Will take the advice and use 2" pvc conduit, I just wanted to make sure I can run the URD indoors but it sounds like there is different types of URD. Great forum, lots of good advice.
Long time lurker, first time poster. I'm trying to run a sub panel 125' to my newly built shop. I plan on using 2-2-2-4 alum URD in 1 1/4 pvc conduit. My question is my main panel is on a interior wall around 15' from the exterior wall that the feed line will come in at, so can I run the URD...
