    Shared neutral ~ 1 GFI circuit and one non
    Hello, I have an existing 12/3 NMB in a jbox in the kitchen. Can I use one circuit for a GFCI Countertop circuit and one circuit for a dedicated microwave circuit that does not need GFI protection and share the neutral? Thank you!

    At the first box you will need to split off to two separate 12/2 cables.
    It gets a bit trickier if you want to load out to other receptacles from the GFI.
