Andy, Supplement A of NEMA250-1997 contains information on NEMA Type 7. It is defined as "Enclosures constructed for indoor use in hazardous locations classified as Class I, Division 1, Groups A, B, C, or D as defined in NFPA 70." It goes on with more information than I am willing to type. Give me a call and I will read it to you. I can be reached at (317) 916-4274 extension 462. Dan Kinney Horner APG
