dusttight also has to do with boxes and fittings, etc. better look at 501 nec, definition of dusttight and class 1 div1 locations, wiring methods. at a quick glance, not approved unless its encased in 2 inches of concrete.
If in a flour mill or other processing facility where the dust is frequently airborne, it could be a hazardous location. If you put compression fittings into standard NEMA 1 cabinets and boxes you will still get the dust into the enclosures. There was a bell box with lever switch cover in this area running a fan for summertime air flow. The fan's motor is rated for this area. At the time I thought maybe because the box is gasketed it is ok to have in this area. NEC 2011- 502.10 (B)(4) : All boxes and fittings shall be dust tight. The question is: Does a Technical Product Certification form a product manufacturer, be used in lieu of a product standard and an NRTL listing. Section 502.10(B)(4) requires boxes and fittings shall be dust tight, and I could not find an NRTL that does list EMT fittings as being dusttight. As I read the code for Class 2 Div 2, I read that EMT is allowed. I would assume only with compression type fittings to remain dust tight. Do my entrys into the junction boxes and control panels need to be sealed within this area? If so, can a gasket be used as a seal?
The general requirements for boxes and fittings in Class II, Division 2 is in Section 502.10(B)(4).

Fittings and boxes in which taps, joints, or terminal connections are made, or that are used in Group E locations, shall be identified for Class II locations.”. I have a hard understanding this language. That case has no effect on electrical boxes, they are inside the air barrier already. Another option is to use the interior drywall on exterior walls as the air barrier (although things get tricky at intersecting interior walls). If you do that, then you need air barrier electrical boxes, as the box is interrupting the air barrier. Cheers, Wayne
