Any guidance available on how many outlets (receptacles) should be placed on a small appliance branch circuit? How about on a general purpose branch circuit?

Re: # of receptacles

Per the NEC there is no limit in residential.

As far as how many should be on a circuit, this is kind of a judgment and common sense call.

Re: # of receptacles

You are going to get all kinds of different answers with this question.

We typically put 3-4 receptacles on a small appliance branch circut.
We keep the dining and nook on a seperate circut.
We also put the frig on it's own circut.

As for the general purpose branch circuts, we try to limit these to 8-10. Worst case we would go 12.

These are conservative figures, and you could put more on either.

Re: # of receptacles

If cost isn't a factor and they serve counter space i would do no more than 4,if its picking up a few that are required by code but not likely to be used i might go 6,meaning 3 unlikely and 3 that will be used.This is just my opinion not NEC
Other lighting circuits something like 10 to a max of 14 try to keep under 13.Do not worry about switches only duplex or light fixture.If they are multi lamps consider the watts and lower that number

As far as a dwelling goes the NEC does not have any requirements. But if this is commercial then the 180 VA per strap applies. See 220.3(B) 1-11

I agree with Luke

NEC doesnt restrict # of outlets in res, just 2 SA circuits and 3watts per SF, but I have never seen a house done this way.

Our county does restrict outlets to 2 per circuit in kitchen and 10 in rest of house.

No (NEC) limit in residential other than common sense to avoid overload trips.

However, some places may have local amendments for the kitchen area that require a dedicated 20A branch for areas intended for a microwave (ex. Palm Beach county in FL has a requirement like this). Hard to tell where someone might put one on the countertop, but if an over the stove unit is planned, its something to watch out for.

That seems like a strange requirement, considering the fact that I've never seen a residential microwave with a 20 amp cord end on it.

I thought the same thing right off the bat, then I checked my over the stove hood microwave.

The input power is 1800 watts at 120 volt.

That being the case 210.23(A)(2) would require it to have a dedicated line.

If it was placed on the counter it would be on the edge of 210.23(A)(1)

That FL requirement is almost redundant. :p

Re: # of receptacles

Actually I recalled it wrong, the PBC amendments are here:

http://www.iaeifl.org/palmbeach/pdf/99nec.pdf

It looks like the microwave is just required to be on its own branch - they didn't say 20A specifically (although that's what I'd put one on since some are pretty high powered and could run into the continuous use issues otherwise).
