Kitchen GFI receptacle circuits

[alvez]

Has anyone taken a 12-3 w/gnd for the two required kitchen utilitiy circuits and protected them on a
double pole 20 amp. GFI circuit breaker. I'm suspicious
it won't work since the GFI reads the differential between
hot and neutral! Am I right?

It will work as long as all three circuit conductors (White, Black, Red) are terminated to the two pole GFCI breaker.

But of course a problem on one circuit will take out both circuits.

A double pole GFCI breaker will look at the current on both hots and the neutral. Without leakage or a fault this current will always sum to zero, so the two pole breaker works for both 240 volt loads and 120 volt loads as well as any combintation of the two.

Although it will work with a 2P CB, is this more cost effective than 2 GFCI receptacles? Not to mention the downside of having two circuits trip at once.

I suspect it is to late now to discuss the down side to what you are doing but it will work.

You forgot to add that if you went this route then 12/3 would NOT work. it would have to be 2 x 12/2

BEFORE Anyone comments; I take that all back. A long day with little sleep tonight. Sorry

Why is that? If you use two sp breakers with a MWBC , then you could hook one GFI receptacle at that point and run a 12/2 to the next box hooking the neutrals ahead of the GFI. It will work.

Yup! and if you read my "edit" closely you will see that I can't even tell the difference between "tonight" and "last night" right now. Told you I was tired.

Pete, thanks for leaving the text there, and making your added edit clear.

just out of curiosity, is there any advantage to this setup, other than a customer not wanting to look at gfis?

The customer may get some extra exercise

If the panel is anywhere but in the kitchen.... I can't ever remember resetting a gfi in my own home... just trouble calls, I just don't understand why people cannot understand how to reset a breaker or a gfi? I clearly explain to my customers how to do it before I leave....
