Can you run ENT in a commercial building.

you can find all the specifics in 362.10, but some of the fine print notes from that article are;


Electrical nonmetallic tubing (ENT) is permitted to be installed either concealed or exposed. Where exposed and subject to physical damage, ENT is required to be protected and is limited to use in buildings not exceeding three floors above grade, as explained in the first paragraph of 362.10. Where concealed or above a suspended ceiling (exposed), ENT is permitted to be installed within walls, floors, or ceilings in buildings of three floors or less without the need for fire-rated construction. The three-floor limitation is based on the likelihood that only a small quantity of ENT will be exposed to fire and that the occupants will have adequate time to exit the building before the products of combustion make the building untenable. Exhibit 362.2 illustrates permitted uses of ENT in a building of three floors or less.

Also, check the exception for buildings that have sprinkler systems on all floors, that will extend the uses of ENT as well.
The few commercial jobs I have seen forbid use of ENT in their invitation to bid, making decision making process easy. e/m
