I had an interesting conversation with a Leviton rep. He said there is no difference in the internal architecture between a 15A and 20A receptacles other than the shape and that the 15A part is built to carry the 20A load. He said that goes for all manufacturers and is an industry standard for their standard receptacles *of course they offer heavy duty versions). So maybe this is why the NEC allows 15A receptacles on a 20A circuit.
I think you'll find that most electricians use 15 amp outlets on 20 amp circuits with 12 gauge wiring. It's done all the time. If using 14 wire you need a 15 amp breaker.
I agree. It's pretty much standard to wire lighting circuits with 14 ga. wire and outlet circuits with 12 ga. wire. When we built our current house we specified no wiring smaller than 12 ga. We didn't specify that the outlets should be 20 amp so the contractor installed 15 amp ones.
Having said that 12 ga. wire is rated for 18 amps on a continuous basis.
