Does Class 2 Div 2 require explosion proof?
A Class I Division 2 light are not held to as high of a standard as Division 1 products. To meet the requirements for Division 2, a light does not have to be able to contain an explosion. Instead, they must be found to be unable to cause an explosion in environments for which they are approved to be used.
What is a Class 2 explosive?
Class II Locations The second type of hazardous location is called a “Class II Location”. This classification is created by the presence of combustible dust in the air in sufficient quantities to be explosive or ignitable.
Is a Class 1 Div 2 motor explosion proof?
While Division 1 motors in Class I locations must be explosion-proof, Class II, Division 1 motors must be dust- ignition-proof. The characteristics of dust-ignition-proof motors differ from those of their Class I counterparts.
What NEMA rating is explosion proof?
NEMA 7
NEMA 7 Indoor use in locations classified as Class I, Division 1, Groups A, B, C or D hazardous locations as defined in the National Electric Code (NFPA 70) (Commonly referred to as explosion-proof).
Is intrinsically safe the same as explosion-proof?
WHAT IS INTRINSIC SAFETY AND EXPLOSION PROOF? Therefore, Intrinsically Safe means that an apparatus, such as a temperature transmitter is not capable of causing an explosion. Explosion Proof means that should an explosion occur, it will be contained within an enclosure.
Is IP65 explosion-proof?
Our range of LED ATEX Rated IP65 ExD Explosion Proof Linear luminaires provide an energy efficient replacement for all traditional ATEX rated floodlight fittings, such as 100W and 250W ATEX rated son fittings often found in oil and gas storage areas, chemical plants and other areas within explosive atmospheres.
What is a Class 1 explosion proof location?
Explosion Proof Classifications Class Definitions Class I Locations: Are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class II Locations: Are those which are hazardous due to the presence of combustible dust.
What are explosion proof connectors?
What are Explosion Proof Connectors? Explosion proof connectors are designed to be used in intrinsically safe circuits of categories “ia”, “ib,” and “ic” of explosion protection method “Ex..” The series can be used in Zones 0, 1, and 2 for gas and Zones 20, 21, and 22 for dust.
What is an explosion proof HVAC system?
“Explosion Proof.” is a term for HVAC equipment built for Hazardous or classified environments.
What is a Class II hazardous location?
Class II locations are those which are hazardous due to the presence of combustible or electrically conductive dusts. The dust must be present in sufficient quantitiesfor a fire or explosion hazard to exist. The fact that there is some combustible dust present does not mean a Class II hazardous location exists.
