Where would I find a definition pertaining to "Crawlspaces"? I need to know what the "NEMA" rating would be as it pertains to boxes, gear, MC cable, etc. The question concerns some area that is subject to moisture.
There is no definition in the NEC pertaining to crawl spaces. If the question is moisture I would think that the AHJ would be able to make a decision as to that. Unfortunately the NEC is not much help.Where would I find a definition pertaining to "Crawlspaces"?

I may not be able to define "crawl space", but I know one when I see one.
I guess it's an unfinished space too low to finish and use as habitable space.

Yes.So, your saying if the ceiling is at 6'11" then it is a crawlspace.
That's why I say 'yes'. There's no rule that says you can't stand up in one.The International Codes refer to them as "unhabitible under-floor spaces".
From what I've read, that's more energy-efficient than a ventilated space below an insulated floor.I don't if this will help, but the IBC and IRC allow you to have unvented crawlspaces if you put down a 6 mil vapor barrier, insulate the crawlspace walls, and condition the space; thereby mitigating the moisture problem.
I have not found a clear and concise definition for crawlspace either. The International Codes refer to them as "unhabitible under-floor spaces".

So that's why they have locks on crawlspace doors.I've found them living in crawlspaces before. The homeowners were not aware someone was sleeping under their house at night.
