Romex in commercial building

[mshields]

Did a survey today of a 20,000 square foot commercial building. It'a abandoned now but it was a Machine shop/distributorship/office space facility.

It is 2 stories and of concrete and wood construction. i.e. the roof is wood, the walls are cynderblock. Presumably the interior walls are wood as well.

The entire place is wired with Romex to which my knee jerk reaction is "code violtation". However, in reviewing NEC 334, there is a provision for using Romex in more than just dwelling units. 334.10 states that it may be used in "Other structures permitted to be of Types III, IV, and V construction". Since I've got a partially wooden structure, I'm assuming I've got a building in one of these categories. I'm therefore also assuming that Romex is permitted. True?

There are some area's where there are suspended ceilings and where Romex is run above these. In these instances I can see that 334.12(2) gives me a violation.

Would very much appreciate your feedback.


thanks,

Mike

Remember that Massachusetts amendments more than likely allow everything you've just described. I don't know the amendments verbatim but that sounds ok to me.

Facility is actually in Hartford Connecticut

Which is a another question. I've not done work down there before. Do they have an extensive ammended version of the NEC like Mass, or do they follow the NEC pretty much verbatim like, say, RI?

Thanks,

i want to say in mass, if the bldg holds more than 100 or more people, it's considered a place of assambly, in which u have to wire the bldg in mc. i could be mistaken though.

ive used romex in commercial buildings tons of times. we use MC when the building has a plenum celing or if its a place of assembly. MA is pretty good when it comes to NM rules
