These light posts are a recent installation. There are a couple dozen or so all done this way. Yes that is copper tubing.

Wow, Is this OK in your area, Scott?

I know it is weird and it would have not been my choice, .....but.

If that is UF inside that pipe it would seem to comply with 334.15(B)Protection from Physical Damage.

In that article they list all sorts of raceways plus

"or other means"

"or other metal pipe"

I really don't see a problem if it is UF, if it is single conductors that would be a problem.

I would question how it was installed. If it was pulled through that 90d plumbing fitting, that would make some serious pulling resistance and heat possibly exposing conductors.

And speaking of heat - is that fitting soldered? If so I hope it was before the wires were put in but then that points back to the first problem.

Persoanlly I do like the idea of copper for cosmetics in this appliaction as it will turn patina over time. But one must consider a safe way to use it.

I couldn't tell what kind of wire was in there. Maybe next time I pass by I'll climb up and take a closer look. I got some strange looks when I was taking these pistures!

That being a weather resistive box, would be interested in how / if they managed the threaded fitting that would probably need to be soldered to maintain the intergrity of the assembly .. I can understand the intent of the copper .. they want it to weather out so it compliments the antique lantern looks. ERFERTT

The elbow looks like it has been soldered to me.
Did they use a hose bib at the top to form a drip loop for the wiring? [Linked Image]

Every time I have seen soldered copper pipe next to wood, I have seen black marks on the wood. The wood next to this "conduit" contain no black marks. Which means that the "conduit" was assembled at a remote location and latter installed. If that were the case then how did the installer get tat last 90 into the box. Is there any "conduit" inside the post.
