A inspector is wanting my contractor to put in a 3 pole 20 amp gfci breaker on a pizza dough mixer that has a cord that plugs into the wall. He won’t give the code he is calling out. Has anyone else ever heard of this before.

what code cycle.... It would be 210.8(B) for gfci

210.8(B)

Yes I have. I would assume all the appliances are GFI protected inside the kitchen.

Understand that it's the receptacle, not the load that requires the GFCI protection.

Good catch. I didn't add that part. ** All the appliances that are cord and plug to a receptacle **


The only ones that might have to be at the breaker, even without cord and plug are from 422.5. Or if you are in the NEC 2023 they are in a separate part of 210.8.

Dealing with this very problem today. We added a receptacle with a three phase GFCI module for a third pizza oven in a stack configuration and now we are having nuisance tripping issues due to what I suppose is the electronics current leakage on the ground from one of the other existing ovens in the stack.

Yep, anything with an inverter inside is going to be a headache for GFCIs.

Became a thing in the 2020 NEC. If you are in one of the 9 states that have not yet adopted the 2020+ Code, or one of the 4 states with only local adoption where it’s not there yet, then you don’t need it. Everywhere else, you do now.
