grain elevators

[electriciansd]

Is it allowed by the NEC to use weatherproof bell boxes inside the elevator where grain is being handled

Is it a Class 2 Division 1 location?

Likely yes.

Have you ever seen a bell box rated for hazardous locations?

 

[cowboyjwc]

I would say that it's not allowed.

 

[augie47]

Possibly for nonincendive wiring.

What is in the bell box?

 

[ptonsparky]

The bell box would be no worse or better than the typical conduit body that is allowed. How is it being used?

I belive that the correct answer after further research is yes bell boxes are permitted for all wiring as long as they do not contain taps joints or terminal connections. Bell boxes meet the standard set forth in 502.10(A)(4)
