In reading article 210.21(B)(1) "A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit.

I would like to get some sort of a defintion to "single receptacle". Is (1)duplex receptacle a single receptacle?

My view it is not a single receptacle, am I alone here?

See 100(I) Receptacle. Duplex is a multiple receptacle not a single.

Receptacle. A receptacle is a contact device installed at the outlet for the connection of an attachment plug. A single receptacle is a single contact device with no other contact device on the same yoke. A multiple receptacle is two or more contact devices on the same yoke.
 
Way back when I did residential, a customer doing a full dormer with 4 bedrooms wanted an extra - an a/c outlet in each bedroom. At the time the shop priced each new 20a circuit and a/c receptacle at about 275.00, and the customer was already overbudget, I suggested 2 20a circuits each with 2 duplexs located under two bedroom windows to replace 4nof the already planned 15a convenience circuit receptacles.

Customer agreed and the boss went ballistic claiming you can't put a 15a duplexs on a 20a circuit, nor can you put 2 window shakers on one 20a circuit, etc...

In the end I was right, he was wrong, but it still din't get me nowhere... :grin:

440.62 C would you combine the load to figure 50% of the branch circuit rating

So the boss wanted you to install 20a duplexes and GFIs on the SABCs as well?
 
Some people get set in their ways, and expect everyone else to follow. His reasoning (feeding both circuits with a MWBC to boot) - impossible to "switch" to 220v (Like that would happen in a 10 x 12 bedroom) and he thought 6000 btu a/c's still consumed 14 amps.

As for 20a duplexes on the SABCs, no... however any customer who wanted anything other than a brown duplex with a white metal coverplate had to pay an extra- even though at the time NOBODY was installing brown anymore, and ivory or white devices were the norm.
