I have a motor has a rating as Class 1, Zone 2, IIC, T3.
I've read through NEC 500 and 505. I see the definitions of "Explosion Proof" in 500.02. I see the definitions of the Class, Zone, Material Group, and temperature designation in various sections of NEC 505.
1) Is there a way to tell if this is an "Explosion Proof" motor just from this information?
2) Is there a way to tie the concept of "Explosion Proof" to the "Class, Zone, Gas, and Temp" ratings.
3) On the nameplate there isn't an explosion protection standard (for example: AEx-NEC) nor a method of explosion protection specified on the nameplate.
