We are doing kitchen reno. We had to replace the main breaker panel. Local code requires we use arc fault breakers. This is not an issue for most of the project, however, the inspector is insisting that we have combo arc fault with dual function of GFCI. The Arc faults work fine, however the GFCI keep tripping.
I explained to the inspector that this is a shared natural circuit and the GFCI will trip as the current coming back will not match what is going out. I will install GFCI at all the outlets to cover that requirement, however, he is insisting the breaker needs to be GFCI.
Can anyone point me to somewhere in the NEC where I can prove to him that having the GFCI at the outlet is legit and for all the shared natural circuits we will use combo arc fault only, not dual function. I know some of you will tell me to run new wires for the MWBC so they all have their own neutral.
Any other suggestions ?
