See Table 210.21(B)(3)
This only applies to MORE than one receptacle.... I can legally install a 20 amp single round receptacle on a 15 amp branch circuit.

Yes, you can do that in the US as long as receptacles is plural. Interesting that this is not the case in Canada.

I agree. And it is covered in the NEC. I'm a residential electrician.. i just love this forum for more interesting pick up knowledge to take in the field. As the books states: It all just a practice. Meaning electrical is a learning trade, whether your a residential electrician.. or a master electrician! Just means you proceeded on to taking the additional test to obtaining the masters card(thats not towards u Andrew..just saying.)
