So it's a double pole breaker that is used like for 220 and the (shared) neutral makes both sides operate as 110.....Same as the new range and dryer circuits they added a neutral I'm guessing for the controls.

I somehow don't like this new rule and I'm not a fan of MWBC's anyway

Seems 2014 NEC states this and then what happens to the GFCI device do you still use that too?

Seems 2017 NEC will require whole dwelling to be AFCI

We use a combination afci/gfci breaker where required.

Only $35 a breaker, what a deal.

It actually costs me about a buck fifty less for afci/gfci then a straight afci. Can't figure that one out.

Last time I looked, and it was quite a while ago, a GFCI breaker was $27

Stop worrying about prices of breakers. In a couple more code cycles, you'll need to buy nothing but $250 GFCI/AFCI/MWCI/HOCI/TMCI/DYCI/CO2CI/CBCI breakers.

My guess is these CAF breakers are to protect us from faults in Chinese appliances, lamps, etc which are wired w/ 18 ga aluminum which is no doubt recycled ceiling grid from the world trade center

If you are building a flophouse kitchenette, maybe 6 circuits are too many, for an average American kitchen with about 8000 Watts of cooking toys on the countertops not so much...

Can you legally install 14 gauge wire in 20 amp rated outlet?

I'd spend more time on pricing the location of the main panel and maybe sub panel closer to densely wired areas.

Yup, just have to have the correct breaker for the wire size.

Why would there be a code specification for allowing use of a device that can handle more current than is being provided?

Plug a 20-amp load into a 20-a receptacle, protected by a 15-a OCD?

That wasn't the question. Next you'll be asking me for a code reference allowing a 15A breaker on 12 gauge wire.

Nope. I didn't make any claims. So it's not up to me to prove anything.
