What is A Class 2 Div 2 Area?
Class 2 Div 2 Definition
In Simple Word

Class 2 Div 2 location, C2D2 for short, Class 2 Division 2 for full name, means ignitable concentrations of hazards, such as flammable dust, exists under abnormal operation conditions.

In Quantitative Measurement

Class 2 Div 2 location means ignitable concentrations of hazards, such as flammable dust, present from 1 hour to 10 hours every year.

Class 2 Division 2 Electrical Requirements
In Accordance with NEC Article 500
A Class 2, Division 2 location is a location:

In which combustible dust due to abnormal operations may be present in the air in quantities sufficient to produce explosive or ignitible mixtures; or

Where combustible dust accumulations are present but are normally insufficient to interfere with the normal operation of electrical equipment or other apparatus, but could as a result of infrequent malfunctioning of handling or processing equipment become suspended in the air; or

In which combustible dust accumulations on, in, or in the vicinity of the electrical equipment could be sufficient to interfere with the safe dissipation of heat from electrical equipment, or could be ignitible by abnormal operation or failure of electrical equipment.

FAQ for Class 2 Div 2
Q
Does Class 2 Div 2 require explosion proof?
A
Yes, Class 2 Div 2 require explosion proof. Flammable dust do not always exist in Class 2 Div 2 locations, it seems it looks not that hazardous, anyway, some explosion proof measures such as restrict the energy of electrical circuit and control the temperature rise range still need to applied for any electrical box to be explosion proof.

Q
What is Class II and Class III in hazardous location?
A
Class II hazardous location, also called Class 2 hazardous location, are those in which combustible dust may be easily found, Class III hazardous location, also called Class 3 hazardous location, are those which ignitable fibers or flyings may be frequently produced. In practical modern explosion proof industry, when a light fixture or enclosure is designed to used in class 2 hazardous location including class 2 div 1 and class 2 div 2, it can be also used in Class III hazardous location.

Q
What is a Class 2 Div 2 area?
A
Class 2 area is made of location where combustible dusts may exist that have the potential to become flammable or ignitable. Class 2 Div 2 area is one division of Class 2 area and is classified as an area where the explosive or flammable combustible dusts mentioned above are not likely to exist during regular operation. Class 2 Div 2 areas include grain elevators, flour and feed mills, metal powder plants, and coal plants.

Q
Can I use a piece of equipment approved for use in a Division 1 hazardous location in a Division 2 hazardous location?
A
Yes, Class 1 covers Class 1 Div 1 and Class 1 Div 2, Class 2 covers Class 2 Div 1 and Class 2 Div 2, the explosive substance in Div 1 of Class 1 or Class 2 exist more frequently than ones in Div 2 of Class 1 or Class 2. Thus, equipment approved for Class 2 Division 1 hazardous location can be used in Class 2 Division 2, equipment approved for Class 2 Division 1 hazardous location can be used in Class 2 Division 2.

Q
What class and division is explosion proof?
A
Hazardous location is classified into three class, Class 1, Class 2 and Class 3, and two division, Division 1 and Division 2. Class 1 locations consist of areas where flammable

gases, vapors exist, Class 2 locations consist of areas where flammable dusts exist, Class 3 locations consist of areas where fibers and flyings exist. Division 1 is classified as an area where flammable substances mentioned above can exist under normal, everyday operating conditions. Division 2 is classified as an area where flammable substances mentioned above are not likely to exist during regular operation.
