Re: Outlets Per Breaker

So after all this, How many receptacles on a 20 amp circuit? I say 10. You can only load the 20 amp circuit to 16 amps 16 x 120 = 1920watts Div. by 180watts = 10.66666.. I love the way this thread changed and became so long

John, you can load a 20 amp circuit to 20 amps for 179 minutes at a time.

Re: Outlets Per Breaker

I see this somewhat frequently. My assumption is a misunderstanding of 210.23(A)(1).

And of all the griping I do about CMP 2 and article 210, that section is (in my opinion) about the best written out of the entire article. Not that's saying much. :D

Edit: I had to add an obligatory disparaging remark.

If you feed the fridge with a single 20 amp circuit and install a single raceptacle rated the same as the circuit, then all is well with 210.52(B)(1) exception 2. :D

Now install a duplex receptacle and you just changed the circuit to a SA circuit. And still all is well because 210.52(B)(1) allows it to feed the "receptacle outlets for refrigeration equipment." There would still be no violation unless the rating of the circuit was 15 amps instead of 20. ;)

Re: Outlets Per Breaker

Why cant the frig be on a duplex ?When it becomes a duplex it no longer is a dedicted circuit,it becomes a SA.
And as long as it does not serve the counter then no gfci.Where is the problem ?

Re: Outlets Per Breaker

This whole article is screwy,table
210 B 3 says a 20 amp circuit can use a 15 or a 20 amp receptacle outlet but 210 20 B 1 says a single device has to match ampacity of the branch circuit :eek:

Do you mean 210.21(B)(1)? If so, it doesnot say "single device", it says "single receptacle" That's the difference. I don't see anywhere the NEC uses the term "device" in relation to this topic that would lead someone to reason that "receptacle" referred to "per yoke". I think 210.21(B)(3) clearly allows a 15A duplex to be installed on a 20A circuit for the fridge. A duplex is clearly more than one receptacle.

Re: Outlets Per Breaker

it does say receptacle not device but the whole senario is screwed upYou can put a 15 amp duplex on a individual 20 amp circuit cause it is a duplex but a single 20 has to be on a 20 amp individual circuit because it has to match ampacities :roll:

You're right on that count. I hope the "210.23" issue is clear in most minds. But I contend this is a violation of 210.52(B)(2), despite being compliant with 210.23.

So who will take up the gauntlet of showing me to the crow? :D

I think I got lost in all the dust. What exactly is the question?

Re: Outlets Per Breaker

Where am I technically incorrect in my interpretation that installing a duplex receptacle behind a fridge is a violation of 210.52(B)(2)?

Re: Outlets Per Breaker

Now with that same duplex receptacle can we plug in a freezer AND a refigerator ??

Yes, that would be allowed according to the article .

Re: Outlets Per Breaker

George, if you install an individual 20 amp branch circuit for a fridge and you use a duplex receptacle I guess it now becomes a small appliance branch circuit. No problemo! The SA circuit is specifically permitted to serve refrigeration equipment in 210.52 B 1
