Cast iron electrical conduit

Interesting way to get a wire from the basment to the attic.

It is creative, but that’s legal. That cast iron soil pipe is aparently abandoned. The romex is not required to be in a raceway. That soil pipe is being used as a convenient chase from the basement to the attic, aparently. No different than if you drilled holes in the top and bottom plates of the partitions and fished it through that way. My only concern would be that it doesn’t pass hard over any sharp edges on the way in or out of that chase. Electricians sometimes use abandoned chimneys as a wire chase from the basement to the attic, particularly when the chimney has been torn down below roof level, and you have the open square hole in the attic as a path straight to the basement. You’d be silly not to take advantage of it.

Hi Mark, I agree, the biggest “criticism” I could come up with is the small amount of rain water that will run into the basement :smiley:

Uh… how does that meet the support requirments for NM?

(B) Unsupported Cables. Nonmetallic-sheathed cable shall be permitted to be unsupported where the cable:
(1) Is fished between access points, where concealed in finished buildings or finished panels for prefabricated buildings and supporting is impracticable

hum… “access point”

Maybe they installed a heated toilet seat?? :mrgreen:


Well, I sorely hope this pipe no longer daylights on the roof of the home. Guess you’re saying it does, though.

My only concern would be a physical damage issue if the end of that cast pipe was rough.
Assuming it is not punching through the roof. If it is, you would have to call it a wet location

Having once been a 24 year old, rehabbing my own buildings after a few years experience in construction, and looking back at 60 on the stuff I did then, I look at the same stuff during an inspection today, and wonder … “what else?”

Or you ask yourself, “What the heck was I thinking?” :mrgreen:
