PVC indoor use

[butch]

I had a few questions brought up about the use of PVC being used for indoor applications. Is it permissable to use PVC inside a commercial building.If its exposed and not concealed behind a fire rated wall or ceiling. Any help would be greatly appreciated. Thanks again your help has always been very professional and helpful!!

Re: PVC indoor use

Article 352 Rigid Nonmetallic Conduit: Type RNC.
352.10 Uses Permitted. (A) through (H).
352.12 Uses Not Permitted. (A) through (F).
For most commercial buildings, PVC is OK. If subject to physical damage (a judgment call if exposed) it must be identified for such use, i.e., Schedule 80. If concealed, Schedule 40 is allowed.

Be mindful of plenum restrictions. PVC does not meet the flame spread and smoke developed index for these areas.

Allen,

Does this look familiar?

(1) The electrical nonmetallic tubing or rigid nonmetallic conduit is installed concealed within walls, floors, and ceilings where the walls, floors, and ceilings provide a thermal barrier of material that has at least a 15-minute finish rating as identified in listings of fire-rated assemblies.
(2) The electrical nonmetallic tubing or rigid nonmetallic conduit is installed above suspended ceilings where the suspended ceilings provide a thermal barrier of material that has at least a 15-minute finish rating as identified in listings of fire-rated assemblies. Electrical nonmetallic tubing and rigid nonmetallic conduit are not recognized for use in other space used for environmental air in accordance with 300.22(C).

Thanks so much for your replys. I had one electrician on my job that says you cant use it indoors because of the smoke in a fire situation.Hes saying it would hide the escape route. Thanks again I sure learn alot from this forum.
