Dedicated circuit for dishwasher or garbage disposal

Under the strict definitions you just quoted there can be no dedicated circuit for a microwave, a dishwasher, a garbage disposal or a range or a hood. Because under your definitions there is no place to put them in a kitchen as all wall outlets are taken, all counter spaces are taken... only switches and luminaries are left.
Thus, the fact there is an exception for fifteen amp feeders to dedicated appliances does not count.
and the dedicated circuits does not count.
because all counter and wall circuits must be part of the small appliance circuits and can have no other outlets, if they supply a wall or counter outlet in the specific areas.

I never said there can't be circuits for those things. I'm showing they can't be on the two SABCs.
 
And I have stated that these circuits are not on the two sabc circuits but are extra... however, the statements I am getting back are that because there is an outlet at the counter this then becomes an sabc... even though there are already the two..actually three, sabc circuits.
Thus, I am wondering how to supply this without a very expensive and hard to find deadfront gfci, while still meeting the requirements of a switch above the counter for the operation of the disposal, and the requirement for gfci as both are less than thirty amps and in an area covered by the rules for gfci, and also meeting the requirement of both the gfci being readily accessible and the outlet for the garbage disposal and the dishwasher being accessible.
Because I am reading these pages and either the equipment is considered part of the small appliances or it is not allowed... due to the strictness of the rules for the circuits and how they define all the outlets to the counter and walls, and the no other outlets.
my own definition of the no other outlets rule would be the rule for bathrooms... that no outlets in other rooms are allowed, only in those rooms listed as part of the defined space..the kitchen, the dining room, etc.
thus, the single outlet above the counter feeding the dedicated outlet for the dishwasher and the garbage disposal would be allowed, as they are all in the kitchen space.
this would be the same as allowing an outlet supplying the iron to be part of the washing machine circuit in the laundry area, but the washer circuit cannot supply outlets outside of the laundry area.
But, based upon the answers in this thread, the actual interpretation is stricter for how outlets in a kitchen are actually classed.
Thus my confusion, and my searching for clarification.
 
Adam, I just got up so bear with me.

You are using the 2017, correct?

It seems that the exception is the basis for what you want to do or is there something else?

This is the rewritten exception as adopted for the 2017:

Exception No. 2: In addition to the required receptacles specified by 210.52, a receptacle outlet to serve a specific appliance shall be permitted to be supplied from an individual branch circuit rated 15 amperes or greater.

What part of this makes you think it allows a counter top SABC receptacle to share a circuit with a DW or disposal?
 
Because there is nothing in exception two to stop one from having in the following order...
afci breaker of 15 or 20 amps.. feeder.. gfci outlet above worktop.. 20 amp double pole switch.. garbage disposal under sink cabinet

or same gfci outlet above sink feeding both the outlet for the disposal and the outlet for the dishwasher.

with no extra outlets on it.

As long as this circuit is not one of the two or more SABC circuits required elsewhere for the kitchen.

this is in effect a dedicated circuit for the dishwasher and garbage disposal. Now has both AFCI and GFCI protection, can be trouble shot, can have both the dishwasher and garbage disposal turned off quickly by tripping the gfci in the kitchen, before turning power off at the breaker panel, should you have a sudden water problem in the kitchen,

and is easier to find the parts for than using a deadfront gfci.

But is not allowed according to many. So, is the circuit wrong or is the code wrong or is the perception of the code wrong? Is the exception right there but we do not see it as such because the person is adding a gfci outlet to the circuit rather than wiring directly under the cabinet instead from the breaker, which is thirty feet away?
 
It is pretty clear that a counter top SABC receptacle cannot also feed an appliance.

The exception merely changed and says additional 15A or more individual circuits for specific appliances are now allowed in the defined SABC areas. It used to be for refrigeration equipment only.

I can now run a individual/dedicated 15A circuit, say for a microwave, for a specific appliance and install that receptacle on a wall or countertop as long I have the met the SABC requirements.

That can be installed above counter top and feed an appliance, but not a GFCI receptacle.

You're saying this can't feed a receptacle? That's the only time I've ever seen them used. Do you have a Code reference handy? I've never installed one myself.

Leviton even says: "Blank Face GFCIs can be used ... indoors to provide downstream protection to outdoor outlets."

No, I am not saying that at all. I am saying that if that was a GFCI receptacle instead of a switch, you could not use that receptacle circuit to feed a DW or disposal. We are talking about counter tops here.
 
I misread your post. I thought you were saying it could feed an appliance but it couldn't feed a receptacle. I see how to read it now.

My post was in reply to someone who said they were expensive and hard-to-find.

I make no judgment whether it is the best way to do the job.

The changing of the exception in the 2014 just allows use to install individual 15A circuits to specific/dedicated appliances in the SABC definited areas beyond just refrigeration equipment.

Under the 2014 and earlier editions, one could not.
