NEMA Enclosures
The following information is transcribed from the requirements of NEMA and the American Institute of Electrical Engineers covering various classifications of the Underwriters’ Laboratories. These requirements are listed for reference purposes only. They are taken from the requirements of the approval associations or engineering groups. They are not necessarily an indication of what should be sold in the way of control apparatus. GC Valves does not supply all types of enclosures on all valves designs.
Contact GC Valves Customer Service for specific combinations.
NEMA Enclosure Types
In non-hazardous locations, the specific enclosure types, their applications, and the environmental conditions they are designed to protect against, when completely and properly installed, are as follows:
Type 1 – Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt.
Type 4 – Enclosures constructed for either indoor or outdoor use to provide a degree of protection against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external formation of ice on the enclosure.
Type 4X – Enclosures constructed for either indoor or outdoor use to provide a degree of protection against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and corrosion; and that will be undamaged by the external formation of ice on the enclosure.
NEMA 7 & 9 Refers to Indoor Hazardous Locations – Air-break Equipment
Class I Refers to locations in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Group C – Acetaldehyde, Cyclopropane, Diethyl Ether, Ethylene, Isoprene, & Unsymmetrical Dimethyl Group D – A wide range of gases and vapors including gasoline, propane, natural gas, methanol, acetone, butane, benzene, octanes, toluene, and xylenes
Class II Refers to locations which are hazardous because of the presence of combustible dust. Group E – Atmospheres containing combustible metal dust Group F – Atmospheres containing carbon black, coal or coke dust Group G – Atmospheres containing flour, starch, or grain dust
Class I and Class II also have the following designations: Division 1 refers to hazardous gases or dust that exist continuously Division 2 refers to hazardous gases or dust that do not normally exist but may exist due to equipment failure etc.
Our explosion proof housings are not approved for: “Group A” Acetylene “Group B” Butadiene, Ethylene Oxide, Hydrogen, Gases containing more than 30% Hydrogen, and Propylene Oxide.
