Metal vs pvc for running line on outside of house

Thanks

PVC. You won't need to worry about it rusting out.

Hi, how long is the run? If the PVC is exposed to a lot of sun light it will need to clipped really well or it may sag.

Is PVC rated for ultra violet rays from the sun if exposed?

I would use pvc and paint it to solve UV issues.

PVC is sunlight resistant and can be installed on the house. One problem with PVC over conduit is that the PVC can be hard to run straight and keep straight. The bulk of my outdoor lighting jobs are done with 1/2" EMT.

Smile No romex in PVC

Do not put romex in your PVC, and I would use grey. So that someone else can see that there is 120 Volt inside. Check your codes, some state do not let a homeowner do the wiring. Are you going underground with this?

Welcome to the forums Brad.

This looks to be strictly an "on house" installation. It is ok to use UF in outdoor conduit but not NM-b (romex). One reason that cable is not usually used in conduit is that it's too hard to pull. The cable does not go around bends well.

All conduit outside is considered a wet location. NM-B is not rated for wet. You need to use wet rated cable like UF or THWN wet rated individual conductors.
