In the kictern you got to run two small appliance 20 amp circuit, this is usually done with 12-3 wire. My question is: Since the last recpicle in the circuit dead end, that one and one before can be run with 12-2. Am I right?

Johnnie,
You are incredibly right. You are so absolutely correct, it is incredible.
You could run two 12-2s all the way to the panel or a single 12-3 from the panel to the kitchen and use the red/white and black/white combo for each receptacle. And, for the last one on the chain, just use 12-2. But be nice and label or red-tape it if the black wire is really the red circuit.
Don't forget about the GFCIs near the sink.

*Yes, you could go with 12-2 for the last one. But the way I'd do it is to use 2-gang boxes for all the kitchen counter locations and have four outlets, two on each circuit, in each box. You're going to live there for a long time, so you'll probably collect a bunch of electrical kitchen gadgets. Now is the easy time to put in plenty of plugs.-- J.S.
*Now you only need to know the rest of the details to do this right.1) how do you wire the CFGI's?2) how do you wire the recepts?two NM cables are easier to do and perhaps safer.I do like the idea of 4 recpts at each location.
*Johnnie, Running those two circuits off of a 12/3 cable is a BAD idea. If you don't get the two hot legs on different phases at the circuit breaker box, you could be running 40 amps through an unprotected neutral wire. This is not a do-it-yourselfer type hookup and I can see where you could have some confusion as to how to hook it up properly. Use the two cables. You aren't saving yourself any time or money anyway. I think they should ban this practice from residential wiring. I assume you have to use GFCI's if it is being inspected??? If so, it won't work.
*I agree with G. LaLonde. Not a good practice. I am thinking there would actually be more waste simply because 12/3 is far more expensive than 12/2 and you probably wouldnt use it anywhere else in your home.
