I have direct connected refrigerated case inside grocery stores in aisle, check out areas. Would these require disconnect or not? If they do I am not sure which one applies NEC 2017 Article 430, 422 or 440?
 
Does this help?

440.1 Scope.
This article applies to electric motor-driven air-conditioning and refrigerating equipment and to the branch circuits and controllers for such equipment. It provides for the special considerations necessary for circuits supplying hermetic refrigerant motor-compressors and for any air-conditioning or refrigerating equipment that is supplied from a branch circuit that supplies a hermetic refrigerant motor-compressor.

440.3(B) Articles 422, 424, or 430.
The rules of Articles 422, 424, or 430, as applicable, shall apply to air-conditioning and refrigerating equipment that does not incorporate a hermetic refrigerant motor-compressor. This equipment includes devices that employ refrigeration compressors driven by conventional motors, furnaces with air-conditioning evaporator coils instal⁠led, fan-coil units, remote forced air-cooled condensers, remote commercial refrigerators, and so forth.

Doesn't just about everything require a disconnect? The more detailed question is whether that disconnect can be remote, like at the breaker panel with a breaker lock.

I've never seen a local disconnect on a grocery refer case.
