Use a shared nuetral or not? That is the question.


I have the electrical inspector telling me that I can either install the GFCI double pole breakers for these MWBC's or I can add an extra neutral wire so that each circuit will have its own and be on a single GFCI breaker. He says the #10 will take care of any voltage drop issue that I may have with the #12.

I don't want to ruffle his feathers but I would rather go with your suggestions!!! He also said it would possibly save me $$$$$$. I would think that an extra 220 feet of #10 wire would be more expensive than a GFCI dp breaker...maybe not.

Your explanation of a MWBC seems to make more sense to me now so that's the way I want to go. Thanks Stubbie.

Not to jump in on Stubbie, but as he is busy:

Your inspector is assuming you are going to use GFCI circuit breakers. He is thinking a double pole for a multi wire circuit or 2 single poles if you add a neutral. He is missing the GFCI receptacle option as Stubbie drew in his diagram. So, with the MWBC you have a choice between a 2 pole GFCI circuit breaker, or the GFCI receptacles. Cost is the consideration there.
