    A run in 1" plastic conduit from the main panel to power a stove and a microwave. So individual conductors will be used.

    Stove is on 50A breaker with #8 wire, microwave on 20A breaker with #12 wire.

    The 1" plastic conduit will be run to a junction box and will contain four #8 conductors(red,black,white ,green) and one #12 conductor(blue).

    Question is....in the junction box can the #8 neutral and ground be connected to #12 neutral and groung conductors for the run to the microwave?

    Kind of like the diagram. Although I did not show the red and black for the stove continuing because it was getting crowded in the drawing.

    I guess this post was before a answer was given on the other forum.

    "No, you cannot do that."

    The logical answer would be that there is NOTHING on either appliance that "needs" a #8 neutral, and the ground in a JB is often a common for everything in it.

    I think that a GFCI will be required for your install.

    If you start sharing Neutrals strange things can happen.


    Good Luck.

    Maybe if it is going through a GFCI or you overload it.
