Bob, I am having some trouble following your reasoning.
First of all, I've seen plenty of UL Standards, and they all reference the NEC. I am not aware of UL ever listing something that is inherently in conflict with the NEC.
110.3A says that equipment be 'suitable.' Now, perhaps I'm being too literal, but if the catalog and UL tag say "Commercial kitchen equipment," I would think it would be suitable for use in a commercial kitchen.
IF that same appliance had instructions that said 'no GFCI,' then 110.3B would be enforceable. Which, in this case, puts us squarely in conflict with the much newer 210.8 rule.
Sure looks like a code conflict to me.
