Re-useing old conduit.
Found this today while working in a local grain facility.  Somebody cut a 2 1/2" rigid and bushed it down to 3/4. Didn't even bother to cap the peice after they cut out the chunk. Bad part is I cant garantee it wasn't one of our guys.

Got'ta give him some credit for get'er done thinking. What size conductors? Or how many ,that this was his option.Tried something very similar with a pvc install going from 2 1/2 to 1 and got slammed .Had to use a 12x12. Was in the ground though.I didn't want to 90 up then 90down to complete the install.

I don't see a single problem in the picture.
If you do see a problem can you provide a code reference other than 110.12?

Don't know about PVC but if it's old EMT or RIGID STEEL forget it. unless it is over sized.
Old metallic conduit did not have the coating inside.
I can remember when pushing three #12 twh solids though 20ft of 1/2" with two 90s was imposable.

you can always lube it a tad bit and well if that conduit will save me from needing to make new holes in a concrete wall or foundation... you bet I'm gonna reuse that old pipe... just spray it with cold galvenize.. tell the customer I swaped the old for new  hahahahahaha

I have done this before, I really don't see a problem with it. I would have taken the length of conduit that is cut out to the last coupling and plugged it there though.

doubtfull.... same insulation, size, but less rigid? how does that make sense. Pushing solid wires is 10 times easier than stranded

Maybe he was thinking of pulling the wire, and in that case stranded would be easier, but like you said solid is easier to push.

I agree. Those who really want to PRETTY things up may want to remove the old conduit, but the bottom line is if it doesn't have wire in it, it is just a piece of pipe.

Fitters run pipe, electricians run conduit.
