12/3 feeding two circuits with two GFIs

How would you wire this? This a kitchen and it needs two gfi's as there's two circuits but it's fed with just a 12/3. In this first box the black is feeding the first cir. and some other outlets. The red is tied to an other 12/3 that is feeding the second gfi in an other box. There's a dishwasher that needs to be on the line side from the second box as well as other outlets. How would you do this?

Shared neutral, 2-pole breaker in panel, wire like any other ckt. for a kitchen. My boss is a big fan of doing this, I'm not. The 3-wire that jumps off the original 12-3 home run to the dishwasher, you can't line/load that wire until you transition to 12-2.

Is this a side job or for work?

This is for work. My JW originally changed one of the double duplexes to two gfi's but that didn't work as the load wasn't were it was supposed to be. I told him that I wasn't exactly sure what was going on in the boxes and that I was a little confused. He told he to do it any way. We I thought I had it figured out and then he comes in and says move I'll do it my self. I was asking him where the neutral should be going and that's when he got all in a tizzy. We when I stepped away from the box I lost track of what was connected to what and he got even more bent out of shape cause I "tore stuff apart with out remembering what went where". So I'm trying to be a good apprentice and come up with solutions to this problem. The kitchen is a mess btw.

There is no other way if it is a 12/3....well unless you just amalgamate it all onto one circuit....Your GFCIs will notice the imbalance right away. Your journeyman sounds like a real idiot.

That's what I was thinking but hey I'm just an apprentice and don't know anything.

Oh he's something alright. If you ask him he's gods gift to the trade. And he makes his views very well known.

Box #1.

Connect both 12/3 whites and leave a pigtail.
Connect the 12/3 red to the outgoing 12/3 red. Cap the black
Connect the incoming 12/3 black and the white pigtail to line side of GFCI
Connect any outgoing protected load wires connected to load side.

Box #2

Cap the 12/3 black
Connect the 12/3 red and the dishwasher black to the line side of the gfci
Connect the 12/3 white and the dishwasher white to the line side of the gfci
Connect any outgoing protected load wires connected to load side.

You cannot wire the dishwasher to the kitchen counter receptacles.
Well,..... there's that :)

But he asked how to accomplish a specific task aso I didn't want to complicate it any further.

And, you can do it. Just not legally. :thumbsup:

He's "god" and I'm an apprentice.

Does it make a difference if this is not a new build or even a remodel but just adding gfi protection to the kitchen?
If the wiring is run (existing) then adding the gfci can only help so it would not be a violation.
