I understand the seal off rules for entering and exiting a class 1 location as well as seal offs on equipment in a class 1 location. However, can you have fittings after these seal offs like a pulling C or T body as long as it is explosion proof rated and if so does it need to have a seal off before or after it?

Possibly, but probably not. See Section 501.15(A)(1)(2).
NOTE: The fitting cannot be between the required seal and a boundary.
I see that but confused why I always see T fittings and unsealed lights around the plant i work at in a class 1 div one location
So.even if its a class1 div 1 gua c fitting i cant us it in between ?

So between the MCC and the Div 1 location I cant have a fitting. But I should be able to have one after that once I pass the seal inside the Div 1 area. Im talking about once inside the Div 1 location.
Let me know if that is ok I believe it is
