MWBC on 2 Gfci's


Is there a creative way of making 2 -120v gfci receptacles work off a 12-3 mwbc which feeds 2 - 120v circuits without 1 or the other tripping ?

Nope! Unless you install GFCI receps in place of all receps on the circuit.

Are the two GFIs in the same box or different ones, and are there GFI protected circuits fed from one or both GFIs?

Basically, you feed one of the GFIs with black and white of the 12/3, and the other with red and white.

If there are receptacles downstream from either GFI, they need to be on separate 12/2s, each one connected to the load side of each GFI.

You can't use 12/3 on the load side of a GFI; the neutrals cannot be shared.

Yes, you just pigtail the neutral before splitting into two circuits.

Should have looked at the posters name. I think we are being trolled.

I wondered the same thing.

No problem. You use white and black on one receptacle and red and white on the other receptacle. You can not do split wired receptacles.
