Re: PVC Electrical Conduit
conduit would be mfg per a UL listing, color is not a NEC issue.
Water pipe would be mfg per a NSF - national sanitation foundation - standard.
What color would water pipe with wires in it be?

Re: PVC Electrical Conduit
I believe they are also different materials. I don't know if that is what determines the colors but I doubt that the different colors are to distinguish the uses. Isn't or wasn't there a gray plastic water pipe also?

Re: PVC Electrical Conduit
My neighbor asked me to look at his shed light, it was not working, i found water pipe used as a raceway, with water pipe fittings and 14 NM cable put inside, there was not much pipe left, the sun had destroyed most of the pipe, it was buried 6" below the surface, not all pvc is sunlight resistant pipe, like electrical pvc is.

Re: PVC Electrical Conduit
I was told that "water pipe pvc" produces a toxic gas when burned or melted, but gray electrical pvc will not produce the harmful gases, such as if a ckt is overloaded, or if the pipe was exposed and caught fire somehow. Anyone else?

All PVC makes toxic gasses when heated above about 400? or 500? or when burned.

All plastic is not equal, and colors don't always say everything.

Re: PVC Electrical Conduit
I have found access to both the UL and NEMA listings for PVC conduit, they do not specify a color, as you would exspect only a reference to product markings...
Would love to hear from a manufacture on this, I am of the thinking this an industrial "prefernce"?
