21(B)(1) but then turns around and prohibits any receptacle greater than 15 amps on a 15 amp branch circuit supplying two or more receptacles in 210.21(B)(3).

I assume that when I see a single 20 amp receptacle on an individual branch circuit, I will have a 20 amp branch circuit. But then again, I have learned that everyone doesn't design, wire, and install the same way. :rant:

I think for the most part you will not see this as a standard installation practice even though it's permitted by the NEC. What you will see quite often is a 40 amp range circuit with a 50 amp single receptacle and a 50 amp range cord since there really is no standard 40 amp range cord.
