PVC Conduits in Dry wall partitions

[Sajid khan]

Hi All,

Can anyone help me identify if it would be a problem if we use PVC conduit in drywall partitions in a hospital project? This will save us a cost compared to EMT Conduit. Will it be against the NEC rule? What could be the implications?

Regards

Take a look at 517.13 (A) and 517.10 (B).

I did not look at sections mentioned in post 2, but presuming that was addressing patient care circuits that require a wiring method that in itself qualifies as an EGC. PVC can not be used on said circuits because it doe not qualify as an EGC.

Also should you have a place of assembly within the facility you couldn't use PVC methods within that location either. Outside those two applications probably fine.

To qualify 517.13(A), can we use a separate Grounding conductor? or it shall necessarily be an EMT?

Art 517 requires a grounding conductor in a 250.118 metal raceway or cable.
Two wire type conductors are not an acceptable means.

There are types of AC and MC cable that are acceptable.

A second EGC does not comply with the wording. The raceway or cable system used shall in itself qualify as an EGC as well as contain a conductor type EGC.

You cannot use a separate or second equipment grounding conductor. The wiring method itself must be an equipment grounding conductor and must also contain an equipment grounding conductor of the wire type.

Much appreciated comments.
