Does Class 2 div 2 require explosion proof?
The motor’s nameplate indicates that the motor is approved for Class I, Group D, and Class II, Groups F and G, with a T-code rating of T3B. As with the use of explosion-proof motors in Class I, Division 2 environments, dust-ignition-proof motors are acceptable, but not necessary, in Class II, Division 2 areas.
What does Class 2 div 2 mean?
