Hazardous Location Specification

Class I, Div 1, Group B, C, D are for hazardous locations where flammable gases or vapors may be present during normal operations. 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), and Group D (acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene).
Class I, Div 1 and 2, Group 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 C (ethylene, cyclopropane, and ethyl ether) and Group D (acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene).
Class II, Div 1, Group E, F, G are for hazardous locations where combustible dust is present during normal operations. 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 E combustible dust (aluminum, commercial alloys, and magnesium), Group F combustible dust (carbon black, charcoal, coal, and coke dust), and Group G combustible dust (chemicals, flour, grain, plastic, and wood).
Class II, Div 1 and 2, Group E, 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 E combustible dust (aluminum, commercial alloys, and magnesium), 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 may be 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.

Number of Poles

This refers to the total number of circuits on an electrical device.

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
Three

Max Current (AC)

This refers to the maximum amount of alternating current an electric device is designed to handle continuously without risking the deterioration of its components.

20 A
30 A

Hub Type

Dead End have one hole where cables enter and exit. They provide room inside them to splice, tap, and terminate conductors.
Feed Through have two in-line holes where cables enter through one and exit the other. They're used to route wires and have room inside them to splice and tap conductors.

Hub Diameter

Refers to the hole size on enclosures where power cables enter to make connections.

Factory Sealed

Designates the specified device comes with fittings sealed by a compound adhesive at all conduit entrances.

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 (snow, rain), 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, windblown dust) or water (rain, snow), and against exterior ice formation.
7 is a safety rating for indoor electrical enclosures that are constructed to keep internal explosions contained when present in hazardous locations.
9 is a safety rating for indoor electrical enclosures that protect against the entry of solid objects (falling dirt, settling dust/lint) that could cause an explosion when present in hazardous locations.

Includes Pilot Light

This refers to whether an electrical device has built-in pilot lights that turn on when the device is powered. They illuminate devices while under load to show they're on, help locate them in dark or poorly lit areas, and to prevent operators from disconnecting or servicing them while the motor is on.
