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.
So you are saying you could put a 50 amp single receptacle on a 15 amp branch circuit?????Yes, 210.21 (B) (1) does state it is possible. BUT it is only one section of Part II, Branch circuit ratings.
Another section of that same part (Part II, branch circuit ratings), section 210.23, states that in no case shall the load exceed the branch-circuit ampere rating.
By installing that 20 amp receptacle, you would be allowing for a potential of a 20 amp load on a 15 amp individual branch circuit, a clear violation of 210.23.
So, in theory, if you just look at section 210.21 (B) (1), you could put the 20 amp receptacle on the 15 amp circuit. But when you review the entire part of article 210, you can easily see where this would be a violation if installed.
You have to take the sections in the context of the entire Parts of the articles.
