Class II Div 2 Equipment
Class II Div 2 Equipment
(OP)
We are struggling to find specific requirements for equipment that must be installed in a Class II Division 2 Group F location. From the NEC description it would appear that NEMA 12 is sufficient but that doesn't give us a lot of confidence that we're 100% covered. Is there any clear guidance out there for specific equipment ratings and installation practices required for Class II Division 2?

"Where specifically permitted in Articles 501 through 503, general-purpose equipment or equipment in general-purpose enclosures shall be permitted to be installed in Division 2 locations if the equipment does not constitute a source of ignition under normal conditions"
If we interpret the use of "dusttight or otherwise identified for the location" as implying general-purpose or specifically listed then dusttight per 110.28 is suitable and need not have any additional markings beyond its type rating.
