0031 Mineral Processing

[chris kennedy]

I'm trying to determine if the above Building use classification would be considered a Class II location by the NEC. When I plug the title into a search engine I come up empty.

Thank you.

Wouldn't that be something determined by the inspection department?

Don't know. I'm trying to find out if anything used in the use/manufacturing of concrete may produce dust that would fall under 500.5(C). This is an existing plant that had a 40 electrical system inspection by an EE. I'm bidding 99 pages of PDF's with 85 photo's. Due tomorrow.:roll:

A cement plant in this area was refurbished a few years back. As I recall, there were certai n area that were Class II due to the presence of certain addatives, perhaps a calcium silicide.

In general, this article may help:

I e-mailed the inspector who worked that project and asked him to add from his experience (he is a member here)

The best I can remember that had several locations that the equipment had to be dust proof and a testing building that was a classified location . In Chattanooga the Inspection Department requires that the classified area are determine by and Electrical Engineer on the Plans . Maybe this will help you.
