Just curious if anyone connects the dishwasher and garbage disposal to one of the two 20A branch circuits required in the kitchen or is a dedicated circuit ran for these appliances?

Re: appliance brance circuits
The 20A circuits are small appliance branch circuits, its laid out in section 210.52(B)(2) and the title is No Other Outlets.
See the article 100 definition of what an outlet is.

Re: appliance brance circuits
Depending on your AHJ you may have to run a separate circuit for each motor (i.e.- one circuit for the DW and one circuit for the DW). For more on that look at
430.53(A) Several Motors or Loads on One Branch Circuit: Not Over 1 Horsepower.
In summary you can't put them on the SAC as mentioned above, and you will have to run one or two dedicated circuits to cover the DW & Disp depending on your AHJ. You are permitted to put the refer on the SAC but it can be a trade practice to put it ahead of the GFCI protection.

Re: appliance brance circuits
I guess I always looked at is those to loads are not likely to be used at the same time. You scape all the stuff in the disposal as you are loading the dishwasher. When you get it all done you run the disposal and as you wipe down the counter turn on the dishwasher.
(that's how my wife taught me) Go ahead and laugh i know you guys do dishes too. My point is that since they don't operate at the same time I use 1 circuit and split it up under the sink. Could you make the point that it is 2 motor loads and all that yes, but even the most stringent inspector should bend to the logic that you don't use them at the same time.

Re: appliance brance circuits
I'm curious, when we're talking about the dishwasher and disposal, what are the amperages, generally speaking?

Re: appliance brance circuits
1 hp disposal at about 10 amps and a Bosch dishwasher at 12 amps on one circuit? Bad electrician!

Re: appliance brance circuits
My Maytag dishwasher is 6.5 amps.
My Insinkerator 3/4 HP is 6.0 amps.
Both do the job. I guess I should be lucky I don't have a Bosch yet or a 1-HP.

Re: appliance brance circuits
210.23 Permissible Loads.
(A)(2) Permits the multiple loads to not exceed 50% of the branch circuit rating.
I have seen the dishwasher and the disposal range in size. If you know the ratings of the equipment before you pull the circuits, you can determine if you need two circuits, if you do not know the ratings, you may be better off running two circuits.
Why would a two pole breaker be required?
... Or you can follow 210.19 (A)(4) exception No. 1. Run a 30 amp circuit and tap them under the sink.

Pierre, if a multiwire branch circuit such as this would be supplies a common yoke both ungrounded conductors must be broken at the same time.
