An enclosure with a UL stamp of being rated for Class I, Div 1 does NOT mean that it is approved for a Zone 1, Group IIA/B, T4 area. Even with same temperature and gas ratings, the approval stamp on the equipment must match the area rating. There is no requirement for a seal on the NEMA 4 box that contains splices where the enclosure is in a Class !, Division 2 area. Enclosure seals in those areas are only required if the enclosure is required to be of explosion proof construction. 501.15(B)(1) in the 2008 code. There is differing opinions on the question of the transmitter seal. RE: Class 1 Div 1/2 enclosure question controlnovice (Electrical) 20 Aug 09 17:07 I think NEC 500.8(D)(1) states that Listed conduit, conduit fittings, or cable fittings shall be used for equipment provided with threaded entries.
If you have a Class I hydrocarbon contained inside an enclosure then the internal rating could be Division 1 instead of Division 2. The rating of the internal piping or tubing would be Division 1, Zone 0. You cannot eliminate the hazard of leaking propane or gasoline inside the enclosure by increasing the differential pressure. Could someone please provide me with a reference/standard for use of batteries (12VDC) in a Class 1, Div 2 area - specifically what limitations there might be for placement of a battery within a NEMA 8 enclosure at an outdoor facility? The battery would be powering an intrinsically-safe sensor. I am installing equipment in a hazardous (C1, D2) location. All the instrumentation is XP rated for this area. The enclosure is also located in this classified area. The enclosure is a NEMA 12 type with an argon purge. As I interpret my NEC manual, that should be suitable. I have used seals and meyers hubs to enter this enclosure. Can't find the answer. I want to put a netgear wireless 802.11 router in a nema 4 enclosure. But i need to put an external antenna. Do i have to find a class 1 div. 2 wireless router? Do i have to find a Class 1 Div. 2 External antenna, which i can't find so far? Can i .
My comment "I don't believe that you can use NEMA 4X enclosures in a Div 1 area." is wrt what I believe that a motor OEM will normally provide on a motor designated for Class-1 Div-1 rating. ie I have never seen a motor OEM supply anything other than cast explosion-proof boxes on such a motor.

Our sales force year in and year out seem to get a mixed bag of opinion on this, but whenever it seems that the opinion shared is, "I believe Class 1, Div 1 is going away and you will see the whole market switch to Intrinsically Safe, Purge, etc. away from explosion-proof", we seem to sell more Class 1, Div 1 enclosures.
