Just wondering if it is legal to the code to put NM romex cable
underground when it's inside of plastic conduit. I was going to run
individual strands of wire but found it was cheaper to use the ronex
and just shove the romex thru which eliminates several connections
too. I know it will physically work, but I am not sure what the code
says. The conduit is glued and brought above the ground level so it
wont fill with water. This is 12-3 w/gnd NM feeding a shed with two
120V 20A circuits
It is illegal. The reason is that the conductors in NM are not made for wet
locations and any underground conduit is considered a wet location, with I
think a few exceptions like maybe deserts. Despite the fact that the
sections are glued, I've never opened an underground pipe that wasn't wet
In Virginia, it is legal. But you vave to run it through the Grey
Schedule 80 Electrical PVC. It also has to be burried below the frost
line. You have to have the inspector come out and verify the PVC, Depth
and Connections before you cover it up. You should call your city codes
department and take their advise over this newsgroup.
The conduit is almost a requirement on this farm. This whole place is
covered with those damn moles. I dont know if they chew wire or not
but they sure are annoying. Maybe I will run UF cable inside the gray
PVC though. Out here in the boonies, no one really inspects much of
anything but I'd rather have it legal anyhow.
