Hazardous Location Specification

Class I, Div 1 and 2, Group B, C, D are for hazardous locations where flammable gases or vapors may be present during normal operations, normally confined, or not present in ignitable concentrations. Class I hazards are commonly found in petroleum refineries, fuel dispensaries, sewage treatment plants, and processes using chemicals, paints, coatings, or sealants. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group B (hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein), Group C (ethylene, cyclopropane, and ethyl ether), Group D (acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene).

This rating indicates the electrical device is suitable for use with the following hazardous materials: Group B (hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein).
Class II, Div 1 and 2, Group F, G are for hazardous locations where combustible dust is present during normal operations, normally confined, or not present in ignitable concentrations. Class II hazards are commonly found in pharmaceutical factories, coal-handling plants, grain elevators, and plants processing flour, feed, or powder. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group F combustible dust (carbon black, charcoal, coal, and coke dust) and Group G combustible dust (chemicals, flour, grain, plastic, and wood).
Class III, Div 1 and 2 are for hazardous locations where ignitable fibers or flyings are present during normal operations, normally confined, or not present in ignitable concentrations. Class III hazards are commonly found in textile mills, lumber mills, and other plants with airborne fibers or sawdust.

NEMA Configuration

Phase

Phase refers to the distribution of an electrical load. Single-phase power is a two-wire alternating current (AC) power circuit. It accommodates light loads and is commonly found in homes and offices. Three-phase power is a three-wire AC power circuit. It accommodates higher loads and is commonly found in commercial and industrial buildings.

Single

Circuit Breaker

Circuit breakers protect electrical systems in the event of an overload or short circuit. Also known as circuit protectors, they shut off power when the current gets too high in order to prevent personnel injury or damage to equipment and circuitry. Unlike fuses, they can be reset to resume normal operation.

GFCI

Ground fault circuit interrupters (GFCI) are required anywhere the receptacle is close to a water source, like bathrooms, kitchens, and garages. If they experience a ground fault interruption, they will turn off the connection to help prevent shock and must be manually reset with a button on their front side.

NEMA Enclosure Rating

3 is a safety rating for indoor and outdoor electrical enclosures that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow), and against exterior ice formation.
3R is a safety rating for indoor and outdoor electrical enclosures – often called rain-tight or rain-proof – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt) or water (rain, snow), and against exterior ice formation.
3RX is a safety rating for indoor and outdoor electrical enclosures – often called rain-tight or rain-proof – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt) or water (rain, snow), against corrosion, and against exterior ice formation.
7BCD is a safety rating for indoor electrical enclosures that are constructed to keep internal explosions contained when used in Class I, Division 1, Groups B, C, or D hazardous locations as specified by the National Electrical Code (NFPA 70).
7CD is a safety rating for indoor electrical enclosures that are constructed to keep internal explosions contained when used in Class I, Division 1, Groups C or D hazardous locations as specified by the National Electrical Code (NFPA 70).
9FG is a safety rating for indoor electrical enclosures that are constructed to prevent the ignition of combustible dust when used in Class II, Division 1, Groups F or G hazardous locations as specified by the National Electrical Code (NFPA 70).
