    "Sinks" without a water supply drive GFCI requirements? I wouldn't ask for it at a hub drain or floor drain, but floor sinks are not really addressed or exempted.....?

    You come up with unusual questions. A mop sink has water supplied. A janitors sink has a water supply. If there is no water supply, is it really a sink?.....or just a drain.....you know, for old paint and stuff.

    Why then are floor sinks required beneath equipment in commercial kitchens?

    A floor sink that’s not really a sink. What’s next ... a water closet that’s not really a closet?

    If they were usual, then I wouldn't have a question.....is it the basin or the supply or the drain that drives the GFCI requirement? I think not the supply or we would be requiring them within 6' of hose bibbs...2023 NFPA 70 here we come...

    They handle tailpieces and condensate. And by the way, all receptacles in a commercial kitchen have GFCI protection.

    What about floor sinks beneath refrigerated displays in grocery stores? It is called a floor sink and receptacles are not required to be protected with GFCI on a sales floor.

    Not a "commercial kitchen" concession counter. Microwaves do not count as cooking per NFPA...That is a whole nother argument....

    I think that it is a stretch to require GFCI for a receptacle within six feet of a floor sink. However, considering the minor expense involved I wouldn't argue against that. I would not write that correction.

    floor sinks generally are not readily accessible in most cases - also they generally are equipment specific and not designed for general floor drainage - i.e. tilt kettle. And to be a little bit more specific, our Health department will not require floor sinks to be connected to a grease traps whereas floor drains do..........

    We see lots of floor sinks, but very few floor drains in our kitchens.

    So 3 compartment sinks and dishwashers and other equipment that will have grease in the water that are being drained via air gap into a floor sink would not go to a grease trap in your jurisdiction?
