Scott, if this is for an underground feeder, skip the UF, and put in a 3/4" PVC conduit instead. If you should ever have to upgrade, or have a failure in one of the conductors, you already have a "hole in the ground." The last well pump I installed using UF, we had to go back and replace the wire. A rock had rubbed against it. If it had been in pipe, it would have only meant replacing the conductors. You can use THHN in pipe buried under ground.
I do not have enough wire to offer but I too would suggest conduit instead of UF cable. It is not much protection but PVC conduit is more resistant to the errant shovel, pick, fencepost etc. than UF cable. I used conduit when I ran the feed to my shop. :wsmile:
Scott, I may have what you need. I have a roll left over from doing a garage feed years ago. I will have to climb up in the rafters and get it down. I am fairly certain there should be at least 60 or so feet and is 10/3 - I know for sure it is 10/? uf and I will dig it out in the am after watching Duke win
I put it up there in the last century and have not needed it since, so if it is correct it is yours for a cold carbonated beverage someday
