In this project (only 400 ft) it may be anvantages to use conduit since I have underground utilities to cross and deal with and like you said it would be nice to just deal with them once. Thanks again. Roger
You will not be sorry. I know this is not the size and length you are looking for, but this is a common size for RV use. Just for comparison these numbers are from Home Depot, You may be able to beat them at a wholesaler or contarctor supply and for sure you can get longer than 10' sticks of conduit.
500' 6-3 UF-B (direct bury) $1488
500' 6-3 NM-B $847 + 500' 2" elec conduit $324 = $1171
500' 3 x #6 THHN, 1 x #10 THHN $754 + 500' 2" elec conduit $324 = $1078
I just purchased these items for my water well and RV projects last Fall minus the conduit and the ground wire. I used one of the smaller wiring that I was replacing for a ground wire. I had about 3' of each color wire left over.
